An International group of scientists is claiming to have finally solved the fat-boosting gene mystery, a flaw that had been putting many lives at higher risks of obesity (with approx one in six people).

Experts have recently mentioned about a version of an obesity gene called FTO, which they said, is linked with the bigger-size belly. Until now, scientists were clueless about the reason which was triggering the problem of obesity but the recent finding have solved the mystery.

The above facts were revealed with the help of the study that was published in The Journal of Clinical Investigation recently. It thoroughly explained how the gene FTO made fatty foods more tempting to the people and side by side altered their levels of the hunger hormone ghrelin too.

According to the knowledge provided by the Obesity experts, the drugs that claim to be targeting ghrelin might reduce weight gain. They confirmed the existence of a strong family link with obesity, following which, they concluded that a person's genetic code could play a major role in the risk of putting them prone to overweight.

The study was done by the researchers at University College London. After testing two groups of men with normal weight, they found one group with the high-risk FTO genes whereas the other one was low at such risks. They concluded that the higher levels of the hormone makes people hungry and their ghrelin levels also climb more quickly.
