Research shows that between the ages of 30 and 50, we are likely to lose 10 percent of the total muscle in our body. By the time we are 60 that percentage will double.
To make matters worse, it’s likely that lost muscle is replaced by fat over time, according to a study in the American Journal of Clinical Nutrition. It was found that even people who maintained the same body weight for 38 years lost 3 pounds of muscle and added e pounds of fat per decade. Not only does this make us look flabby, it increases our waist size. This is because 1 pound of fat takes up 18 percent more space on our body than 1 pound of muscle.
