Physical Activity for a Healthy Weight
Regular
physical activity is important for good health, and it's
especially important if you're trying to lose weight or to
maintain a healthy weight.
- When losing weight, more physical activity increases the number of calories your body uses for energy or "burns off." The burning of calories through physical activity, combined with reducing the number of calories you eat, creates a "calorie deficit" that results in weight loss.
- Most weight loss occurs because of decreased caloric intake. However, evidence shows the only way to maintain weight loss is to be engaged in regular physical activity.
- Most importantly, physical activity reduces risks of cardiovascular disease and diabetes beyond that produced by weight reduction alone.
Physical activity also helps to–
- Maintain weight.
- Reduce high blood pressure.
- Reduce risk for type 2 diabetes, heart attack, stroke, and several forms of cancer.
- Reduce arthritis pain and associated disability.
- Reduce risk for osteoporosis and falls.
- Reduce symptoms of depression and anxiety.

How much physical activity do I need?
It really depends on what your health goals are. Here are some guidelines to follow:
Goal | Physical Activity Level for Adults |
---|---|
Reduce the risk of chronic disease | At least 30 minutes of a moderate intensity physical activity, above usual activity, most days of the week. |
Manage body weight and prevent gradual unhealthy body weight gain | Approximately 60 minutes of moderate intensity physical activity most days of the week while not exceeding calorie needs. |
Maintain weight loss | At least 60 to 90 minutes of moderate intensity physical activity most days of the week while not exceeding calorie needs. Some people may need to talk to their healthcare provider before participating in this level of physical activity. See Getting Started with Physical Activity for a Healthy Weight for more. |
For most people, greater health benefits can be obtained by engaging
in physical activity of more vigorous intensity or longer duration.
What do moderate- and vigorous-intensity mean?
Moderate: While performing the physical activity, if your breathing and heart rate is noticeably faster but you can still carry on a conversation — it's probably moderately intense. Examples include—
- Walking briskly (a 15-minute mile).
- Light yard work (raking/bagging leaves or using a lawn mower).
- Light snow shoveling.
- Actively playing with children.
- Biking at a casual pace.
Vigorous: Your heart rate is increased substantially and you are breathing too hard and fast to have a conversation, it's probably vigorously intense. Examples include—
- Jogging/running.
- Swimming laps.
- Rollerblading/inline skating at a brisk pace.
- Cross-country skiing.
- Most competitive sports (football, basketball, or soccer).
- Jumping rope.
