Most of us blame age for our growing waistlines. We assume that it is just part of life that as we grow older, we grow plumper. The truth is that it is a vicious cycle of slowing metabolism, decreased activity, and decreased muscle mass that contributes to weight gain in those who are 35 years of age or older.
As we age, we burn fewer calories per pound of body weight than we did when we were younger. Our lean body mass is also less than when we were younger.
