Substantial evidence exists supporting the consumption of increased dietary protein as a successful strategy to prevent and/or treat obesity through improvements in weight management. Higher protein diets lead to greater reductions in body weight and fat mass concomitant with the retention of lean mass compared to standard protein diets. Furthermore, higher protein diets also prevent weight re-gain following weight loss.

The effectiveness of these diets may be due, in part, to the modulations in the signals that control appetite, satiety, and food cravings. Specifically, the consumption of higher protein meals leads to reductions in hunger, increases in fullness (satiety), and reductions in the neural activation in brain regions controlling food reward/cravings. These responses are particularly robust at the breakfast meal and lead to reductions in unhealthy evening snacking.

Collectively, these data support the beneficial effects of increased dietary protein to modulate appetite control, satiety, and weight management.
