If you exercise until you are exhausted, you lose your appetite for a while. You should exercise longer, not harder because too hard can cause muscle damage and possible loss of lean tissue.
Exercising and losing weight are the two most important things to do if you are insulin-resistant.
Your body burns calories more efficiently the first twelve hours of the day.
As long as you exercise, being a little bit heavy may not in itself jeopardize your health.
You may burn as many as 80 calories an hour while you sleep, depending on your weight. The heavier a person is, the more calories they burn an hour.
