Being born into a fat family is no excuse for obesity and exercise is the way to stay in shape, a new study says.
Experts said people who are genetically predisposed to obesity, but take regular exercise, cut the risk of being fat by 40 per cent, reports express.co.uk.
As there are cases where some people struggle to lose weight even when they go on the most extreme diets, and end up blaming their genes for no-weight loss, a study has confirmed that exercise is the key to staying slim, even for those with the wrong genes.
Ruth Loos, lead author of the study said: "Our research proves that even those who have the highest risk of obesity from their genes can improve their health by taking some form of daily physical activity."
"People don`t have to run marathons to make a difference either - walking the dog or working in the garden all counts. It goes to show we`re not complete slaves to our genetic make-up and really can make a big difference to our future health by changing our behaviour," he added.
