This study took dieters who had lost 5-10% of their body weight and randomized them to a control group (15% protein) or a high-protein group (18% protein). Weight was monitored over a 6-month period. During this 6-month period, the control group gained back 7 pounds and the protein group gained back only 2 pounds of the weight that was previously lost. Not only was weight regain less in the protein group, they also gained only muscle not fat. One reason for the better weight maintenance in the protein group was because of enhanced satiety, that is, the protein group was less hungry. A higher protein diet was effective at maintaining weight loss compared to a normal protein diet.
