A group of experimental subjects participated in an "intermittent fasting" study, under which they ate all of their food for the day within six hours of waking up. The subjects consumed the same number of calories as they normally did throughout an entire day and did not change their exercise patterns. Nearly all of the subjects lost a significant amount of weight during the study. It can thus be concluded that eating all of one's food within a relatively short period of time causes the body to burn more calories.
Which of the following would be most useful to establish in evaluating the argument?
A. Are people more likely to consume low-calorie foods early in the day than at night?
B. Is the practice of intermittent fasting safe and free of major side effects?
C. Are most people able to consume as many calories within an interval of six hours as they normally would over the course of an entire day?
D. Will people following an intermittent fasting protocol feel substantially hungrier than those who space out their meals more regularly?
E. Does the body burn calories faster when food is eaten earlier in a person's waking hours than when it is eaten later?
E
我又怀疑这道题有什么常识是我不知道的。。。
结论是：短时间内把一天的食物全部吃完会使身体燃烧更多的卡路里。（前文说运动量不变，摄入量与实验前的一日三餐相同）
A. 无关
B. 与结论无关
C. 反驳前提，无关
D. 与结论无关
E. 燃烧更快和燃烧更多能是一回事吗？是我常识欠缺吗？
曼哈顿解释：
(E) CORRECT. This could provide an alternative explanation for the study result. Perhaps people burned more calories simply because they ate earlier in the day and not because of the condensed time period. If this wouldn’t happen in the evening, perhaps the author’s conclusion is not true in general. For instance, perhaps consuming all one’s calories in the last six hours of the day would lead to weight gain, not loss. In that case, it wouldn’t appear that simply eating over a reduced period of time lead to increased calorie burning.
