Normal or high protein for weight management?

A study published in the May issue The Journal of Nutrition aimed to gather a consensus of the different outcomes of energy-restricted high-protein diets depending on the dietary protein content. The objective was to determine the effects of dietary protein content on body weight loss-related variables during a 6-month energy restriction with the use of diets containing protein. In overweight and obese participants, protein intake was consistent in the normal protein diet and high protein diet groups throughout the study. Body fat mass similarly decreased in the normal protein diet and high protein diet groups. Fat free mass, resting energy expenditure, and diastolic blood pressure changed favorably with the high protein diet compared with the normal protein group after body weight loss.
