Nutrient and food intake in obese women on a low-fat or low-calorie diet

One hundred twenty-two healthy, nonsmoking women 20% to 40% above ideal weight were randomly assigned to a low-fat or low-calorie diet intervention. At 12 months, 39 remained in the low-fat group and 36 in the low-calorie group. The low-fat group reported a significantly greater decrease in intake of calories from fat and increase in calories from carbohydrates compared with the low calorie group. Weight loss, calorie intake, physical activity, and rating on palatability, satiety, and quality of life were not significantly different for the two groups.
