My best diet is Basically organic veggies, veggie juice and organic meats. No processed food at all. No fruit juice, no artificial sweetners. No sugar, caffene, wheat, processed grains (whole grains are fine). Only occassional fresh fruit, don't let it become a sugar substitute.
The Mediterranean diet also ranked first on the US News and World Report list for easiest diet to follow, best plant-based diet and best diet for diabetes. It came in second for best heart-healthy diet, just behind DASH.
