Can you remember what you ate yesterday? If asked, most people will be able

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. [br] What does the author suggest policymakers do about obesity?
选项 A、Remind people to cut down on snacking.
B、Make sure people eat non-fattening food.
C、Ensure people don’t miss their main meals.
D、See that people don’t stick to the same diet.
答案 B
解析 推理判断题。定位句指出，在政策方面，我们需要关注那些让人们容易摄人更少卡路里的选择。如果人们不知道自己吃了多少，那他们就真的很难坚持节食了。此外，我们应该寻找新的方法来确保人们的饮食不会对他们的腰围产生太大影响。由此可见，作者认为，政策制定者应该引导人们多吃一些卡路里较少的食物，使之尽量减少对体重的影响，故答案为B)。
