Scientists have discovered a gene that ups the risk of obesity, a breakthrough which they claim offers insight into why some people put on weight while others with similar lifestyles stay slim. A British-led team has found that people who inherit two copies of the variant, which lies close to a gene called MC4R, weigh an average of 1.5 kg more than those without the genetic variation, the Nature Genetics journal reported.
The results confirm the existence of some of the newly identified genes.
