Reading edition

(Yes, this is the same concentrated protein drink doctors have recommended for years ... as a pleasant way to get more protein in the daily diet of persons whose daily intake of this vital nutrient may be inadequate.) In the reducing diet, the Knox Drink works 3 ways:

2. It curbs your appetite, so you are satisfied with less food
3. It supplies you with additional protein, a must when you are taking off excess weight.
