Eat before or after exercise?

DEAR DR. GOTT: I walk about two miles every morning to keep in shape. I’ve developed a paunch and what my wife calls a bicycle tire around my middle. To get rid of the paunch and tire, is it better to do the morning walk on an empty stomach or to walk after I’ve eaten something?

Twenty years ago, I would run three or four miles every morning right after I got up, consuming nothing but water, and it seemed to work fine.

DEAR READER: The key words here are “twenty years ago.” Unfortunately, our metabolism changes as we age, and what worked then for most of us probably won’t work as easily now.

You should match your energy intake to your energy needs. If you awaken in the morning and plan a rigorous schedule of exercise, you should eat prior. I’m not speaking of loading up on pancakes and bacon before jogging, but I am recommending a lighter meal to give you the energy to partake in the physical activity. Keep in mind that your body customarily burns about 100 calories an hour at rest and while you are sleeping. So, if you sleep eight hours at night, you have already expended 800 calories on awakening. To avoid major fluctuations throughout the day, you might consider what I call grazing — eating small to moderate meals every three to four hours. In that way, you should match your energy intake and output.
