How can you lose weight? With diet and exercise. The key to success is developing healthy diet and exercise habits. You may be thinking that you don't 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 30 to 60 minutes of moderately intense physical activity most days of the week.
