看别人吃“垃圾食品”可以帮助我们减肥

Watching others eat junk food can make us feel full more quickly when we eat it ourselves， according to experts. We dig into the science of this “see food” diet.

According to neuroimage studies， the mere sight of someone being hit by a hammer will fire up the neural networks in our brain that are associated with pain. As a result， these images trigger emotions and behaviour consistent with feelings of pain.

Such effects also extend to food consumption. Some studies have even indicated consumption imagery could cause people to wrongly recall having eaten the food on display.

With our research， we decided to test if the effect holds when people see someone else eating in an ad. We invited 132 dieting students at our lab at the Grenoble Ecole de Management to watch an ad. Half of them saw an M&Ms advertisement brimming with consumption imagery： sweets， colors， and a person eating them. The other half of the students saw an ad with two animated M&Ms at a supermarket till， devoid of consumption imagery. We then gave each student a 70g cup of M&Ms and asked them to eat to their hearts content. Among the students， those who saw the M&Ms advertisement containing consumption imagery ate fewer sweets than those who saw the ad without.

So the mere sight of someone eating junk food or of junk food alone is enough to put dieters off it， at least for a time.

Indeed， dieters imagining themselves eating junk food consciously associate it with a failure to reach their weight loss goals.

Today people prioritize their wellbeing more and more. If you are one of the many who set dieting and healthier eating as their number one resolution for 2023， our tip to you is that you resist the urge to cover your eyes when seemingly tempting ads pop up. Instead， engage with them fully. As science would have it， this might just cut down your unhealthy eating habits.

1. B。解析：推理判斷题。材料第二段提到“the mere sight of someone being hit by a hammer will fire up the neural networks in our brain that are associated with pain（仅仅是看到有人被锤子击中，就会激活我们大脑中与疼痛相关的神经网络）”，由此可知，本段例举了一个类似的效应。故选B。

2. D。解析：词义猜测题。根据上下文，材料第四段中带下划线的词组所在的句子大意应为：另一半学生在超市的收银台看到了带有两个M&M巧克力豆的广告，没有消费意象。由此，“devoid of”应译为“没有”，与上一句中的“with”形成实验研究的对照。故选D。

3. A。解析：推理判断题。根据材料第四段最后一句中的“those who saw the M&Ms advertisement containing consumption imagery ate fewer sweets than those who saw the ad without”，我们可知，那些看到含有消费意象的广告的人比那些没有看到的人吃的巧克力豆更少。因此，那些看到含有消费意象的M&M广告的人更容易摆脱甜食，并减肥成功。故选A。

4. C。解析：细节理解题。根据材料最后一段中的“resist the urge to cover your eyes when seemingly tempting ads pop up”“engage with them fully”，我们可知，作者建议大家在看似诱人的广告出现时，要克制住遮住眼睛的冲动，与它们充分接触。据此，C选项“想象你的嘴唇伸向垃圾食品”这一做法是有利于节食的，故选C。
