Comparison of Diets for Weight Loss and Heart Disease Risk Reduction

JAMA. 2005;293(13):1589-1591. doi:10.1001/jama.293.13.1589

To the Editor: The study by Dr Dansinger and colleagues1 suggests that all 4 diets (Atkins, Ornish, Weight Watchers, and Zone) are comparable because the changes in risk factors for coronary heart disease (CHD) are similar. I believe that this would not be a proper conclusion because the study did not distinguish between cardiovascular risk factors and direct measures of cardiovascular disease.
