Jen, KLC (1988) Effects of a diet composition on food intake and carcass conposition in rats Physiology and Behavior, 42:551-556.

Rats (n=48) were fed a high fat diet for 16 weeks to induce obesity, then were fed a control diet to normalize weight. Then the rats were fed a high protein, high fat, or a chow diet. The high protein diet resulted in maintenance of normal body weight by reducing feed efficiency , the chow diet resulted in higher body fat, compared to controls, and the high fat diet stimulated weight gain. Therefore, a high protein diet has a higher probability of enhancing weight loss maintenance in a weight-reduced obese than a usual well-balanced diet
