If you haven’t heard of body weight set point, it’s an idea proposed by Richard Keesey of the University of Wisconsin in 1997 that suggests everyone has a preprogrammed weight regulated by the body’s metabolism. A study done by Nicole Stob, PhD, from the University of Colorado-Denver, related to whether or not liposuction resulted in permanent weight loss found that weight returns, and that has implications for Keesey’s theory.
According to Stob, the study involved thirty-nine men and women who had extra fat removed from their hips, bellies, or thighs. They were then monitored over the course of a year, and researchers discovered when the weight returned, it did not reappear in the spot where it was taken from but rather it reappeared in the upper body, such as in a person’s upper arms or in the shoulder blades.
Stob’s study is significant because the results may contribute towards finding and isolating the gene or genes that make it so difficult to keep off extra weight. Researchers have already learned from Stob’s study that the genes responsible for the production of collagen, kick into high gear at the site where fat is removed. So, if that’s true, it could mean the body fights against weight loss and instead tries to maintain the body weight set point.
