Ph D Nutrition Diet Whey contains a precision, slow-release protein blend to maximise satiety & ensure no hunger pangs or energy crashes during the day. Diet Whey is a high-protein meal with a huge difference; it contains a multitude of potential fat-loss ingredients which may assist with the building of fat-free muscle, without any bulking or excess calorie intake. Containing Whey Protein Concentrate, Milk Protein Concentrate & Soya Protein Isolate, Ph D Diet Whey provides the fast-acting protein sources to assist lean muscle building, but also the slow-release protein sources to help keep hunger at bay during your busy working day.A drink that claims to aid with the reduction of body fat & enhancement of muscle tone should not contain added simple sugars, it’s a contradiction in terms. There are a variety of high-protein diet powders on the market that contain good protein sources, but then spoil it by using dextrose or maltodextrin as the carbohydrate source.
