A British research team has discovered a specific gene, called FTO, of which a variation may be responsible for the tendency to become obese. Published in the most recent edition of the journal Science, the study shows that, of the 38,000 participants (mostly white Europeans), those who had one copy of this particular FTO variation had a 30-percent greater risk of being obese; those with two copies had closer to a 70-percent greater risk.
Although scientists have discovered genes with identifiable functions like those related to appetite and calorie burning, they do not yet know what exactly FTO does for the human body.
