Increased protein intake is essential for bodybuilders and older adults. Both need to maximize muscle protein synthesis while increasing fat burning. When cutting for contests, bodybuilders must become as lean as possible while sparing muscle mass. Obesity is a significant problem in older adults. However, when they lose significant weight through dieting, they typically lose muscle mass that they can't gain back. Protein quality is an important consideration in both groups. A study led by Christopher Mobley and colleagues from Auburn University in Auburn, Alabama found that whey protein promoted muscle protein synthesis better than egg protein or a combination of whey and egg proteins. Whey protein was also more effective for fat mobilization. (Journal of the International Society of Sports Nutrition 12:14, 2015)
