To the Editor: The study by Dr Ludwig and colleagues1 provides evidence that a high intake of low-fiber foods is a key mediator of the epidemic of obesity in the United States. The authors plausibly suggest that this effect is primarily attributable to the often high glycemic index of such foods. A secondary but no less intriguing finding of their study is that increased protein intake is linked to weight gain. The 2 findings may share a common mechanism.
