Macronutrient profiles of popular diets, the OmniHeart and Dietary Approaches to Stop Hypertension (DASH) study diets, the American Heart Association Therapeutic Lifestyle (AHA TLC) guidelines (5), and typical US macronutrient intakes as reported in the third Health and Nutrition Examination Survey (NHANES III; 24). The eating patterns are ordered with the highest-carbohydrate diet starting on the left and the lowest on the right. The Atkins diet profile is for the life-long maintenance phase, and the South Beach diet profile is for phase 3. Small amounts of alcohol (0.2−0.8% of energy) were also present in the Ornish, Mediterranean, Atkins, Zone, and South Beach diets. Percentages may not add up to 100% because of rounding.
