In the context of physical health, weight loss is the process of losing body weight, usually by losing fat. To achieve healthy weight loss, most experts recommend a combination of healthy eating patterns and regular physical exercise. Some people try to lose weight by using drugs such as fenfluoramine, nicotine or cocaine (see Anti-obesity drugs), herbs such as ephedra, or surgery such as liposuction.
A loss of weight can also be the symptom of some mental or physical diseases or disorders, such as anorexia nervosa or the cachexia associated with cancer or AIDS.
