beats-low.html

Study in USA of 2 dozen people shows that even on unrestricted intake
GI can potentially beat a traditional low fat low calorie diet.

Low-fat dieters cut their daily intake by 250 to 500 calories, limited
fat to less than 30 percent of their total calories, and got between 55
and 60 percent of calories from carbohydrates.
Ludwig noted that even though low-glycemic index dieters had no calorie
limits, they likely didn't overeat because they felt less hunger after
eating foods that take longer to digest.
