Scientists at the University of Naples studied 192 overweight and obese men, putting half the men on a Med Diet (if overweight) or a Med Diet plus exercise and calorie restriction (if obese), while the other half followed a conventional diet. After two years, the Med Diet group had lost, on average 14 kg (31 lbs), while the control group had lost just 2 kg. Moreover, the Med Diet group showed “significant amelioration of multiple risk factors” including improved cardiovascular markers, reduced oxidative stress, and improved insulin sensitivity.
