Regular physical activity is important to help you lose weight and build an overall healthy lifestyle. Physical activity increases the number of calories your body uses and promotes the loss of body fat instead of muscle and other nonfat tissue. Research shows that people who include physical activity in their weight-loss programs are more likely to keep their weight off than people who only change their diet. In addition to promoting weight control, physical activity improves your strength and flexibility, lowers your risk of heart disease, helps control blood pressure and diabetes, can promote a sense of well-being, and can decrease stress.



Any type of physical activity you choose to do --vigorous activities such as running or aerobic dancing or moderate intensity activities such as walking or household work -- will increase the number of calories your body uses. The key to successful weight control and improved overall health is making physical activity a part of your daily life.

For the greatest overall health benefits, experts recommend that you do 20 to 30 minutes of vigorous physical activity, such as aerobic dancing, and brisk walking three or more times a week and some type of muscle strengthening activity, such as weight resistance, and stretching at least twice a week. However, if you are unable to do this level of activity, you can improve your health by performing 30 minutes or more of moderate-intensity physical activity, like taking the stairs instead of the elevator or playing actively with your children over the course of a day, at least five times a week.

When including physical activity in your weight-loss program, you should choose a variety of activities that can be done regularly and are enjoyable for you. Also, if you have not been physically active, you should see your doctor before you start, especially if you are older than 40 years of age, very overweight, or have medical problems.
