Genetic information may soon be used in weight-loss treatments according to a team of researchers, to offer programs tailor-made to individuals in an effort to combat rising rates of obesity. Weight loss itself is often not the biggest challenge for individuals who are overweight, with keeping the weight off often proving to be more difficult. To try and understand why, various groups came together including the National Cancer Institute, National Health Lung and Blood Institute, National Institute of Diabetes and Digestive and Kidney Diseases and Office of Behavioral and Social Sciences Research to form The Working Group, a team of researchers who have been studying how genetics can affect losing and regaining weight.
