The researchers believe that this is because we are more aware of our gender when around the opposite sex and women restrict their eating to appear “more feminine” while men eat more around women to appear “more masculine”.

研究人员认为这种现象可能是因为与异性吃饭的我们会更注意自己的性别，女人会因为和男性朋友吃饭而表现得更加有女人味，同样的，男人也会因为和女性朋友吃饭而显示出自己的男性魅力。

3. Pay with cash

用现金付款

According to a study by researchers at Cornell and Binghamton Universities, your credit card could be making you fat. While it has been known for a while that we are more likely to splash the cash when we are paying by card than by coins, the study results found that paying with plastic also has disastrous results for your waistline, as people are more likely to buy junk food and “vice” products – which tend to be impulse purchases – when paying by card. To keep off the pounds and save yourself some money, draw out enough cash for the day and then leave your cards at home.

来自康奈尔和宾厄姆顿大学的研究表示，你的信用卡会使你变胖哦！大家都知道，当我们付款时，更倾向于银行卡而不是现金，但是研究表明，这对你腰上的肥肉增长有灾难性的诱发作用。因为人们在用信用卡时，更易因冲动买一些垃圾食品。为节约消费，避免体重上升，把你的卡放家里，再去取点现金做准备吧！
