The current dietary recommendations aim at reducing the total fat in the diet to less than 30% of calories, increasing carbohydrates to 55-60%, and protein from lean meat and dairy products to 15-20%, and to keep the intake of sugar sweetened soft-drinks limited. There is good evidence from meta-analyses of intervention studies that a low fat diet can prevent weight gain in normal weight individuals, induce a small but clinically relevant weight loss in overweight individuals, and also reduce the risk of cardiovascular disease and type 2 diabetes.
