据外媒报道，近日《临床研究杂志》刊登一项研究表明，有些肥胖症不是吃太多或不运动而造成的，真正原因是基因。
突变基因控制传送给大脑特定区块的信息，这部分的大脑区块负责控制食欲和决定燃烧脂肪的多少。专家认为，确认这个基因对人体造成的效应，能更快开发抵抗肥胖症的药物治疗。

Two studies zero in on DNA-based drivers of weight. Is obesity written in our genes?
In two separate papers, published in the journal Science and in the Journal of Clinical Investigation （JCI）， researchers describe new genetic factors that could explain weight gain in some people. In the Science study, researchers at Boston Children's Hospital studying mice found a rare genetic mutation that prevented the animals from burning off fat calories. They also found the same gene was mutated in a group of obese people. And a team based at University College London reported in JCI that a specific form of a gene previously linked to obesity, FTO, can increase craving for high-fat foods.
