Diet and exerciseBy Mayo Clinic staff
How can you lose weight? With diet and exercise. The key to successful weight loss is developing healthy diet and exercise habits. You may not like those words — diet and exercise. Don't get hung up on the words. Diet just means eating healthy, lower calorie meals. Exercise means being more active.
Although people often focus on diet when they're trying to lose weight, being active also is an essential component of a weight-loss program. When you're active, your body uses energy (calories) to work, helping to burn the calories you take in with food you eat.
Cleaning the house, making the bed, shopping, mowing and gardening are all forms of physical activity. Exercise, on the other hand, is a structured and repetitive form of physical activity that you do on a regular basis.
Whatever activity you choose, do it regularly. Aim for at least 150 minutes a week of moderate physical activity or 75 minutes a week of vigorous aerobic activity — preferably spread throughout the week. Keep in mind that you may need more physical activity to lose weight.
