Research published by the American Dietetic Association studied the health effects of three diet programs: Atkins, South Beach, and Ornish. All three produced weight loss, but the subjects on the Atkins diet, which cuts out carbohydrates and recommends foods high in saturated fat like red meats and butter, showed a marked increase in LDL (bad) cholesterol. The diet best at achieving significant reductions of LDL cholesterol was the Ornish diet, a low-fat plan full of healthy fiber-rich carbs like fruits, vegetables, whole grains, and beans, similar to the Pritikin Eating Plan. On this diet, the subjects lost weight and also, after one month, netted an average 17% reduction in cholesterol levels as well as improved blood vessel function.
