New results from a large, long, head-to-head comparison, published in the July 17, 2008, New England Journal of Medicine, shows that a low-carbohydrate approach or a Mediterranean-type eating pattern are just as good as a low-fat diet for losing weight . They may also be better for preventing or controlling heart disease and diabetes.
- Low fat diet: Focus on low-fat grains, vegetables, fruits, and beans; limit additional fats, sweets, high-fat snacks. Targets: 1500 calories a day for women, 1800 for men; under 30% of daily calories from fat, under 10% from saturated fat.
- Low carb diet: Focus on vegetarian sources of protein and fat; avoid trans fats; no set limit on calories. Targets: Under 20 grams of carbohydrates daily for the first two weeks, under 120 grams a day thereafter.
- Mediterranean diet: Focus on fruits, vegetables, whole grains; poultry and fish instead of red meat; added olive oil and nuts to increase intake of unsaturated fats. Targets: 1500 calories a day for women, 1800 for men; under 35% of daily calories from fat.
