Good Carb Diet Overview + 350 Great Recipes
This program is based largely on reducing or eliminating foods with a high
glycemic index — a measure of the rise in blood sugar after eating a particular food. The South
Beach Diet, Agatston writes, “corrects the way your body reacts to the very foods that made you
overweight,” especially sugar.
Reality Check: “The glycemic index is interesting,” notes Wadden, but there isn’t enough
evidence to prove its effectiveness in weight loss. Adds Wing, “For weight loss, the bottom line
continues to be calories, not the glycemic index.”
WHAT IT PROMISES Eight- to 13- pound loss in the first two weeks; about one to two
pounds per week after that. Belly fat is said to vanish first, though Agatston doesn’t explain why.
