Whey protein is a popular supplement for the many out there who exercise or take their health and fitness seriously. It helps with building muscle, recovery, and provides essential amino acids that support your body in many of its functions. On the other hand, though, many whey protein supplements are high in calories and have a high sugar content.

In comes PhD Nutrition Diet Whey Protein, which claims to be different than traditional whey protein powders. For starters, it has less calories and carbs than other protein supplements. It also consists of more CLA, flaxseed, and L-Carnitine than other options. This product is meant for increasing lean muscle mass while reducing body fat.

In this PhD Nutrition Diet Whey Protein review, we’re going to talk about what we found when we took a closer look at this diet Whey powder. We’ll go over what’s in it, how it tastes, who should use it, and more. Read on to find out if PhD Diet Whey Protein Powder is a good fit for you and how our review experience came out.

Whey protein - helps with building muscle

What Is PhD Diet Whey Protein Powder?

PhD Nutrition Diet Whey Protein is a protein supplement from PhD Performance Nutrition, the same producers as well-known testosterone booster PhD Test Matrix . PhD Nutrition Diet Whey Protein combines ingredients for targeting muscle building with those that support increases in energy and fat loss. It’s a high-protein, low-calorie blended supplement designed to help people reach their fitness goals.

The idea is not to put on a lot of fat when you’re working on toning your muscles. PhD keeps the carbohydrates and calories low, but the protein high in a serving of its PhD Diet Whey Protein Powder. PhD adds other ingredients that boost energy, increase fat burning, and promote better digestive health.

How Does PhD Nutrition Diet Whey Protein Compare?

PhD Diet Whey Protein Powder has 91 calories per 25 gram serving of the supplement. Traditional whey protein supplements often have anywhere from 110 to 160 calories per serving; for example, you’ll find 130 calories per serving in Bowmar Nutrition Whey Protein and 160 calories per serving in Gnarly Whey . The tricky thing to remember when you’re comparing protein powder supplements is to look at the serving size. They may not be the same.

PhD Nutrition Diet Whey Protein has less than 2 grams of fat and less than 3 grams of carbs per serving. The fat content and carbohydrates of other protein powders varies widely across the board.

PhD sets their product apart by adding more of certain ingredients to help boost the effectiveness of their protein powder. So, let’s take a look at what’s in this protein supplement.

PhD Diet Whey Protein Powder Ingredients

The ingredients in PhD Diet Whey Protein Powder add for extra muscle building, and fat burning power are CLA, flaxseed, and L-Carnitine. So, let’s talk about those and what they bring to the table.

CLA (Conjugated Linoleic Acid) – CLA is an omega-6 fatty acid that has many benefits for your body. Research shows there may be a link between CLA and weight loss. It decreases the amount of body fat you have. Other benefits may include preventing cancer and type 2 diabetes, as well as heart disease.
Flaxseed – Ground flaxseed improves your digestive system. It’s high in fiber and consists of omega-3 fatty acids. People use flaxseed to relieve constipation. It’s thought to lower the bad cholesterol level, too.
L-Carnitine – This amino acid improves cognitive function and stimulates weight loss. L-Carnitine is said to convert fat into energy for your body. The fatty acids enter the mitochondria (power producer in cells), where they are burned to create an energy source.

PhD Nutrition Diet Whey Protein has 750 milligrams of flaxseed powder per serving. It also has 375 milligrams of CLA and 125 milligrams of L-Carnitine.

PhD Diet Whey Protein Powder Flavors

PhD Nutrition Diet Whey Protein comes in more flavors than most other protein supplement brands. Here’s a list of their inventive flavors:

Vanilla Creme
Belgian Chocolate
White Chocolate
Chocolate Mint
Lemon & Blueberry
Salted Caramel
Chocolate Peanut
Cookies & Cream
Chocolate Orange
Royal Milk Tea
White Chocolate & Raspberry
Birthday Cake

Keep in mind some of the ingredients and nutritional information may vary a little from one flavor to another.

PhD Diet Whey Protein Powder Customer Reviews

We’re all different, but it’s helpful to hear what others who already use the protein have to say about their results and how the product tastes.

For the most part, users say they like the taste of the protein. Overall, Banana appears to be one of the favorite flavors. Belgian Chocolate and Vanilla Crème are also popular. Most reviewers say the mixture comes out thick but without lumps. The one common negative was from users saying the flavors taste too sweet.

Customers of this product say it works well to keep them full. It blends easily and has a smooth texture. They also mostly say it’s excellent for providing the nutrition they’re looking for. It’s a good value.

Users say they like the boost they get for their recovery when having this protein supplement. Generally, people like PhD Nutrition Diet Whey Protein as a post-workout supplement .

Who is PhD Nutrition Diet Whey Protein Best For?

PhD Diet Whey Protein Powder is the ideal supplement for people looking to gain lean muscle mass while cutting body fat. It’s high protein but low calorie and sugar.

PHD Diet Whey Protein - gain lean muscle mass

Though it’s not the right choice to include for anyone looking to bulk up. PhD Diet Whey Protein Powder isn’t engineered to add bulk to someone. While it supports muscle recovery and growth, it isn’t mixed for building large muscles.

Some people are allergic to whey protein. If you know you are or have a sensitivity to it, do not use PhD Nutrition Diet Whey Protein.

Is PhD Nutrition Diet Whey Protein Safe?

No protein supplement should be taken in excess. Too much of the added ingredients could result in negative side effects. But we want to focus on any possible side effects from using the supplement as intended.

Users report some instances of belly aches, cramping, and diarrhea. Some people said they felt sick after drinking their protein shakes. These are symptoms that many may experience when they drink protein supplements. PhD Nutrition Diet Whey Protein doesn’t have a lot of this reported, but there are some users indicating these side effects.

Is There Data to Back Up PhD Nutrition Diet Whey Protein?

There is scientific research that supports the benefits of specific ingredients in PhD Nutrition Diet Whey Protein. What we don’t see are any studies done by third parties of the product itself. PhD has yet to come out with any proof their supplement does what it says it can.

Where to Buy PhD Diet Whey Protein Powder

PhD Diet Whey Protein Powder is available in 3 sizes, with savings at each level. We will detail the pricing and savings below.

PhD Nutrition Diet Whey Protein Pricing:

500G – £12.74 / $17.12 (save 15%)
1KG – £19.19 / $25.78 (save 40%)
2KG – £29.50 / $39.64 (save 50%)

With three sizes/pricing tiers, savings at each order level, and 14 flavors to choose from (including options like Birthday Cake and Salted Caramel), there seems to be something for everyone when it comes to PhD Nutrition Diet Whey Protein.

Claims vs. Reality

PhD claims their Diet Whey Protein Powder is formulated with a high-protein, low-calorie blend. Which it does, at first glance. When you compare this supplement to other protein powders , make sure you look at the serving size indicated on the package. You want to make your comparison across a level playing ground.

The company also claims these powders have “market-leading taste and mixability.” The mixability does check out. Customers report it is easy to mix, and you aren’t left with lumps. The claim on taste isn’t full proof. There are reports that users like the taste. However, some users also report a fake or unpleasant taste.

The final claim we’ll look at is that PhD adds more CLA, flaxseed, and L-Carnitine than other brands. This claim is supported. The ingredients in protein powders vary widely across different brands of supplements. Some makers keep ingredient levels a secret due to proprietary formulas, but we can usually see if an ingredient is part of a supplement.

Conclusion: PhD Nutrition Diet Whey Protein Review

PhD Diet Whey Protein Powder is a high-quality supplement that works as a meal replacement or a post-workout recovery drink. The flavor assortment is large, meaning there is a flavor out there for everyone’s taste buds to enjoy.

PHD Diet Whey Protein - Raspberry and White Chocolate Flavour

PhD Nutrition Diet Whey Protein is also ideal for anyone looking to promote more lean muscle mass and less body fat. The added ingredients are targeted at trimming off fat while helping muscles recover quicker. While it is a good protein supplement, it isn’t right for everyone. You may need to do some tasting to find the right flavor, also.

In short, we think PhD Nutrition Diet Whey Protein is a good quality protein supplement that may not be right for everyone, but will work well for some.

PhD Diet Whey Review

Used as a healthy snack between meals or a post-workout protein hit, this great tasting supplement is ideal for anyone looking to burn fat while building/maintaining lean muscle. Another excellent product from PhD Nutrition.

There are a few things in life which I find overwhelmingly mundane.

Washing up, baby photos, the Victorian era (it’s just too long), Hugh Grant, anything by Jane Austen…

Another is dieting.

It’s just so difficult to summon up the enthusiasm to eat couscous and carrots, day in, day out.

It’s comparable to someone confiscating all of your high-def niche pornography and forcing you to rub one out over an old oak tree instead.

It’s just not the same.

Having said that, during my last foray into dieting/cutting/getting spectacularly shredded, there was one oasis of flavour, one meal which I genuinely looked forward to guzzling down each day.

That was PhD Diet Whey .

Product overview

Essentially it acts as a healthy, low-carb snack alternative or a convenient source of protein post-workout.

Per serving, you’re looking at about 35g of protein (whey protein, milk protein concentrate, soya protein isolate), 7g of low GI carbs, and 2g of sugar.

This blend of ingredients helps keep you feeling full throughout the day and should help eliminate those pesky sugar cravings.

PhD Diet Whey also contains added nutrients to help boost fat loss and maximise performance and energy levels, such as green tea, CLA, l-carnitine, waxy vol and flaxseed.

Personally, I’ve never heard of some of those ingredients – they could well be made up:

Marketing Exec 1: “Paul, how can we make this supplement more appealing?”

Marketing Exec 2: “Have you tried making up a load of impressive sounding ingredients? They fucking love that.”

Marketing Exec 1: “What about… Waxy Vol?”

Marketing Exec 2: “Bingo!”

Taste and texture

At the time of writing, PhD Diet Whey is available in five different flavours: vanilla, strawberry, Belgian chocolate, white chocolate, and chocolate orange.

I usually opt for the vanilla flavour, which, although quite sweet, tastes tremendous.

So much so I found myself having cravings for it.

The shake mixes well with no lumps in sight, but it is a little grainy, which is apparently due to the flaxseed.

I blended it with semi-skimmed milk (always tastes much, much better than with water) and would often throw in a banana or some other frozen fruit for a great tasting protein shake.

Effectiveness

Over the course of a month, I lost quite a few pounds, ‘leaned up’ considerably, and felt much more energised during training while using this supplement.

This was alongside three weightlifting sessions and three HIIT cardio session per week, as well a wholesome low-carb diet .

Obviously, it’s paramount that you use PhD Diet Whey in conjunction with a healthy lifestyle.

If you just spend all day sitting in your pants, playing Grand Theft Auto and eating Belgian buns, this shake is not going to help you lose weight or gain muscle.

The ‘slow release protein blend’ definitely helped to eliminate any cravings I normally have during the day.

Usually I hoover up every calorie in sight, with an appetite as indiscriminate as it is voracious, but PhD Diet Whey satiated this binge mindset considerably.

On a side note, PhD Diet Whey also digests very well.

Unlike a lot of other protein supplements that I have reviewed , it thankfully doesn’t leave a trail of toxic guff gas lingering behind you all day long.

So if you’re consistently smoking your other half out with volley after volley of noxious protein farts, this supplement should help ease tension in the relationship.

Value for money

The recommended retail price for PhD Diet Whey is usually £30 and £40 for a kilogram, which is a little steep in my opinion.

However, if you shop around online you can normally knock at least £10 off this price, making it much better value for money.

PhD Diet Whey is the ideal supplement for those looking to maintain muscle tissue while cutting down on fat.

It works perfectly as a low calorie snack between meals and/or post-workout protein fix, and helps keep those pesky sugar cravings at bay.

In addition, its great taste helps take the edge off those ineffably mundane diet plans.

All in all, another excellent product from PhD Nutrition.

Highly recommended!

Buy PhD Diet Whey

Typically cheapest place to buy PhD Diet Whey is here at Amazon where it normally goes for well below the recommended retail price.

If you’ve tried PhD Diet Whey and have an opinion on it, I’d love to hear from you.

Just hit me up with your thoughts in the comments section below.

Also, if you happen to find anywhere cheaper than Amazon, please get in touch.

Until then, stay strong and stay shredded!

Henry is the founder and editor of GymTalk. He spends most of his time sat at a computer shovelling peanuts into his mouth while trying to think up new ways to end sentences with the word “vagina”, but occasionally can be found at the squat rack or playing piano in Luton’s “second best” rock band.

One important caveat, however, is that while a split routine will yield initial results (“newbie gains”), they are, in the long term, far inferior to full-body routines which have you hitting the main compound lifts multiple times per week, allowing you to progress much more efficiently in terms of size and strength.

Check out out some of our workout reviews for more info – and do let me know if you have any further questions.

I’ve just brought 2kg Phd Diet Whey from Costco for about £28 with a free shaker.

Bit gutted cos I brought a 1kg £32 from Holland & Barrett the day before.

I’ve only just started using it as I’ve put a lot of weight on due to medication for depression and bipolar.

I go to the gym every day, I do 1 hour plus cardiovascular and about 3/4 hr doing weights.

Hopefully in a few weeks I will start to notice a change in my weight and muscle mass.

If there’s any advice for me it would be much appreciated.

Also do you think I should take the Diet Whey before I go to the gym?

Hi Richard, thanks for stopping by.

The advice I would give to you is to make sure you’re getting the most from each workout and not just spinning wheels.

Cardio-wise, make sure you’re focusing on high intensity interval work (sprints, bag work, etc) which is much more effective at expediting fat lass and also more time-efficient.

With lifting weights, make sure you’re focusing on the main compound lifts (squat, deadlift, bench press, rows, dips, pull ups, etc) as they will give you much more bang for your buck in terms of strength and muscle gain – and will also burn more calories and help with fat loss.

Also remember that less is sometimes more.

Three decent sessions per week (with lots of time to rest and recover) will, long term, be much more effective than seven mediocre sessions every week.

Also, working out less will leave you more motivated to get back in the gym and you’ll probably enjoy your workouts a lot more.

Hope that helps – and let me know if you have any further questions 🙂

All the best with your training!

Hi I’m training for a triathlon so I am doing a lot of cardio but pushing myself hard but also doing a small amount of weights.

Should I be taking the Diet Whey as I would like to shift some more pounds?

Yes, any protein supplement will help with a strenuous regimen such as yours, as it’s an absolutely vital macro-nutrient for maintaining a healthy/fit body.

If your goal is also to loose some extra weight, then I would absolutely recommend PHD Diet Whey, as it has a heap of extra ingredients to expedite fat loss.

I was quite excited to hear about this product until I read that you punched a cat for staring at you.

I certainly hope that you got reported for it.

I didn’t get reported for that, but I did get reported for dropkicking on owl and then hammer throwing an otter over the roof of a local Burger King.

Recently I started going to the gym and I am thinking to buy this product.

Before I purchase this product I would like to ask you a question which makes me think to buy or not.

Nowadays I don’t have any weight problems also I don’t wanna get kilos and also wanna build a muscle body.

Do you think this product is the best to purchase to achieve my goal?

Thanks SAFA

Yes, supplementing your diet with added protein will aid muscle recovery and growth.

Which flavour tastes better then all?

Vanilla is the tastiest IMO

Can I take it 2 times a day?

Like for snacks after breakfast and before bed?

Or 1 time per day is enough?

As many as is necessary really.

Try to think in terms of meeting your daily quotient, which should be around 1 to 1.5g of protein per pound of bodyweight.

Hi, I’ve been taking the vanilla flavoured Diet Whey in a smoothie along with 2 bananas and coffee every morning for breakfast for over a year now.

It keeps my bowel regular after I had a bowel op over 2 years ago.

I look forward to taking it and miss it if I don’t have it.

I occasionally swap the bananas for blueberries omitting the coffee.

I’m 66 years old so the only exercise I do is walking but I’m always busy during the day.

Should I be doing more ?

I would always recommend more exercise – but if you’re doing as much as you can and eating well, then that is absolutely fine.

What do you know about the PhD meal replacement powder is that any good/good idea?

Or is it better to take the Diet Whey between meals as you previously recommend rather than replacing an entire meal with it?

I would always advise against relying on meal replacement shakes to lose weight.

They’re not a sustainable option and starve your body of essential calories/nutrients, which, more often than not, will send your body into an “emergency state” where it clings on to body fat instead of burning it.

Instead, take a protein shake, such as this one, between meals to get your daily protein intake to around 1 to 1.5g per pound of bodyweight.

Have just started my gym a month ago and used to earlier have my routine running and excercise.

Now I wish to go for good muscular body, I’m aged 27 years and weight is 88kg with 6 feet height.

Would like to know with your experience which PHD protein – should I opt for it to grow my muscles better and more strengthening?

Hi Dilawar.

Certainly – I would always recommend supplementing a diet with protein if your goal is to gain muscle.

Last year I lost 4 stone.

I walk at least 15k steps a day & count calories.

I’ve just started back doing work out DVDs yesterday.

30 Day Shred.

I’m 29, female & 10st 2, 5’6″.

I won’t be able to do the DVDs everyday, but I will be walking everyday.

I’m weaker now due to no strength training during weight loss.

I want to get my strength back, but not bulk up.

I need to lose sagging skin.

Is PhD for me?

Please & thanks

You need to engage in resistance/weight training – otherwise supplementing with a protein shake will not help build muscle.

Just purchased these shakes as a kind of kick start.

I have food issues, and believe me when I say I have tried every single ‘diet’ out there, and now after not being a club member of anywhere I am now heavier than when I gave birth to my daughter and my mind is a mess.

I don’t want to replace meals long term, just the odd one here or there or even replacing snacks and being more mindful of my eating and drinking overall.

I noticed on an earlier question you mentioned if replacing meals too often your body effectively shuts down and goes into shock.

My question is as someone who is fast approaching 40, what is a recommended amount of calories to be taking onboard?

Currently I exercise by skating 2/3 times a week and the odd gym session with weights when I have time.

There is so much info out there and my poor head is filled with so much misinformation on nutrition.

I’m desperate to get out of this awful cycle.

Personally, I would advise not getting too hung up on calorie counting or sticking to diets.

Just keep it simple – have three wholesome meals a day with lots of meat, poultry, fish, fruit and veg.

Avoid snacking on rubbish, drink lots of water, exercise regularly, and get 8-9 hours sleep every night.

It’s really as simple as that – you just need to be consistent!

I’ve just bought PhD Diet Whey (Belgian Chocolate flavour) to help me get a protein rich start to my day when I’m short on time.

Tried it for the first time today and not liking how sweet it tastes.

Any suggestions on how to cut the sweetness?

Add more milk/water to dilute it further.

Failing that, try a different flavour.

I’ve just picked up some of this stuff, haven’t tried it yet.

My question to you sir is this –

In times of desperation, what exactly is wrong with masturbating over trees?

Is there a law against it or is it simply frowned upon?

Many thanks

If you’re going to do it, at least choose something elegant like a Cherry Blossom or a mighty Oak.

It sells in Cosco with a shaker for £30 no vat.

Gotta love Cosco!

It’s been 2 days since I’ve started this protein shake.

I took the vanilla flavour as this was recommended.

It tastes amazing.

By the way I would like your opinion about my meals.

Breakfast I have the shake with fruits.

Lunch big plate of salad with something (like pasta with pesto and cheese only size of my hand).

And the evening maybe a fruit again with the shake or salad and the shake.

Gym I will start in 2 days, I was thinking to try to go 3-4 times per week if it’s possible because I don’t have a standard schedule.

Should I try to go more?

Btw apart from the vanilla do you suggest any other flavours?

Because I will get bored.

Can you tell me a little more about your goals first, what are you trying to achieve?

I could find it in Asda yesterday for £17.29/kg!!

Good luck!!

Thanks for letting us know!

Holland and Barrett doing a 1kg bag £15 also matrix stores!!!

Hi Henry, I’ve had a couple of packets of PHD Whey Protein in my cupboard for about a year but when I went to make a shake this morning, I noticed lots of black bits in it and it didn’t smell as good as it did when first opened.

The expiry date isn’t until October 2017.

I have the chocolate and vanilla flavours.

Do you think this is still okay to use?

I’m not sure if the black bits are weevils.

If it fails the smell/taste test I would personally bin it.

You’ve done the best informing report yet about this magnificent product it helped me a lot but had to stop during pregnancy because I read it’s not safe.

Do you have any idea if it’s OK whilst breastfeeding then?

I don’t see why it wouldn’t be OK, but consult a doctor if you’re worried.

Love it… been on this for 16 days whilst remaining quite active and before I’ve actually started proper jogging, hiit and training.

I use it twice a day with one main meal have lost shit loads of weight already.

Don’t feel hungry… love it!

Great to hear it, feel free to get in touch if you have any questions!

Hi how long in total did you use it as a meal replacement and what were your results 🙂

I am 63 and bought this to aid losing weight after reading this I think i bought wrong product.

I am on my feet all morning as a cook and are going to start on my rowing machine is this enough to lose weight?

To lose weight you simply need to be consuming less calories than you burn.

If this is adding calories to your diet, it will do the opposite…

Hi, I’m a keen cyclist & have been recommended PHD Diet Whey to supplement the calorie burn.

I don’t actually want to lose too much weight.

Ideally maximise the muscle building.

Not going for the Froome physique… more a sprinter physique.

Does this fit the bill?

Anything that keeps you away from a caloric deficit will stop you from losing weight.

If this shake is convenient for you, go for it.

And if you want to maximise muscle gain, lift weights.

First class Henry! Cheers.

No worries, glad to help.

This is by far one of the best reviews I’ve read.

You are wasted peanut shovelling and should write a book.

Loved the review!!

I bought 1 kilo bags from Holland & Barrett in the following flavours (which I believe is currently the full set!) for £13.49 per bag less 20% discount.

I haven’t tried them all yet but some of these flavours make me salivate before I’ve even tried them!

I think I’ve got a protein shake fetish, although there are worse things to have a fetish about.

I’ve lost five kilos this year, and the annoying bit of fat around my mid section is now just a memory.

I would put my progress down to weights, cardio and counting calories via my fitbit, and not down to phd whey protein, but I like to think that it has definitely helped along the line.

I used to add it to soya milk but that became expensive and finicky, so now I just add it to cold water.

The first two or three gulps were less creamy to the taste, as you would expect, but since then I’ve never looked back.

TBH like many on here I just love the taste!

PhD Nutrition Diet Whey Review (updated for 2019)

08/03/2017 By Stacey Teale, Site Editor

Its blend of whey protein concentrate, soya protein isolate and milk protein concentrate, along with waxy barley flour, is designed to help you build muscle, boost energy, provide the body with much-needed vitamins and help with weight management.

<<< SPECIAL: See our Best Protein Powders to Buy in the UK in 2020 >>>

It contains 91 calories per 25g serving and is low in sugar, fat and salt. A bigger serving (two scoops) should give you about 34g of protein alongside 5.5g of carbohydrates and 2.5g sugar. Different flavours may have slightly different nutritional values.

It also contains additional ingredients such as green tea extract, L-Carnitine and CLA, among others, to encourage weight loss, so let’s have a look at what they do and if they work…

Ingredients

Whey protein concentrate.

Whey protein is a popular source of protein, absorbed much quicker than other alternative sources. It can stimulate protein synthesis – the act of promoting muscle growth – in just 40 minutes after ingestion. Protein also helps the body to recover quicker after intense exercise. The whey protein here contains 3.3g of BCAA (Branched Chain Amino Acids), the amino acids responsible for synthesis, per 25g serving.

Whey protein concentrate is a cheaper option than whey isolate or hydrolysate, but PhD Nutrition Diet Whey includes two further protein sources as well, such as…

Milk Protein Concentrate

Milk Protein Concentrate (MPC), mostly micellar casein, may act as an appetite suppressor thanks to its slow-releasing protein which continues to release amino acids over time. A 2013 research paper also pointed out that the consumption of dairy products is linked to a decrease in metabolic-related diseases. Poor metabolic health is often linked to obesity or being overweight.

Soya Protein Isolate

A third form of protein, Soya Protein Isolate (SPI) usually contains a minimum protein content of 90% thanks to its highly purified form. It is believed to provide the full range of amino acids needed by the human body.

All three of the proteins mentioned above have varying digestion rates, potentially helping to lengthen the period of protein synthesis.

Fat Reduced Cocoa Powder

Now we come to the potential weight loss ingredients. Cocoa powder may be useful in weight loss, thanks to its flavonoids which can protect cells from free radicals. It is included here to protect against damage caused to proteins and enzymes. A Japanese study reporting in Nutrition (May 2005) also discovered that cocoa powder has the ability to interfere with the body’s ability to change dietary fat into fatty tissue. A three week test in rats found the cocoa powder group had significantly lower body fat than the control group.

Waxy Barley Flour

A type of starch, wax barley is commonly found in plants and can help to store energy. Barley can also decrease the level of glucose absorption in the blood, thus helping blood sugar levels to become more stable. Barley is also described as a main source of nutrients and fibre needed for a healthy diet. Studies also show that consuming barley can be an effective way to reduce LDL cholesterol, the bad cholesterol, in the body. LDL is responsible for cholesterol build up and potential blockage of the arteries.

Golden Brown Flaxseed Powder

Flaxseeds are a primary source of dietary fibre which, if taken before a meal, may act as an appetite suppressor. Studies have shown that it may also be able to lower ‘bad’ LDL cholesterol.

A powdered version of Conjugated Linoleic Acid, CLA may help people to lose weight by reducing fatty deposits in the body and boosting immunity. A meta-analysis of various studies showed that while CLA is more effective in animals, consuming approximately 3.2g a day of CLA could also help humans enjoy a ‘modest’ fat loss. Unfortunately, PhD Nutrition just contains 375mg of CLA per 25g serving.

Green Tea Extract

Green tea extract is a popular ingredient in fat burners thanks to its natural antioxidants, known as catechins, and small amount of caffeine which both help to speed up the metabolism. This thermogenic process helps the body to potentially burn more calories.

One research study , for instance, showed that people taking green tea extract lost 7.7% of fat around the abdominal area, as opposed to those taking a placebo (only lost 0.3%).

The effectiveness of green tea has long been recognised in weight loss circles.

It is low in fat, sugar and salt with just 91 calories per 25g serving.
Green tea is a well-known thermogenic agent, popular in weight loss circles because of its proven success.
Available in a wide range of flavours.
Vegetarian-friendly.
It is also halal, GMO-free and palm oil-free.
Contact details for PhD Nutrition are easy to find and you can telephone, speak to them online or fax.
PHD Nutrition is very upfront about its nutritional values.
It has gained a 4.1 rating out of 5 on Amazon UK at the time of writing (late 2018/2019)
While research into some of its ingredients is available, there have been no clinical studies done on PhD Nutrition Diet Whey as a whole. As a result, it is impossible to prove how successful it may be.
Some of the individual ingredients may cause side effects
Some customers have complained about the flavours, describing them as very sweet. Even those customers who like the taste admit the shake is grainy, probably as a result of the flaxseed included.
The mix is also described as quite thick and heavy, so is best avoided before a workout.
PhD Nutrition recommends one scoop of protein powder (25g) for a ‘normal’ shake, or two scoops to super-size it. If you opt for just one scoop, however, you will only consume 17g of protein, which is pretty low for a protein shake (experts recommend at least 20-25g of protein in a shake). Two scoops will give you about 35g of protein though that’s still lower than some of Diet Whey’s competitors, such as LA Muscle LA Whey Gold which gives nearly 50g of protein per serving (granted, per serving is 70g).
Can be quite pricey unless you can find a discount or special offer.

Who Takes It

PhD Nutrition states that its Diet Whey is suitable for men and women following a weight management nutrition plan, gym goers aiming to control calorie intake and lose body fat, and anyone wanting a high protein supplement. It is also suitable for anyone looking to replace a meal with a high protein and low sugar, fat and carb shake.

Safety/ Side Effects

There has been no clinical research done on PhD Nutrition Diet Whey as a whole, therefore there are few records of significant side effects. However, some of the individual ingredients in Diet Whey may cause side effects ranging from headaches, fatigue, irritability and stomach troubles. A common side effect of regularly ingesting protein shakes is also gas and tummy troubles.

How to Take It

For one normal serving, add 25g (one scoop of powder) to 175ml of ice cold water and shake or blend. To super-size it, add two scoops of powder to double the water. Note that some customers advocate using more water than recommended or even mixing it with milk to thin out or improve the taste. Of course, adding milk will increase the calorie count.

It is fair to say that the protein and amino acids in PhD Nutrition Diet Whey should be able to help with muscle building and potentially muscle repair, though a 25g serving is very low in protein and should be double sized if you want to build muscle and not gain fat.

Green tea is also a well-known weight loss ingredient and may help to boost the metabolism. PhD Nutrition Diet Whey’s 100mg of green tea per 25g serving is unlikely to be enough to encourage weight loss, however. Experts theorise that you need to drink approximately two to three cups of green tea with between 120-320mg of catechins in each cup to have any effect. So it’s probably worth having two scoops for the green tea as well.

Overall, there’s very little clinical evidence – and none given on the official website – to support the use of Diet Whey as an effective weight-loss aid. If you’re primarily looking to drop fat, you may be better off using a weight loss supplement or diet shake backed by solid clinical research.

Here’s where it gets interesting, however. Despite all of the above, you can’t ignore the fact that more than 3,000 customer reviews on Amazon UK give PhD Nutrition Diet Whey a 4.1 out of 5 star rating. It’s obviously working for a lot of people, with many claiming to be losing weight. Many recommend it as an appetite suppressant in particular.

If you want to gain muscle while also losing fat, PhD Nutrition Diet whey could potentially do the job for you, alongside a healthy lifestyle. If nothing else, it may help you control your cravings, thanks to the flaxseed. It’s just a shame the protein count is so low.

How to Get the Most Out of Phd Diet Whey Supplements

Whey protein has become a popular supplement for body builders and anyone who wants to get rid of fat and turn it into muscle. The protein itself, which comes from cow’s milk and was once was regarded as useless by cheese farmers, has now been discovered to provide so many different benefits to the human body; it’s a vital component to any compositional training and has become a popular supplement for so many people.

PHD Diet Whey for Fat Loss

So what exactly is it? And how does it work? As one of the two proteins found in cow’s milk, whey is actually very common and most people have had whey in their diet all their lives. Whey provides essential amino acids, which are the body’s building blocks for muscle tissue, energy production, brain metabolism, cardiovascular function, immune system function and more.

PHD Diet Whey is designed for anyone looking to lose weight as well as maintaining muscle mass . As well as a high protein blend, Diet Whey from PHD also contains barley starch as a source of healthy complex carbs.

If you want to make sure you get the most out of your diet whey protein, here’s how:

Use it as a meal replacement – whey protein should be a part of a healthy and balanced diet. It is designed to be a supplement to healthy eating and living but can be used as a meal replacement at your discretion. A great way of using this meal replacement is to choose one meal a day to replace it with.
Have a healthy eating plan – if you are wanting to get rid of fat and/or build muscle, it’s important to understand that whey protein alone won’t help you. It is a supplement and that means you must have a healthy eating plan in place. Include 5-a-day of fruit and veg and ensure you have protein, the right amount of carbs, fibre and all the essential vitamins in your diet.
Use whey post workout – the protein is designed to be absorbed quickly by your body and the best time for this to happen is after your workout session. After working out, your body provides the best structural positioning for absorption.
Build your workout plan – whey protein should be incorporated into a healthy living and exercise plan. Not only should you review your diet regularly but you should have a workout schedule in place if you want to see results. The most important thing about losing weight is to keep momentum and keep going.

When is the best time to drink PHD Diet Whey Protein

I am looking to burn fat and gain muscle during my sports off season. I gym about 3 times a week, and take PHD diet whey.

I have one in the morning and one after going to the gym in the evening.

When is the best time to take another shake on non-gym days?

1 Why do you think the timing matters on non-gym days? – user3085 Commented Aug 12, 2012 at 21:05
because the aim of this particular shake is to keep up the metabolism rate and acts as a meal replacement. Should this replace a mid afternoon snack, an evening meal, or a later afternoon meal? (based on 6 small meals a day) – Graeme Hutchison Commented Aug 15, 2012 at 23:18
2 Unless you are specifically calorie or protein deficient, I'd advise eating real food instead, especially on off days. – JohnP ♦ Commented Sep 13, 2012 at 18:22
1 @GraemeHutchison nutrition timing is not that important except for the protein source around workouts (as that anabolic window opens up). Take it whenever you feel like on non-gym days would be my recommendation. – Mike S Commented Sep 14, 2012 at 6:02
3 @GraemeHutchison - Actually, yes, I am helping. You just don't like the answer. There is more to real food than there is in a protein supplement, plus you have to worry about the actual absorption and utilization in the absence of other nutrients/vitamins/minerals. – JohnP ♦ Commented Oct 29, 2012 at 23:17

I don't understand why all the answers saying timing doesn't matter are being downvoted.

There is no link between time of protein ingestion in relation to working out that has any substantial effect. Please see this paper.

1 Probably because they are low quality, one liner answers. Also, if you could summarize/recap the main points of the study, it would help your answer stay valid if the link ever breaks. – JohnP ♦ Commented Jul 17, 2015 at 21:29

You drink protein shake to complement your protein intake, regardless of training days or times, unless you are very experienced timing doesn't really matter.

How did get downgraded? timing matters least when intake isn't measured. especially for beginners – Greg Mikolap Commented Jul 20, 2015 at 19:20

I think that you are absolutely on the right track as far as when you are taking them on your workout days.

As far as non workout days go, the best thing to do, IMO, is to have one in the morning within a half hour of waking up and if you want a second one, go for it. I honestly don't think the timing is that important. You really need to listen to what your body wants if you are craving more food. DO you want carbs, sugar, etc... There are healthy foods that will solve those needs. If your body wants protein have another shake. I don't think that you will be getting full benefits from a nutritional shake just by taking it because you think you need to. They are best in the morning and after working out.

2 I wonder how the body tells someone they are craving for some specific nutrient. – Baarn Commented Oct 29, 2012 at 21:40
You know that is one that I can't answer but often times when i am craving carbs or sugar, I will have some fruit or broccoli (for example) instead of bread, or candy, your body naturally wants fat and sugar you just have to find the healthy substitutes – Dean Karasinski Commented Oct 29, 2012 at 22:54
1 -1 @DeanKarasinski All the overweight people crave nutrient dense fatty sugary food because it is an addiction like a drug. Telling someone to listen to their cravings is ridiculous advice. Face palm! – Mike S Commented Oct 29, 2012 at 23:47
If you read what I actually wrote, you need to feed your body what it wants. It tells you for a reason. If you want fat east some almonds, if you want sugar eat some fruit. Dont go eat a stick of butter and a donut. You HAVE to listen to your body or you will never make on your diet. – Dean Karasinski Commented Oct 31, 2012 at 17:04

STATEMENT OF AUTHORSHIP

Associated Data

Background & aims:.

Weight loss in older adults enhances physical function, but may lead to sarcopenia and osteoporosis. Whey protein is a low cost rich source of essential amino acids, may improve physical function. We evaluated the feasibility and acceptability of consuming whey protein in the context of a weight-loss intervention in older adults with obesity.

A 12-week pilot feasibility, non-randomized weight loss study of 28 older adults was conducted, consisting of individualized, weekly dietitian visits with twice weekly physical therapist-led group strengthening classes. Half consumed whey protein, three times weekly, following exercise. Preliminary efficacy measures of body composition, sit-to-stand, 6-minute walk and grip strength and subjective measures of self-reported health and function were also evaluated.

Of the 37 enrolled, 28 completed the study (50% in the protein group). Attendance rates for protein vs. non-protein groups were 89.9±11.1% vs. 95.6±3.4% (p=0.08). Protein consumption was high in those attending classes (90.3%) as was compliance at home (82.6%). Whey was pleasant (67.3±22.1, range 30-100, above average), had little aftertaste, and was neither salty or sticky. All were compliant (0.64±0.84, range 0-5, low = higher compliance). Both groups lost significant weight (protein vs. no protein, −3.45±2.86 vs. −5.79±3.08, p=0.47); Sit-to-stand, six-minute walk, and gait speed were no different, grip strength was improved in the protein compared to the non-protein group (−2.63 kg vs. 4.29 kg; p<0.001).

Conclusions:

Our results suggest that whey protein is a low-cost and readily available nutritional supplement that can be integrated into a weight loss intervention.

Introduction

The growing obesity epidemic affects over 40% of adults 65 years and older[ 1 ], and is associated with a higher risk of institutionalization[ 2 ], mortality[ 3 ], and costs[ 4 ]. Health promotion interventions in older adults, including weight loss, can enhance physical function and quality of life[ 5 ], but should be guided cautiously to prevent sarcopenia and osteoporosis[ 6 ] particularly in vulnerable older adults[ 7 ]. Energy deficits created by caloric reduction can lead to a downregulation of muscle protein synthesis and an increase in muscle proteolysis. This can contribute to reduced skeletal muscle mass which consequently may affect strength[ 8 ]. Sarcopenia developed during weight loss can threaten physical function and long-term health[ 9 ] but may be partially mitigated by increasing protein intake with a supplement. Additional protein may restore optimal anabolic signaling in aging.[ 10 , 11 ] In addition, there may be an improvement in muscle parameters during resistance training.[ 12 ] through increased muscle protein synthesis.[ 13 ]

Whey protein, a milk-derived protein, contains essential amino acids and high quantities of branched-chain amino acids.[ 14 ] As a fast-acting protein, whey can stimulate post-prandial muscle protein synthesis more efficiently through faster digestion and quicker absorption[ 15 ] compared to casein or soy.[ 14 ] Increasing daily protein intake has been recommended for older adults, and may mitigate sarcopenia during weight-loss efforts in older adults.[ 16 ] Protein supplementation has been purported to enhance muscle mass and strength within the context of weight loss interventions.[ 17 ] It has been hypothesized that this may indeed improve physical function and preserve changes in body composition in behavior-based obesity treatments.[ 18 ]

Whey supplementation comes in tablet, liquid, or powder-based formulations. Older adults often are prescribed supplementation during unintentional weight loss or following an acute illness.[ 19 ] Palatability of supplementation is a key driver of compliance.[ 20 ] Hence, it is critical that the supplement within the context of a weight loss intervention is feasible, tolerable, and patient’s exhibit compliance prior to a large-scale clinical trial. Only then can the effectiveness of high-dose whey protein (>20g) be evaluated whether it can attenuate muscle catabolism. Our objective was: a) to ascertain the feasibility of providing whey protein supplementation during a 12-week weight loss intervention in older adults with obesity; b) determine the acceptability of consuming the supplement; and c) evaluate in an exploratory manner whether there were preliminary signals of efficacy between our comparison groups. This information can provide preliminary data prior to investing resources in conducting a large-scale trial evaluating the efficacy of such a supplement on changes in body composition or physical function observed with weight loss.

MATERIALS & METHODS

Study design and setting.

We conducted a non-randomized study of older adults with obesity (body mass index [BMI] ≥30 kg/m 2 ) residing in rural Northern New England. Dartmouth-Hitchcock is an academic medical center located on the New Hampshire and Vermont border, serving >1.5 million patients yearly. Study activities took place at a community-based aging center serving older adults. The study was approved by the Committee for the Protection of Human Subjects at Dartmouth College, the Dartmouth-Hitchcock Institutional Review Board, and the Institutional Review Board at the University of North Carolina at Chapel Hill, and registered on clinicaltrials.gov ( NCT#03104192 ). Informed consent was obtained for experimentation with human subjects.

Intervention

A series of studies consisted of 6-8 participants at each time were conducted over an 18-month period. Briefly, each set of participants received a 12-week, on-site, diet and exercise intervention consisting of individual, weekly, 30-minute registered dietitian nutrition sessions, and twice-weekly, 75-minute physical therapist-based group exercise sessions based on the recommendations of the American College of Sports Medicine.[ 21 ] An individualized program consisting of resistance, flexibility and balance exercise plans were developed as previously described [ 22 , 23 ]. All participants were provided a wearable fitness device (Fitbit Flex 2) and a Samsung Galaxy Tab A tablet to permit remote monitoring of their aerobic activity. Participants were evaluated weekly as to whether they completed a third session of resistance exercises weekly.

Recruitment

Participants were recruited from both primary care clinics and community settings as previously described.[ 22 ] Adults aged ≥ 65 years with a BMI ≥ 30kg/m 2 were eligible, but excluded if there was an electronic medical record diagnosis of dementia, uncontrolled psychiatric illness, bariatric surgery, life-threatening or end-of-life illness, participation in other weight-loss endeavors, on obesogenic medications, advanced systemic illness, or an intentional weight loss of ≥5% in the past six months. Information was also obtained from self-reported survey questionnaires. Participants required a score of ≥3 on the Callahan Cognitive questionnaire[ 24 ], and scores of ≥71.2 and ≥56.4 on the Functional Status questionnaire for basic and instrumental activities of daily living[ 25 ]. All 37 participants consented were compensated $25 for each assessment completed, of which 28 completed the intervention.

Whey Protein Supplementation

Half of the participants (n=14) were asked to consume one serving of a whey-protein based supplement (Thorne Whey Protein Isolate, Thorne Research, Dover, ID), consisting of a choice of 27g (vanilla) or 29g (chocolate) of whey, three times per week after each exercise session. The manufacturer’s label indicated 2.2g of leucine per serving. Two servings were consumed under direct supervision by the physical therapists during the in-person sessions, while the third dose was self-administered at home. The powder was constituted in 8 oz of water and consumed within 30 min of their exercise session. Participants were provided the protein on-site from the same flavored container; each was given an individual protein container for home use. Compliance was monitored using a self-report diary. No sham protein was provided to the non-protein group. The research team conducted an analysis using mass spectroscopy of the total protein and amino acid composition of all samples (MToZ-biolabs, Boston, MA). A standard protocol evaluated a branch chain amino acid analysis. [ 14 , 26 ]

Study Outcomes

Our primary outcome was the feasibility and acceptability of whey protein consumption in the whey protein group. Drink characteristics of the whey supplement were rated on a 100-mm visual analogue scale[ 27 ], with anchors placed at 0 mm (not at all) and 100mm (extremely/extreme). Select questions from the Moriskey Medication Adherence Scale[ 28 ] scale were rated on a 0-5 Likert scale (low to high). Semi-structured interviews were related to the protein supplement and conducted by the lead author and coded independently by members of the team (See Supplementary Appendix #1 ). The purpose of these interviews was to gain insights into the consumption of the protein as part of this intervention.

Preliminary efficacy measures were based on physical function, weight and body composition measures using subjective and objective measures. Weight was measured using an A+D scale; height was assessed using a stadiometer. BMI was calculated using Quetelet’s formula. Waist circumference was measured at the level of the iliac crest using a standard tape measure. Physical function measures included gait speed, 5-times sit-to-stand test, and 6-minute walk test. A 5-m course permitted assessment of gait speed, with an acceleration/deceleration component. Three trials of grip strength in each had was measured using a JAMAR dynamometer. The maximum strength was used in the analysis. A 5-times sit-to-stand test was conducted using a standard chair with a back. Participants performed the test with their arms folded and their buttocks hitting the chair on each repetition. Surveys were administered using RedCAP with data double verified. The Patient Reported Outcome Measurement Information System (PROMIS) Global short form 10 function (physical and mental health) and the Function component of the Late-life Function and Disability Instrument were also posed to participants as in our previous studies[ 22 , 23 ].

Body composition, including percent body and visceral fat, was assessed using the Seca mBCA bioelectrical impedance analyzer (Hamburg, Germany). This eight-point method uses a flow of low alternating current. Participants’ physical activity level (on 5 levels) was entered and they then stood barefoot for 20 seconds holding the hand electrodes. Appendicular lean mass (ALM) was defined as the sum of the upper and lower extremities and then normalized for both BMI and height (m 2 ).

Statistical Analysis

A priori , we defined successful retention as a dropout rate <20%, and attendance rate of >75% of sessions as acceptable. Continuous variables are presented as means (standard deviation) or counts (percent). Paired t-tests compared pre/post characteristics within groups. We compared the pre-post change in each metric between participants in the whey protein group vs. the non-whey group using an unpaired t-test with unequal variances for continuous values, or chi-square for categorical variables. We used a mixed effects model clustering on the individual to examine the impact that protein supplementation had on the change in each metric of interest as an outcome while adjusting for baseline grip strength. The analysis was based on complete case ascertainment. A sensitivity analysis was also conducted adjusting for baseline grip strength. All quantitative analyses were conducted using R v3.6 ( www.R-project.org ). Interviews were transcribed using a commercial transcription service. Transcripts were read and open coding was conducted, a process of labeling portions of text to identify ideas and concepts. Codes were inductively- and deductively evaluated. A query tool retrieved text by code, which were reviewed for content, relevance and prevalence of themes. Qualitative data from the semi-structured interviews were evaluated using Dedoose . A p-value <0.05 was considered statistically significant.

There were 37 participants enrolled in both arms with 28 completing the study ( Table 1 ). Other than smoking status, there were no differences in demographics between the protein vs. non-protein groups. In the protein (whey) group, our completion rate was 14/17 (82.4%). Mean attendance rates were 89.9±11.1% vs. 95.6±3.4% (p=0.08), in the protein vs. non-protein groups. Protein consumption was high in those attending classes (90.3%) as was self-report compliance of whey at home (82.6%). Eleven participants consumed chocolate whey and 6 chose vanilla whey. Mean total protein (g) in each serving was no different (9.51±1.41 vs. 9.94±0.75, p=0.70), and mean leucine concentration between chocolate and vanilla was statistically different (2.49±0.29 vs. 2.25±0.07, p=0.02). Table 2 highlights the questions on drink characteristics scale. The reconstituted whey drink was pleasant (67.3±22.1, range 30-100, interpretation of above average), had little aftertaste, and was neither salty, creamy thick, sticky or fruity. Participants exhibited good compliance with consuming the drink at home as they rated forgetting to take their whey at home as low (0.64±0.84, range 0-5, low to high). The protein was not perceived as an inconvenience to consume (0.57±1.16).

Key qualitative themes are represented in Table 3 . Participants did not have any pre-conceived expectations of the suitability of the protein supplement and were unsure whether the protein helped them. It tasted better than expected and would consider using it again. All participants believed protein was critical in weight management and in preserving muscle. Reportedly, participants stated they consumed the whey on their non-person days as a result of their commitment to the study.

Select Quotations of The Whey Protein Supplement

Domain/ Theme	Representative Quote
	"Yes, it did because I used to take them on and off before and it does fill me up and when I'm on the run, it works out great."
	"I kind of thought maybe they would help. I wanted to see, and see if I noticed any difference. But of course it's hard to tell when you're increasing your exercise and doing other things, what's really helping. But it didn't hurt me any."
	"I thought it was great, the flavor of both. I had chocolate but I had tried the vanilla, they were both good. As long as it's cold and well-mixed I didn't find a problem with it whatsoever."
	"At first, I thought it tasted horrible. But then, I also discovered that you have to stir it quite a bit to get it so you don't have those little lumpy things. But once you got used to remembering that you had to take it each time after you exercise, it was okay."
	"I think some of them are helpful. In particular, when I wasn't eating as well as I am now. I think they were good, to make up for things that I wasn't getting.
	"Well I know that it's extremely important and it tells in the individual diet how much protein we should get per day. I've truly stuck with the plan too and done everything I should."

Table 4 reflects that both groups lost a significant amount of weight over time (protein vs. no protein, −3.45±2.86 vs. −5.79±3.08, p=0.47); however, those in the protein group lost less weight. No differences were observed in waist circumference. Neither group lost significant appendicular lean mass. In protein participants, there were no changes in body or visceral fat mass; between groups, this was statistically different. While both groups improved their sit-to-stand times, six-minute walk, and gait speed, grip strength was significantly improved in those consuming whey as compared to the non-protein group (−2.63 kg vs. 4.29 kg; p<0.001). Pre/post subjective measures of health and function improved in both groups, but no different from each other. We found minimal differences after adjusting for baseline grip strength.

This study evaluating whey protein supplementation demonstrated its feasibility and acceptability. Using quantitative and qualitative data, we confirmed in a sample of 14 participants, that this supplement can be integrated in future health service interventions. Importantly, we also demonstrated preliminary efficacy of physical function measures.

Our data provides formative information to set the stage for a future trial. First, we had minimal number of dropouts in our protein cohort; this suggests that the supplement would not impact our approach and that interventionists could potentially focus on delivering a weight loss intervention rather than focusing on its palatability. Hence, we feel confident that we can proceed with a larger scale trial. Second, we have documented patient acceptability using standardized scales. Third, while whey protein supplementation physiologically is suggestive of maintaining muscle mass and strength in older adults, our results demonstrate a maintenance of appendicular lean mass. These findings approximated those found by others; however, whey was administered in exercise-only studies (following exercise) but had a higher protein dose (40g/day)[ 29 ] or only on exercise days[ 30 ] (e.g, three times weekly). Fourth, the added caloric intake from whey protein may blunt the degree of weight loss; it is unclear whether protein impacts satiety or meal consumption. Such findings need to be confirmed in larger scale studies.

A major concern at the beginning of the study was whether protein supplementation would be acceptable to participants. Our results suggest excellent compliance and tolerability which is similar to what was observed by others[ 27 , 31 ]. Palatability is a key component for any type of intervention in that unpalatable items will lead to non-compliance. Our quantitative data also confirmed the quantitative findings. We believe that future studies should be generally confident of its acceptability.

Previous studies have demonstrated that multicomponent interventions consisting of caloric restriction and resistance/aerobic exercises have led to significant weight loss.[ 32 , 33 ] The addition of whey protein in our study led to less weight loss and minimal changes in body or visceral fat. A number of reasons could explain these findings. First, the duration of treatment was short. Studies whose duration is three months have shown fewer changes in body composition[ 34 ]. Other studies last up to six months that demonstrated maintained muscle mass with accompanied improvements in muscle protein synthesis and muscle quality in the vastis lateralis[ 35 ], or reductions in intramuscular fat.[ 36 ] Second, it is unclear whether the functional status of our study population may have impacted our results. While we did not specifically incorporate the Short Physical Performance Battery as an outcome measure, our participants had a rather high level of physical function. Other authors have evaluated the impact of protein supplementation on higher risk, and more functionally impaired participants[ 37 , 38 ]; yet these authors found conflicting findings on physical function using protein. Yet, our findings did not change after adjusting for baseline grip strength. Third, this was a pilot study that was not powered to evaluate the effect of our efficacy outcomes, and only a fully powered randomized controlled trial could evaluate such. Last, while not a randomized trial, our results also corroborated a study demonstrating the limited impact of protein consumption with exercise.[ 39 ]

Our intervention findings did not find any significant changes between groups over time between protein vs. non-protein groups on key measures of 5-times sit-to-stand, 6-minute walk and gait speed. The protein group had improvements in grip strength, but this was not evident in the non-protein group. The minimal differences in body composition between remained, even after we conducted a sensitivity analysis adjusted for baseline grip strength. These results suggest that the increase in strength at follow-up may be due more to gains in neuromuscular function as a result of the upper body exercises. Another possibility may have been the small statistically significant differences observed in leucine composition (0.24 g) amongst the different flavors provided; whether this is clinically significant is unclear. Importantly, other amino acids may have contributed to the differences in overall protein composition, but future studies are needed to confirm such findings. While we adhered to the Office of Dietary Supplement Product Integrity guide, the protein composition is standardized to what is available commercially. A recent systematic review and perspective statement by the Obesity Society in fact highlighted product integrity concerns among the manufacturer’s claims [ 40 , 41 ]. Our findings may also provide additional insights in the timing of protein supplementation since we provided this following exercise. Whether consumption at other times and/or with increased amount, concentration and/or frequency require further examination.

In our study, we increased the protein allowance to 1.0–1.5 g/kg/day or a minimum of 20% of total caloric intake.[ 19 ] Older adults are at risk of developing anabolic resistance due to reduced post-prandial amino acid availability, muscle perfusion, and uptake, and digestive capacity from splanchnic sequestration of amino acids[ 20 ]. The lower degree of weight loss in the whey group suggested that caloric restriction may need to be even further limited than previously expected, despite structured meal plans and instructions to reduce caloric (mainly fat) intake on the days that they consumed the supplement.

This study had a number of limitations. First, it was non-randomized. While we compared the baseline characteristics of the two cohorts, unknown confounders may impact our primary and secondary outcomes. Second, this was a small study of 14 participants in each cohorts. Only larger, adequately powered studies could better evaluate efficacy of protein supplementation. Third, our cohort was homogeneous and the effects of protein supplementation may differ depending on ethnic and racial cohorts. Fourth, while we used commercially available standardized methods to evaluate the protein composition as a quality control measure, we did find some differences in leucine composition. Last, the study failed to evaluate perceived strength or measure lower extremity strength; hence, we were unable to mitigate the discrepancy between observed and subjective changes in strength itself. Since supplements are not regulated by the Food and Drug Administration, we could consider the protein itself as a pragmatic, commercially available product, and understand that there may be limitations in its response or action.

Implications and Future Directions

Strategies to optimize protein anabolism during weight loss are needed to prevent negative changes in body composition[ 5 , 6 ]. Our findings provide feasibility, acceptability and preliminary effectiveness data to conduct a large scale, adequately powered, randomized controlled trial comparing the effectiveness of a whey protein supplement within the context of a weight loss intervention in older adults. In such a trial, we would need to better oversee caloric restriction in the protein supplement group, extend the duration of the trial, and consider varying the protein supplement administration. If caloric intake was truly an issue, varying the administration schedule (e.g., twice weekly), timing (before exercise vs. after exercise), or amount (1/2 a serving vs. a full serving) could be considered. Importantly, whey did not have a negative impact on any of our subjective functional measures, nor on appendicular lean mass. Furthermore, emerging data suggests that lean mass is less important than loss of muscle strength and hence our findings confirm this potential finding.

Weight-loss success depends on eating more protein, fiber while limiting calories

Flexibility and personalization boost adherance to diet.

Participants on a self-directed dietary education program who had the greatest success at losing weight across a 25-month period consumed greater amounts of protein and fiber, a study found. Personalization and flexibility also were key in creating plans that dieters could adhere to over time.

At the one-year mark, successful dieters (41% of participants) had lost 12.9% of their body weight, compared with the remainder of the study sample, who lost slightly more than 2% of their starting weight, according to a paper on the study published in Obesity Science and Practice.

The dieters were participants in the Individualized Diet Improvement Program, which uses data visualization tools and intensive dietary education sessions to increase dieters' knowledge of key nutrients, enabling them to create a personalized, safe and effective weight-loss plan, said Manabu T. Nakamura, a professor of nutrition at the University of Illinois Urbana-Champaign and the leader of the research.

"Flexibility and personalization are key in creating programs that optimize dieters' success at losing weight and keeping it off," Nakamura said. "Sustainable dietary change, which varies from person to person, must be achieved to maintain a healthy weight. The iDip approach allows participants to experiment with various dietary iterations, and the knowledge and skills they develop while losing weight serve as the foundation for sustainable maintenance."

The pillars of iDip are increasing protein and fiber consumption along with consuming 1,500 calories or less daily.

Based on the dietary guidelines issued by the Institutes of Medicine, the iDip team created a one-of-a-kind, two-dimensional quantitative data visualization tool that plots foods' protein and fiber densities per calorie and provides a target range for each meal. Starting with foods they habitually ate, the dieters created an individualized plan, increasing their protein intake to about 80 grams and their fiber intake to about 20 grams daily.

In tracking the participants' eating habits and their weights with Wi-Fi enabled scales, the team found strong inverse correlations between the percentages of fiber and protein eaten and dieters' weight loss.

"The research strongly suggests that increasing protein and fiber intake while simultaneously reducing calories is required to optimize the safety and efficacy of weight loss diets," said first author and U. of I. alumna Mindy H. Lee, a then-graduate student and registered dietitian-nutritionist for the iDip program.

Nakamura said the preservation of lean mass is very important while losing weight, especially when using weight-loss drugs.

"Recently, the popularity of injectable weight loss medications has been increasing," Nakamura said. "However, using these medications when food intake is strongly limited will cause serious side effects of muscle and bone loss unless protein intake is increased during weight loss."

A total of 22 people who enrolled in the program completed it, including nine men and 13 women. Most of the dieters were between the ages of 30-64. Participants reported they had made two or more prior attempts to lose weight. They also had a variety of comorbidities -- 54% had high cholesterol, 50% had skeletal problems and 36% had hypertension and/or sleep apnea. Additionally, the dieters reported diagnoses of diabetes, nonalcoholic fatty liver disease, cancer and depression, according to the study.

The seven dieters who reported they had been diagnosed with depression lost significantly less weight -- about 2.4% of their starting weight compared with those without depression, who lost 8.39% of their initial weight. The team found that weight loss did not differ significantly among participants with other comorbidities, or between younger and older participants or between men and women.

Body composition analysis indicated that dieters maintained their lean body mass, losing an average of 7.1 kilograms of fat mass and minimal muscle mass at the six-month interval. Among those who lost greater than 5% of their starting weight, 78% of the weight they lost was fat, according to the study.

Overall, the participants reduced their fat mass from an average of 42.6 kilograms at the beginning of the program to 35.7 kilograms at the 15-month mark. Likewise, the dieters reduced their waists by about 7 centimeters at six months and by a total of 9 centimeters at 15 months, the team found.

In tracking dieters' protein and fiber intake, the team found a strong correlation between protein and fiber consumption and weight loss at three months and 12 months.

"The strong correlation suggests that participants who were able to develop sustainable dietary changes within the first three months kept losing weight in the subsequent months, whereas those who had difficulty implementing sustainable dietary patterns early on rarely succeeded in changing their diet in the later months," Nakamura said.

The team hypothesized that this correlation could also have been associated with some dieters' early weight loss success, which may have bolstered their motivation and adherence to their program.

Weight loss will come from eating more protein and fiber, new diet suggests

By StudyFinds Staff

Reviewed by Chris Melore

Research led by Manabu Nakamura, University of Illinois Urbana-Champaign

CHAMPAIGN, Ill. — What’s the secret to losing weight? Researchers at the University of Illinois believe the key is eating more protein and fiber, not less. Their novel dietary weight loss program shows promising results for some participants. However, it also highlights the challenges of sustainable weight loss.

The program, called the Individualized Diet Improvement Program (iDip), aims to help people lose weight by teaching them to make informed food choices rather than following strict diets or relying on pre-packaged meals. Along with focusing on protein and fiber, dieters also need to balance one other component — limiting their overall calories .

Weight loss does vary on iDip

The study, published in the journal Obesity Science & Practice , followed 22 participants over the course of a year. While the average weight loss was modest at about 6.5% of initial body weight, the results varied dramatically between individuals. Some participants achieved impressive weight loss of nearly 13% on average, while others lost little to no weight at all .

What sets this program apart is its focus on educating participants about nutrition and helping them develop skills to create their own personalized weight loss plans. Instead of prescribing a one-size-fits-all approach, iDip uses innovative tools to help people understand the nutritional content of foods and make better choices.

“Flexibility and personalization are key in creating programs that optimize dieters’ success at losing weight and keeping it off,” says Manabu Nakamura, a professor of nutrition at the University of Illinois Urbana-Champaign and the leader of the research, in a media release. “Sustainable dietary change, which varies from person to person, must be achieved to maintain a healthy weight . The iDip approach allows participants to experiment with various dietary iterations, and the knowledge and skills they develop while losing weight serve as the foundation for sustainable maintenance.”

Flexibility and personalization were key in creating self-directed diet plans that optimized participants’ weight loss success, according to nutrition professor Manabu Nakamura, left. His co-authors on a recent study about the program included, from left, graduate student Nouf Alfouzan; Catherine Applegate, a postdoctoral research associate at the Beckman Institute for Advanced Science and Technology; and John Erdman, professor emeritus of food science and human nutrition.

One key feature is the “Protein-Fiber plot,” a visual tool that displays the protein and fiber content of foods relative to their calories. This allows participants to easily compare different food options and choose those that are more nutritionally dense. The program also emphasizes increasing protein and fiber intake while reducing overall calories, a strategy backed by research for preserving muscle mass during weight loss.

“The research strongly suggests that increasing protein and fiber intake while simultaneously reducing calories is required to optimize the safety and efficacy of weight loss diets,” reports first author and U. of I. alumna Mindy H. Lee, a then-graduate student and registered dietitian-nutritionist for the iDip program.

No more calorie counting?

Another unique aspect is the use of a weekly weight chart based on daily weigh-ins rather than calorie counting. This helps participants visualize their progress and monitor their energy balance without the tedious task of logging every meal.

The study’s findings suggest that successful weight loss is closely tied to how well participants were able to implement the dietary changes taught in the program. Those who increased their protein and fiber intake relative to calories tended to lose more weight. Interestingly, weight loss in the first three months was strongly predictive of long-term success, highlighting the importance of early progress.

Nakamura adds that preserving lean mass is critical while losing weight, especially when using weight-loss drugs such as Ozempic . Simply put, keep eating your protein and fiber because these medications should not be taken on an empty stomach.

“Recently, the popularity of injectable weight loss medications has been increasing,” Nakamura concludes. “However, using these medications when food intake is strongly limited will cause serious side effects of muscle and bone loss unless protein intake is increased during weight loss.”

While the program showed promise for some, the wide variation in results underscores the complex nature of weight loss. Factors like depression, which was associated with less weight loss in this study, may play a role in outcomes. The researchers hope to refine the program based on these findings to improve its effectiveness for a broader range of people.

Paper Summary

Methodology.

The study enrolled 30 participants with a body mass index (BMI) of 25 or higher. Over the course of a year, participants attended 19 educational sessions and three individual advising meetings. They learned about nutrition, how to use the Protein-Fiber plot and strategies for making healthier food choices. Participants weighed themselves daily using Wi-Fi-enabled scales and submitted food records periodically. Body composition was measured at the beginning, middle, and end of the study.

Key Results

Of the 22 participants who completed the program, 9 achieved clinically significant weight loss of more than 5% of their initial body weight. These successful participants lost an average of 12.9% of their body weight, primarily from fat mass. The remaining 13 participants lost an average of only 2% of their body weight. Higher protein and fiber intake relative to calories was associated with greater weight loss throughout the study.

Study Limitations

The study had a small sample size and lacked a control group, making it difficult to draw definitive conclusions. The wide variation in results also limits the program’s reliability as a weight loss treatment. Additionally, the study only followed participants for one year, so the long-term sustainability of the weight loss is unknown.

Discussion & Takeaways

The iDip program shows potential as an alternative to traditional diets, especially for those who are able to successfully implement the dietary changes. The focus on education and personalization may help some people develop lasting healthy eating habits.

However, the varied results suggest that additional factors, such as mental health and individual circumstances, play a significant role in weight loss success. Future iterations of the program may need to address these factors to improve outcomes for a wider range of participants.
