Who is Diet Whey designed for?
Diet Whey is designed for individuals looking to maintain muscle mass whilst in a diet phase of their training.
Whilst calories are low, it is important to ensure protein remains high and in consistent doses for optimal muscle maintenance. Protein not only requires more energy to break it down, it also keeps you satiated for longer, making it an important macro nutrient when in a diet phase.
The Diet Whey reformulation includes active ingredients to support fat loss including CLA, L-Carnitine, green tea extract and flaxseed.
We have kept the best-selling formula the same but have refined the details such as taste, texture and ensured the highest quality protein is being used. Therefore, creating an even better tasting Diet Whey, that is easy to mix and smooth to drink.
Informed Protein Certification
Informed Protein Certification verifies the accuracy of the protein count on the label. Driven by innovation and excellence, INFORMED is the leading independent supplement testing provider, specializing in protein verification, doping control, and supplement analysis. At PhD it’s important to us to provide the highest quality supplements to ensure our customers get the best to support their goals.

Maintain lean muscle with Diet Whey
Protein is the building blocks of life as it provides the amino acids that help the body grow and repair. Our hair, skin, muscle, and all our body tissues are all made from the protein we eat. To maintain muscle mass, a high protein diet is essential, especially in a calorie deficit. Diet whey provides 20g of informed protein with a low sugar and fat blend to support a low-calorie diet whilst maintaining muscle mass.

I was worried when I saw that it was "new and improved", as this often means the opposite. I need not have been concerned though, it is still my favourite protein powder! Easy to mix and even easier to drink, or mix into my porridge.

Great tasting whey protein powder that I have in my porridge every morning. Easy to mix although the new formula does seem to be more liable to clumping up. Nothing horrible, just there was none before.

The new recipe is so so bad, I've been buying PHD diet whey for years & used to love it but the new recipe taste is so artificial & leaves an artificial sweetener taste in your mouth for hours afterwards. It's such a shame as it's now inedible so I've had to cancel my subscription
