Exercise is perhaps the most important part of managing weight. It is virtually impossible to lose weight healthily without engaging in a certain amount of physical exercise. Exercise is a great motivator when following a weight-loss regimen and many individuals also find it easier to make healthy eating choices when they are following a daily exercise routine.

In order to lose one pound of body fat per week, individuals must create a deficit – either through diet restrictions or exercise – of 500 calories per day (3,500 calories per week). The United States Surgeon General recommends moderate physical activity for 30 minutes on most days of the week. However, this may not be sufficient to achieve weight loss or weight maintenance for some individuals. The Institute of Medicine (IOM) of the National Academy of Science (NAS) recommends 60 minutes of moderate physical activity on most days to prevent weight gain and to achieve the health-related benefits of regular activity. It is important to consult a physician to help determine an appropriate exercise regimen that is appropriate and safe.
