1. Eat in front of a mirror

1、对着镜子吃东西

Researchers from Arizona State University and Erasmus University Rotterdam found that watching ourselves eat can be a powerful trigger to consume less. During their experiments, the researchers placed a mirror in front of participants and found that those eating in front of a mirror consumed less food. The researchers believe that this is because seeing ourselves eat makes us more aware of our bodies and that we do not want to watch ourselves overeat.

来自亚利桑那州立大学和荷兰鹿特丹大学的研究人员发现，观察自己吃东西是控制食欲的给力助推器。研究人员在实验中发现，在有镜子在面前的参与者吃东西会减少。他们推测原因是我们看着自己会将注意力更多地转移到自己的身形，就不愿意自己过度进食了。

2. Choose male eating companions

2、选择与男性朋友一起吃饭

If you want to cut down on your food consumption when dining out, research suggests that opting¹ for male eating companions could help you to consume less food. Researchers from Indiana University of Pennsylvania and the University of Akron found that both men and women consumed fewer calories when dining with men than with women.

如果你想在外出吃大餐时减少自己的进食量，研究建议选择一个男性伙伴一起吃饭吧，这样会有你想要的效果。来自宾州印第安纳大学和阿克伦大学的研究人员发现，不管男人还是女人，和男性朋友一起吃饭都比和女性朋友吃饭能更多地减少体内卡路里的摄入。

The researchers believe that this is because we are more aware of our gender² 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

3、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 disastrous³ results for your waistline, as people are more likely to buy junk food and “vice⁴” 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！
