Treating those who are overweight and obese is primarily about restoring energy balance. Losing excess weight requires an energy deficit; in other words, using more calories than you eat. For people who are obese, it’s generally recommended to set an initial short-term goal of losing five to 10 percent of their total weight over six months. This usually means losing half a pound to two pounds a week for six months. An energy deficit of 500 to 1000 calories a day is needed to achieve this kind of weight loss.

Achieving energy deficit and weight loss requires comprehensive lifestyle change, and there are three pillars that support this change: diet, physical activity, and behavior. Even after the extra weight comes off, maintaining energy balance is crucial to keeping weight under control. This means that treating obesity can be a lifelong commitment.
For some people, lifestyle changes may not lead to enough weight loss to improve health. In these cases, healthcare providers may recommend additional treatment, including weight-loss drugs or surgery.
