LABRADORS & HUMANS SHARE OBESITY GENE?! British researchers studying 250 Labradors found that some dogs can’t stop eating thanks to a gene called DENND1B—which, surprise, also exists in humans and is linked to overeating and weight gain. Dr. Eleanor Raffan, University of Cambridge: “Owners of slim dogs are not morally superior. The same is true of slim people. If you have a high genetic risk of obesity, then when there’s lots of food available you’re prone to overeating and gaining weight unless you put a huge effort into not doing so.” Scientists say dogs and humans pack on pounds for similar reasons, making Labradors a great model for studying why some of us can’t resist that extra snack. The research could help develop new treatments for obesity, but in the meantime, maybe cut back on the treats—for both you and your pup.
