I did the HCG diet and i just want to tell you guys that it is the best diet i have ever tried. I know why the FDA has been trying to prevent Kevin from telling people about this diet. There will be no reason for anyone to get gastric bypass or use diet pills after trying this diet. It was kind of hard keeping to the low calorie diet but i never lost 20 pounds in one month like i did with hcg diet. Before when i dieted i could lose 6-8 pounds if i starved myself for a month. But kevins diet makes you lose a min of 15-20 if you stick to the diet. Men lose 20-30 it seems like. It's amazing. good luck.
