A cardiologist's revolutionary weight-loss plan that allows dieters to enjoy good carbs while still losing weight The glycemic index has been the basis of many popular diets. But it doesn't take into account the serving sizes people actually eat and eliminates too many foods for dieters to stick with it. Now Dr. Robert Thompson's breakthrough program uses the glycemic load — the glycemic index adjusted for serving size — to take the GI a step forward. The glycemic load is a more accurate and effective tool in controlling weight and insulin resistance, allowing dieters to eat more foods while still burning fat, cutting cravings, and speeding up their metabolism. Safe, simple, and scientifically proven, it's the smartest weight-loss plan yet.
