A new study claims that people who suddenly start fighting the flab while they're in steady relationships are secretly preparing to drop their other halves, Daily Mail reported.

Happy couples don't worry about their expanding waistlines because there is less pressure to look attractive, sociologists claim.

University of Heidelberg professor Thomas Klein said the warning signs could include a sudden obsession with the gym or getting involved in sports and diets.

"When you are on the lookout for a new partner people try to be as thin and attractive as possible," Klein said.

Consequently, when one half in a relationship starts slimming down, it can be interpreted as "preparing for the partner market."（点击英国《每日邮报》查看原文）

节食的人或想另觅新欢

       据英国《每日邮报》报道，有研究称，拥有稳定恋情的人忽然开始减肥，多半是在秘密的为甩掉另一半做准备。

       德国海登堡大学的托马斯•克雷恩教授说，其中的危险信号包括忽然很迷恋健身房，或是进行各种运动以及开始节食。

       社会学家表示，幸福的伴侣不会担心腰身变的越来越粗，因为他们想要保持吸引力的压力较小。

       “人们要寻找新伴侣时总是希望能尽可能看起来苗条迷人，”克雷恩说。

       其结果就是，当一方开始瘦下去时，就可以理解为他/她正在为寻找新欢做准备。
