Gene called FTO is carried by almost half of the British public and recently discovered a few years ago. Although researchers know that this gene can cause a person fat, but researchers do not yet know how the mechanism of the gene.
Now, researchers found that the gene makes people always feel hungry and make it difficult when dieting. People who carry two gene FTO obesity risk 70 percent higher than those who did not have the gene.
While those who only carry one FTO gene have a 30 percent higher risk of developing obesity. The results obtained after the researchers looked at samples of young men who have the FTO gene and did not have FTO gene.
When do the MRI scans, the researchers also found that people who have the FTO gene are also more likely to think of fatty foods and sugary foods. Researchers say that some people are biologically programmed to eat more.
"Not only the level of ghrelin in the blood that makes them feel always hungry, but their brain responses to food are also very different," said Dr. Rachel Batterman, lead researcher from University College London, as reported by the Daily Mail.
Even so, this DNA could still be countered if one wants to prevent obesity. Batterman explained that hunger is caused by ghrelin could still be reduced by exercise such as running, cycling, or eating foods that are high in protein.
The researcher also believes that this discovery could help them to find new ways of preventing obesity or making drugs for those who have the gene FTO hungry.
