If you want to get slim, you may want to shed some of your larger friends, a new study suggests。

交错朋友伤身也伤心 想甩肉先甩胖朋友(双语)

　　Researchers from Loyola University found students were more likely to gain weight if they had friends who were heavier than they were, the Daily Mail reported。

　　However, they were more likely to either slim down, or at least gain weight at a slower pace, if their friends were leaner than they were。

　　Dr David Shoham said the results could help them develop better ways to treat obesity with teenagers."We should not be treating adolescents in isolation," he said。

　　新研究发现，想变苗条就得甩掉一些胖朋友。

　　据英国《每日邮报》报道，洛约拉大学的研究人员发现，如果朋友比自己胖，这样的学生就更容易长胖。相反，如果朋友比自己瘦，他们就更可能瘦下来，至少长胖的速度会比较慢。

　　大卫·索汉姆博士表示，该研究结果有助于他们找到治疗青少年肥胖的更好方法：“我们不应该再把青少年孤立起来治疗了。”
