The tendency of Americans to losing weight is continuing. Scientists from the University of Washington, Seattle, conducted research concerning obese people who lost weight by dieting and those who lost weight after gastric bypass surgery. The aim of the study was to compare their levels of ghrelin, a hormone believed to stimulate appetite.

Scientists from the University of Washington, Seattle, conducted research concerning obese people who lost weight by dieting and those who lost weight after gastric bypass surgery. The aim of the study was to compare their levels of ghrelin, a hormone believed to stimulate appetite.
The hormone is produced in the stomach. The reduced production of ghrelin after the surgery is believed to be responsible for patients success in weight loss.
The ghrelin levels were measured in 13 overweight people who had dieted. Within six months to the levels of five participants after undergone surgery, they discovered that the dieters had a 17% decrease in body weight with a 24% increase in ghrelin blood levels. The bypass patients noticed a 36% reduction in body weight, and their ghrelin levels were 12% lower than the study’s dieters, and 77% lower than control participants of lower weight.
