Putting on weight? Blame it on your genes. An international team, led by Garvan Institute, Australia has carried out the study and found that the relationship between overeating and weight gain is actually linked to a person's genetic history. <br/><br/>In their study, the scientists have shown that healthy people with a genetic predisposition to Type 2 diabetes gain more weight by overeating over the short term than their non-genetically prone counterparts.<br/><br/>Seventeen people with a family history of Type 2 diabetes, along with 24 people without any family history, took part in the research.<br/><br/>The groups were matched for age, weight and lifestyle. Team leader Prof Lesley Campbell said that the study shows just how quickly the body reacts to overeating, and how harmful it can be in susceptible people. <br/><br/>According to the scientists, an early warning sign of diabetes is the development of insulin resistance, usually triggered by excess body fat.<br/><br/>
