For patients who are overweight or moderately obese (BMI 25 to 32), I recommend a caloric deficit of500 to 750 kilo-calories per day to achieve 1 to 1.5 pounds of weight loss per week. The dietitian can design a low calorie, food-based diet that is either balanced-deficit (reducing total number of calories while keeping proportions from carbohydrate, fat, and protein roughly the same as before), or fat-deficit, with most of the caloric reduction resulting from restriction of fat intake. The latter approach is preferable in light of the typical American diet that is too high in fat, especially saturated fat. Also, a greater volume of food can be eaten on a diet that emphasizes complex and vegetable-source carbohydrates and reduces fat to < 30% of calories consumed.

WHAT IT IS A three-phase plan that has been likened to the low-carbohydrate Atkins program because during the first two weeks, South Beach eliminates most carbs, including bread, pasta, potatoes, fruit and most dairy products. In PHASE 2, healthy carbs, including most fruits, whole grains and dairy products are gradually reintroduced, but processed carbs such as bagels, cookies, cornflakes, regular pasta and rice cakes remain on the list of foods to avoid or eat rarely.
