“One of the key hallmarks of addiction is impulsivity,” said Gearhardt, now an assistant professor at the University of Michigan.
“We were theorizing that if food addiction is really a thing, then our measure [the Yale Food Addiction Scale] should be related to impulsive action.”
Clinical psychologist Dr. James MacKillop, whose lab was behind the study, believes that therapies used to treat addictive drug behaviors could help people who suffer from addictive eating habits.
“Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise,” MacKillop said. “It seems like craving management or managing acute desires to eat would have a natural fit within the domain of skills a person would need to eat healthily.”

美国乔治亚大学的研究人员进行的一项新研究表明,性格冲动的人更易患暴饮暴食症。
这项研究发现,表现出性格冲动的人不一定都面临着超重问题,但冲动性格和过度饮食有着必然联系,而过度饮食就会导致不健康的体重。
食物成瘾已与药物上瘾无异。有研究发现品尝美味之后释放出的多巴胺与人们使用其他上瘾的物质后释放的多巴胺有关联。
冲动行为包括多种性格特点。在这项研究中,这其中两个特点——急躁和缺乏毅力尤其与食物成瘾及较高的体重指数联系在一起。
