|As the years go by, the pounds become more difficult to keep off. But have you ever wondered exactly why we experience weight gain as we age?|
There are a variety of reasons, explains Dr. Caroline Apovian, vice-president of The Obesity Society. A change in hormones, a more sedentary lifestyle, and an increase in stress and decrease in sleep due to added responsibilities are just a few.
A major reason for middle aged weight gain is the natural muscle loss we all experience (sarcopenia)," says Dr. Apovian.
"The amount of lean muscle mass we have is the primary determinant of metabolic rate. In other words, the more muscle mass we have, the more calories we will burn.
Unless something is done to actively protect and build up that lean muscle mass, our bodies will require fewer calories, our metabolisms will slow, and the lost muscle will be replaced by fat."
So, what can you do to prevent sarcopenia? Dr. Apovian offers three tips:
*Exercise with weights at least twice per week, building up in both weight and intensity as you progress," she says.
*Eat a diet rich in lean protein sources, including protein smoothies."
*Get plenty of sleep," Dr. Apovian concludes. "Amongst other health benefits, this gives the body time to repair and rebuild the muscles."
