According to the Daily Mail, researchers at Maastricht University in Holland have identified a mutated DNA strand that makes some women two and a half times more likely to put on a stone in weight.
Having followed the weight gain and loss of more than 5,000 men and women over the course of ten years, the scientists found the impaired version of the MMP2 gene was common in women, but not in men.
The gene fuels the development of fatty tissue, causing women to gain weight more easily. Dr Freek Bouwman, who worked on the study, reportedly claimed at least 30 per cent of women have the mutated strand of DNA, and hopes that the discovery of the gene may lead to tests that could pick out those women at risk of obesity in the future.
Some men suffer a similar problem with their own 'fat gene', FTO, which is thought to cause them to crave junk food.

Would it help you or hinder you to know that you carry the 'fat gene'? Leave your comments below...
