Researchers say they may have found a gene that helps people stay thin, even if they eat a lot.
In a study published in the journal Cell, scientists used data from more than 47,000 people in Estonia aged 20 to 44 to try and find a gene linked to being thin.
Senior author Josef Penninger, from the University of British Columbia, explained that there are people who can eat almost anything they want and don’t exercise a lot, but are still healthy and don’t gain weight. "We all know these people: it's around 1% of the population," he said.
Penninger’s team used the Estonian Biobank to compare data from healthy thin people with that of normal-weight people. They found that thin people had differences in what is called the ALK gene, which may stop them from gaining weight.
The research team also found that flies and mice that didn’t have the ALK gene could stay thin even when they ate too much. And mice without the ALK gene had a lower body weight and less body fat even if they ate the same food and exercised just as much as normal mice.
The researchers say that targeting the gene might help scientists stop people from becoming overweight.
 
Penninger said that they could turn off the gene or change how it works, and see if that helps people stay thin.
 
🌏Summary
研究人員表示,他們可能找到一種基因,讓人們即使在吃很多的情況下,還是能保持苗條的身材。發表在科學期刊《細胞》中的一份研究裡,科學家使用愛沙尼亞年齡介於 20 歲至 44 歲間 47,000 多人的數據,發現一種基因與苗條有關。英屬哥倫比亞大學的資深作者 Josef Penninger 解釋,就是有人可以吃下幾乎所有他們想吃的東西,又沒有大量運動,不只不會變胖,還可以維持身體健康的狀態。「我們都認識這樣的人:這些人大約佔總人口數的百分之一。」研究人員表示,把目標放在關掉這種基因,或是改變其運作的模式,也許可以幫助人類保持苗條。
