The expert claim that having a flawed copy of the FTO gene - which was discovered in 2007 - could make you eat more and put on more weight than those who have a normal FTO gene. And that, they say, could include around 14 heavier. Male mice with the flawed gene ended up 10% heavier.
Published in the journal Nature Genetics, the study suggests some people may well have a genetic predisposition to gaining weight, And if the researchers can get to the bottom of how the flawed gene works, they could develop drugs to treat it.
That there may be a genetic reason for why some people put on weight while others don't has divided public opinion in recent years. But thanks to ongoing scientific advances the argument is slowly tipping in favour of obesity being hereditary, if not for all the quite possibly for some. For instance, researchers recently suggested that your body shape is largely down to your genes.
