Food=physical activity

"The key to weight control is keeping energy intake (food) and energy output (physical activity) in balance. When you consume only as many calories as your body needs, your weight will usually remain constant. If you take in more calories than your body needs, you will put on excess fat. If you expend more energy than you take in you will burn excess fat."

Huzzah for keeping an even keel...now if I can figure out how to burn more then I intake I might lose weight :)
