Weight Loss 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.
Weight Loss Surgery There are a number of different gastric bypass surgeries which are referred to as weight loss surgeries. One is the duodenal switch (DS) and the other, more popular one is the Roux-en-Y (RNY) surgery. See Roux-en-Y gastric bypass surgery .
