Whey protein is a popular supplement for fitness and body building enthusiasts.

People who are dieting or getting shredded find the PhD diet whey replenishing almost like going for a retreat. PhD Diet Whey contains a protein blend of whey concentrate and soy protein isolate.

This 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, sort of a double-edged sword.

In this review we will look at the ingredients, benefits, side effects and customer reviews of this product.

What is Phd Diet Whey

PhD Nutrition Diet Whey Protein is a protein supplement from PhD Performance Nutrition that is designed to help with lean muscle and fat loss goals. This protein powder is a blend of whey concentrate and soy protein isolate.

PhD Diet Whey

PhD keeps the carbohydrates and calories low, but the protein high in a serving, the idea being to limit the amount fat while you’re working on toning your muscles.

The mix of ingredients keeps you feeling full throughout the day and helps to keep the pesky sugar cravings at bay.

PhD Performance Nutrition are also the producers of the well-known testosterone booster PhD Test Matrix. Phd Diet Whey Protein combines ingredients that target muscle building and toning with those that support increase in energy and fat loss. It is essentially a high-protein, low-calorie blended supplement designed to help people attain their fitness goals.

The isolate forms of protein are more expensive to produce due to the complexity of their production. A thorough filtering processes has to be done to remove the unwanted parts of the protein such as lactose, carbohydrates and fats. Both whey protein concentrate and soya protein isolate go through this process.

Soy protein isolate is known to be slower to digest than whey protein such that it will keep you fuller for longer and provide your muscles with a steady supply of protein over a longer time.

If you look at the ingredient list, you will find that there is some micellar casein protein included in the mix. This is a much slower releasing protein and will definitely keep you fuller for longer, making the PhD diet whey ideal for a meal replacing shake.

Phd Diet Whey Ingredients

PhD premium protein blend contains some great additional ingredients to aid weight-loss, such as 2,500mg of Conjugated Linoleic Acid (CLA) per 100g, green tea extract and acetyl L-carnitine and Milk Protein Concentrate (of which 80% is Micellar Casein). Let’s take a closer look at each of these and how they can help you lose weight.

Conjugated Linoleic Acid (CLA)

Conjugated Linoleic Acid (CLA) is a vital fatty acid that is essential for good health. CLA is believed to help decrease the amount of body fat while making you feel fuller for longer. Naturally, for example, you can get higher sources of CLA from grass fed beef over the grain fed counterpart. It is also a potent antioxidant, which can help prevent and fight against cancer. Natural is the best way, but sometimes that’s just not possible and that’s where a good quality supplement can help.

Green Tea Extract

Clinical studies suggest that there’s a relationship between green tea extract and weight loss. Green tea extract burns fats and boosts metabolism. Researchers point to the catechins in green tea as being responsible for its fat burning properties. Green tea extract contains around double the antioxidant-active ingredients than both vitamin C and vitamin E. When combined with caffeine it is reported to be most effective. Green tea is packed with powerful antioxidant, cancer-fighting goodness! Polyphenols are the main antioxidant found in green tea extract. These have been found to help prevent cancer.

Acetyl L-carnitine

Acetyl L-carnitine is a form of the carnitine amino acid. The short story about how it works is that this powerful amino acid helps to transport fat into the cells to be used as energy. For the carnitine to be most effective, you should ensure that you have sufficient intake of omega-3s in your diet or get a good quality supplement. It’s fitting, then, that PhD have thrown in some additional flaxseed which is high in omega-3 fatty acids.

The full ingredients list is PhD Premium Protein Blend (Whey Protein Concentrate (27%), Milk Protein Concentrate (26%) (of which 56% is Micellar Casein), Soya Protein Isolate), Cocoa Powder, Waxy Barley Flour, Golden Brown Flaxseed Powder, Reduced Fat Cocoa Powder, Thickeners (Acacia Gum, Guar Gum, Xanthan Gum), Flavouring, CLA Powder (contains Milk Protein, Lecithin, Vitamin E) Acetyl L-Carnitine, Green Tea Extract, Sodium Chloride, Sweetener (Sucralose)

Phd diet whey 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 Strawberry, Belgian Chocolate, Banana, White Chocolate, Chocolate Mint, Lemon & Blueberry, Salted Caramel, Chocolate Peanut and Cookies & Cream.

PhD Belgian Chocolate

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

Blending it with semi-skimmed milk (always tastes much, much better than with water) and a banana or some other frozen fruit will give a refreshing and tasty protein shake.

Who Is PhD Nutrition Diet Whey Protein Best For?

PhD Diet Whey Protein Powder Customer Reviews

We’re all different, but it’s helpful to hear what others who are on the diet whey protein supplement have to say about their experience.

Some customers had this to say;

Having tried various protein powders, I decided to give this one a try. It tastes delicious and is so smooth!

I bought this powder as a break from my regular protein powder from Protein World and I wish I never had. The texture is vile and doesn’t mix at all so when I attempt to drink it my mouth is filled with thick, sticky lumps of powder. The taste is also nothing like chocolate and is instead more like licking dust. The only way I have been able to use this powder is by downing it all in one and the only reason I continue to use it is because of how expensive it was. DON’T BUY IT. It’s not worth the money and is by far the worst protein powder I have ever tried.

And finally

Bought this a few weeks ago and have been using it in shakes and adding it into cooking/baking. It tastes amazing in protein pancakes and definitely curbs my chocolate cravings

PhD diet whey had an average rating of 3.0/5 on Trustpilot and 4.4/5 on amazon.

There is no such thing as a miracle fat burner, so you should not sacrifice a good, clean diet even if you are taking this. I’d recommend using it as a meal replacement. Perhaps mid-afternoon to stop you from snacking on biscuits or in the evening if that’s the time when you are most likely to pig-out on rubbish food.

Its efficacy is not conclusive but there’s definitely some positive results going by the customer ratings it has on various platforms. In addition, it contains some essential ingredients to help you, these little things do count and go a long way in making your body goals a reality.
