A low-carb diet and a Mediterranean-style diet both helped people lose more weight than a traditional low-fat diet in one of the longest and largest studies to compare the various weight-loss techniques.
The low-carb diet also improved cholesterol more than the other two, even though some critics had predicted the opposite result.
All three approaches achieved weight loss and improved cholesterol.
The low-fat diet restricted calories and cholesterol and focused on low-fat grains, vegetables and fruits as options. The Mediterranean diet had similar calorie, fat and cholesterol restrictions, emphasizing poultry, fish, olive oil and nuts. The low-carb diet set limits for carbohydrates, but none for calories or fat, although it urged dieters to choose vegetarian sources of fat and protein.
