问题     Can you remember what you ate yesterday? If asked, most people will be able to give a vague description of their main meals: breakfast, lunch, dinner. But can you be sure you’ve noted every snack bar in your car, or every handful of nuts at your desk? Most people will have a feeling that they’ve missed something out.
    We originally had this suspicion back in 2016, puzzled by the fact that national statistics showed calorie consumption falling dramatically over past decades. We found reliable evidence that people were drastically under-reporting what they ate.
    Now the Office for National Statistics has confirmed that we are consuming 50% more calories than our national statistics claim.
    Why is this happening? We can point to at least three potential causes. One is the rise in obesity levels itself. Under-reporting rates are much higher for obese people, because they simply consume more food, and thus have more to remember.
    Another cause is that the proportion of people who are trying to lose weight has been increasing over time. People who want to lose weight are more likely to under-report their eating—regardless of whether they are overweight or not. This may be driven partly by self-deception or "wishful thinking".
    The final potential cause is an increase in snacking and eating out over recent decades—both in terms of how often they happen and how much they contribute to our overall energy intake. Again, there is evidence that food consumed out of the home is one of the most poorly recorded categories in surveys.
    So, what’s the message conveyed? For statistics, we should invest in more accurate measurement options. For policy, we need to focus on options that make it easy for people to eat fewer calories. If people do not know how much they are eating, it can be really hard for them to stick to a diet. Also, we should be looking for new ways to ensure what people eat wouldn’t have much impact on their waistlines. If this works, it won’t matter if they can’t remember what they ate yesterday.
What did the author suspect back in 2016?
选项 A、Calorie consumption had fallen drastically over the decades.
B、Most people surveyed were reluctant to reveal what they ate.
C、The national statistics did not reflect the actual calorie consumption.
D、Most people did not include snacks when reporting their calorie intake.
答案C
解析 推理判断题。定位段指出，早在2016年他们就有了这种怀疑，因为国家统计数据显示，在过去几十年，卡路里消耗量大幅下降，这让他们感到困惑。有可靠的证据证明人们严重地漏报了他们吃的东西。由此可见，有证据显示人们漏报了自己摄入的食物，因此作者怀疑国家统计局数据的真实性，故答案为C)。
