The advantage of fake foods is that they regulate your calorie and protein intake, to maximize weight loss. The pre-digested liquid protein I use in the office contains 60 calories and 15 grams of protein per serving. The strawberry banana smoothie I use contains 100 calories and 20 grams of protein. The diet wafers I use contain 200 calories and 15 grams of protein. The diet cookies I use contain 150 calories and 15 grams of protein. The diet bars I use contain 150 calories and 15 grams of protein. Most patients eat 500-600 calories of almost pure protein a day, and lose 5-10 pounds a week.
