The Mediterranean diet was associated with a mean weight loss of 4 pounds at six months in adults with type 2 diabetes, while other diet plans studied did not yield similar results, according to an analysis of 20 studies comparing seven popular diets in diabetes patients. Researchers also noted a 4% to 10% increase in good cholesterol and a reduction of as much as 9% in triglycerides in patients who were on the Mediterranean, low-carb or low-glycemic diet. The results appear in The American Journal of Clinical Nutrition.
