Eating a Mediterranean diet high in vegetable fats such as olive oil or nuts with no calorie restrictions had little effect on body weight or waist circumference compared with a low-fat diet, which increased central adiposity, according to recent findings (Estruch R et al. Lancet Diabetes Endocrinol. doi:10.1016/S2213-8587(16)30085-7 [published online June 6, 2016]). This study was a secondary outcomes analysis of the previously published randomized PREDIMED trial, which studied 3 diets for the prevention of cardiovascular disease (Estruch R et al. N Engl J Med. 2013;368:1279-1290).
