I recently read in "First" magazine of drinking Soy and Whey for breakfast and lunch with a 300 calorie or less dinner. The weight loss that they reported was remarkable and it seems very doable. They said that you have to consume greater than 20g of protein in your soy or whey shake. Does anyone have any first hand knowledge of this plan or the long term affects of protein?

This is a condensed version of the plan that was in the magazine.


Breakfast and lunch

1 soy or whey shake blended with 1/2 cup frozen fruit.
or
1 soy or whey bar with a side of fruit.

Dinner

4oz lean meat with 2 cups steamed vegetables
or
Any Stouffer's Lean Cuisine, Healthy Choice, or Weight Watchers Smart Ones prepared dinner containing 20 grams or protein and 300 calories or less.
