Being active is an important part of any weight-loss or weight-maintenance
program. When you're active, your body uses more energy (calories). And when
you burn more calories than you consume, you lose weight.
Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you
need to burn 3,500 calories more than you take in to lose 1 pound. So if you
cut 500 calories from your diet each day, you'd lose about 1 pound a week (500
calories x 7 days = 3,500 calories). Because of changes that occur in the body
over time, however, calories may need to be decreased further to continue
weight loss.
While diet has a stronger effect on weight loss than physical activity
does, physical activity, including exercise, has a stronger effect in
preventing weight gain and maintaining weight loss.
For most healthy adults, the Department of Health and Human Services
recommends these exercise guidelines:
·
Aerobic activity. Get at least 150 minutes a week of
moderate aerobic activity or 75 minutes a week of vigorous aerobic activity.
However, to effectively lose or maintain weight, some people may need up to 300
minutes a week of moderate physical activity. You also can do a combination of
moderate and vigorous activity. The guidelines suggest that you spread out this
exercise during the course of a week, and sessions of activity should be at
least 10 minutes in duration.
·
Strength training. Do strength training exercises at
least twice a week. No specific amount of time for each strength training
session is included in the guidelines.
Moderate aerobic exercise includes such activities as brisk walking,
swimming and mowing the lawn. Vigorous aerobic exercise includes such
activities as running and aerobic dancing. Strength training can include use of
weight machines, or activities such as rock climbing or heavy gardening.
As a general goal, aim for at least 30 minutes of physical activity every
day. This chart shows the estimated number of calories burned while doing
various exercises for one hour. Specific calorie expenditures vary widely
depending on the exercise, intensity level and your individual situation.
