To find whether the FTO gene affects on burning calories or appetite, the researchers studied more than 3,000 children cases aged 8 to 11.

The children that were found with copies of the gene’s unsafe variant had fewer chances to have their hunger ‘switched off’ when they must be full.

In Caucasian populations, FTO is counted as the first common gene that is related to obesity.

In some recent studies it was shown that those adults who had two copies of the higher risk variant of the gene were 3kg heavier on average basis while adults who had single copy were 1.5kg heavier than adults who didn’t have that gene.

The researchers from, King’s College London and University College London and the Institute of Psychiatry are working to know more about these genes.

In the study, the researchers offered a questionnaire to parents in and they were asked about the eating habits of their children and they examined whether there was a difference in appetite according to height, weight and waist circumference measurements in those children who aged 8 to 11 and had a higher risk gene variation.

They noticed that the children who had higher risk version of the obesity gene were found with overeating and they couldn’t easily recognize whether they were full or not.

Regardless of sex, age, social-economic background the scientists found the same effect of the gene on appetite.

According to lead researcher Professor Jane Wardle, “ It is not so that people who have the risky variant of gene become overweight but these people are automatically tended to over eating.”
