Impact of Genetics on Obesity

The human body contains an appetite-control system that makes losing weight and keeping the weight off difficult. Appetite is controlled by a hormone called leptin, which is secreted by body fat. Leptin is carried by the blood to the brain, where it reduces appetite. With weight loss, less body fat means less leptin reaches the brain. This reduction in leptin causes a drive to eat. The drop in leptin also causes the brain to derive more pleasure from food, especially fatty and sweet foods. This cycle of feedback makes maintaining weight loss difficult for most people. It also means that eating is not always entirely conscious, voluntary behavior.

Science has gathered data that suggests that genetics plays a strong role in obesity. Recent research indicates that about 80 percent of variations in body weight are determined by genes. This means that body weight is determined by genes to about the same degree as height. Such a strong genetic component means that obesity and weight-loss are not fully under an individual’s control, as previously thought.

While genes play a factor in weight gain, weight loss is still possible, especially through the help of Midwest weight control.
