Scientists say they have identified the gene for thinness, one that predisposes some people to not gain weight, regardless of their style of life.
Authors of different origins in the international have signed a study published Thursday in the journal Cell (or “Cellule” in French, NDLR). The study in question sets out a finding that variants of the gene said ” ALK ” lead some individuals to be less fattening than others.
“We all know these people : it is about 1% of the population,” said Josef Penninger, one of the co-authors of the study and professor of medical genetics at the University of British Columbia, Canada. His comments, taken from a press release, have been relayed by the New York Post.
“They can eat what they want and keep their metabolism healthy despite everything. They eat a lot, they don’t do squats all the time, but don’t just take no weight, ” said Dr. Penninger.
The team of this doctor in genetics, analysed the DNA of more than 47 000 people aged 20 to 44 years and found this to be a single variant of the gene ALK, which has already gained the reputation of having a role in the development of tumors due to its propensity to mutate when living with cancer.
Penninger and other researchers believe that it might be possible that mutations in a gene called ALK are behind the weight gain in some cases and could be targeted in the fight against obesity.
But before you consider to manipulate its genetics, the low proportion of the population that does not have a gene ALK ” favorable “, say, should focus on a healthy lifestyle.
Last February, the world Bank called on the poor and developing countries, the most affected by overweight and obesity, a tax on food bad for health as too much fat, too sweet or too salty, according to a report released Thursday.
