My Dr. does suggest a protein shake to help me get the protein I need. It doesn't seem like I can get enough through food. So I found a protein powder that is low calorie, low carb, low sugar, and low fat. It has 23 grams of protein and tastes great. It does not clump and it is not gritty. I really like it and I can drink it in skim milk. I also can make smoothies with it. I add all kinds of fruits and vegies. It has made me feel better and has helped with my energy level. I have been using it for a while now. It is at www.fitbodi.net it is called slim.
