Final answer:
Liposuction is the procedure used to surgically remove localized fat deposits from the abdomen and hips, and is considered a cosmetic surgery distinct from treatments for obesity like bariatric surgery.
Step-by-step explanation:
The procedure used to decrease the size of local fat deposits on the abdomen and hips is known as liposuction. This cosmetic surgery involves the removal of fat from different parts of the body, specifically targeting areas where fat distribution is concentrated and is resistant to diet and exercise. It removes subcutaneous fat located beneath the skin and above the muscles, particularly visceral fat, which is linked to various health risks.
While skin-fold measurements, cognitive behavioral therapy, and lipogenolysis (a type of lipid breakdown) are associated with assessing and managing obesity, these are not procedures for reducing localized fat deposits. On the other hand, bariatric surgery is a treatment for obesity that alters the gastrointestinal system to restrict food intake and absorption but is different from liposuction, which is a purely cosmetic procedure.
