A low-carbohydrate diet, which consisted of limited
carbohydrate intake (20 g/d for 3 months) in the form of low–
glycemic index vegetables with unrestricted consumption of fat and
protein. After 3 months, participants in the low-carbohydrate diet
group increased their carbohydrate intake (5 g/d per wk) until a
stable and desired weight was achieved. A low-fat diet consisted of
limited energy intake (1200 to 1800 kcal/d; 30% calories from
fat). Both diets were combined with comprehensive behavioral
treatment.
