In the context of physical health, weight loss is the process of losing body weight, typically by losing fat. To achieve weight loss, more caloriesmust be expended than taken in. This can be achieved by reducing the amount of food consumed, increasing physical activity or a combination of the two. For healthy weight loss, most experts recommend a combination of healthy eating patterns and regular physical exercise. Other methods of losing weight include use of prescribed or herbal drugsor chemicals that decrease appetiteand/or increase physical activity, such as fenfluoramine, ephedra, nicotineor cocaine(see anti-obesity drugs). Surgicaloptions are also available. Liposuctionremoves targeted area of fat and tissue while bariatricsurgeries can result in large weight loss by reducing the size of the stomach or reducing the absorption of food energy. Surgical and drug options may have serious side-effects.

A loss of weight can also be the symptomof some mental or physical diseases or disorders, such as anorexia nervosa, cachexiaassociated with cancer, AIDSor diabetes.

Weight loss can help to relieve symptoms of a variety of conditions, such as diabetes, back pain and disorders of the spine, pain in the kneeor legs, and many heartconditions. For healthy weight loss, a physician should be consulted to develop a weight loss plan that is tailored to the individual.
