my GF had success with it but it seems kind of strict for me and im trying to understand the science behind it:
quick summary from wiki:
the first 2 weeks seem tough... what is so magical about eliminating these substances? my social group drinks, and my schedule involves a lot of eating out in the city where avoiding carbs completely isn't somewhat feasible. So if i drink on the weekend or have a sandwich the diet is completely fv(k and i have to start again??? cant i just prolong it or something? what is the biochemistry behind itAgatston divides the South Beach Diet into three phases, each progressively becoming more liberal. "Phase 1" lasts for the first two weeks of the diet. It eliminates all sugars, processed carbohydrates, fruits, and some higher-glycemic vegetables as well. Its purpose is to eliminate the hunger cycle and is expected to result in significant weight loss.
"Phase 2" continues as long as the dieter wishes to lose weight. It re-introduces most fruits and vegetables and some whole grains as well.
"Phase 3" is the maintenance phase and lasts for life. There is no specific list of permitted and prohibited foods. Instead, the dieter is expected to understand the basic principles of the diet and live by the principles.
