Regular exercise of at least four hours per week is linked to weight maintenance. People who exercise regularly, and eat reasonably healthy, often lose weight not because of how many calories they burn in a workout. They do it because of how much their appetite is affected by their activity level, and how regular they are. Consistency helps you build momentum to meet your goals. Your appetite hormones are directly affected by exercise type and intensity. Ghrelin, your ‘hunger hormone’, is suppressed right after you do something physically strenuous, and leptin, your ‘satiety hormone’ is increased. How long that appetite suppression lasts depends on the intensity and duration of your workout. The greater the intensity, the greater the appetite suppression!
