Query: Save your money and buy Dr. Schwarzbein's Principle

Suzanne's premise is a good one, however, the food combining is too difficult so people are unlikely to stick to this regimen in the long run. I read Dr. Schwarzbein's Principle after Get Skinny, and it is very well written and easier to follow. I only want to lose about 8-10 lbs and have lost 6 lbs in the last 4 weeks on the Principle Plan. Plus, I am not denying myself pasta with meat sauce and cheese, bread and butter, real sandwiches etc. Get Skinny is basically Dr. Schwarzbein's eating plan with a new (and questionable) food combining theory.
