Some people can't be fat

Scientists said there was a clear association between gene and obesity. Accordingly, people with two versions of a fat gene will have 70% more risk of obesity than those without this gene, and about 3 kg heavier.

The study was carried out by 40,000 people from Peninsula Medical School and Oxford University. This result proves that despite the best efforts to change diet, exercise, some people still have difficulty losing weight, the culprit is due to genes. According to the authors, the work will help people better understand obesity and help prevent this epidemic.

Obesity is associated with the risk of type 2 diabetes. Investigators first identified the FTO gene when investigating the genetic differences in people with type 2 diabetes and those without. Those with type 2 diabetes are more likely to have a variant of the FTO gene, which is also associated with weight gain.

Next, the team searched in a study of more than 40,000 people to identify the FTO gene body and determine that it was related to weight.

Those who carry a version of FTO gene increase by 30% the risk of obesity compared to those who do not have a gene version. Those who carry 2 copies of this gene variant increase their risk of obesity by 70% and weigh about 3 kg on average compared to those without a copy.

Professor Andrew Hattersley at Peninsula Medical School identified the results of why two people seem to be alike and practiced the same, but one in two still has more difficulty losing weight than the other.
