Keeping a healthy weight is crucial. If you are underweight, overweight, or obese, you may have a higher risk of certain health problems.
Eating too much or not being physically active enough will make you overweight. To maintain your weight, the calories you eat must equal the energy you burn. To lose weight, you must use more calories than you eat. A weight-control strategy might include
Choosing low-fat, low-calorie foods
Eating smaller portions
Drinking water instead of sugary drinks
Being physically active
Eating extra calories within a well-balanced diet can help to add weight.
