Nutrition & ingredients
Each 25 g scoop contains 17 g protein, modest carbohydrates (with oats for texture) and under 2 g fat. The mix includes whey protein concentrate, milk protein isolate and soy protein isolate. Added green tea extract, l‑carnitine and CLA are marketed for metabolism support, though research results are mixed. The formula also includes vitamins B6, B12, zinc and magnesium. Sweetened with sucralose and acesulfame K.
Taste & mixability
Flavours like Chocolate Mint and Vanilla Crème are well‑reviewed by customers for their dessert‑like taste. The texture is thicker than standard whey due to oats, which some users find more filling. It mixes smoothly in a shaker with minimal foam.
Use cases
Diet Whey is marketed for calorie‑controlled diets and lean muscle maintenance. Customer reviews suggest it can be filling as a snack or convenient shake between meals. Its lower protein per scoop means some users double the serving, increasing calories accordingly.

FAQs
Is PHD Diet Whey suitable for vegetarians?
Yes. It is suitable for vegetarians but contains milk and soy proteins, so it’s not suitable for vegans.
Can Diet Whey help me lose weight on its own?
No supplement can replace a balanced diet and exercise regimen. Diet Whey can support weight‑loss goals by providing protein and satiety with minimal calories, but it must be combined with a calorie deficit and activity.
How should I use Diet Whey?
Mix one scoop with water, milk or plant milk and consume it as a snack or post‑workout shake. You can also blend it into smoothies, oats or baking recipes. Adjust serving size to your protein needs.
Does Diet Whey contain caffeine?
The green tea extract may contain trace amounts of caffeine, but the total caffeine content per serving is low. If you’re sensitive to caffeine, it’s unlikely to cause jitters.
Is Diet Whey suitable for those with lactose intolerance?
Diet Whey contains milk proteins and may not be suitable for those with severe lactose intolerance. Consider a lactose‑free whey isolate such as Isopure Zero Carb if you need a dairy‑free option.
