Therapeutic weight loss techniques
The least intrusive weight loss methods, and those most often recommended by physicians, are adjustments to eating patterns and increased physical exercise. Physicians will usually recommend that their overweight patients combine a reduction of the caloric content of the diet with an increase in physical activity.
Other methods of losing weight include use of drugs and supplements that decrease appetite, block fat absorption, or reduce stomach volume. Finally, surgery may be used in more severe cases. Bariatric surgery artificially reduces the size of the stomach, limiting the intake of food energy.
