Recent research into leptin has revealed what is likely to be very important in the control of appetite, weight loss and the regulation of body weight. Advances in leptin research and its role in the control of obesity would lead to reductions in diabetes, coronary heart disease and many forms of cancer, all of which are increased in obesity.
American adults are overweight and more than 30 percent are obese. Currently 50 million Americans suffer from metabolic syndrome - a disease associated with obesity and encompassing coronary artery disease and type 2 diabetes.
