Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged.  They will thus burn significantly fewer calories at the new weight than do people whose weight is normally at that level.  Such newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic rate.

The conclusion of the argument above depends on which of the following assumptions?

(A)  people who have dieted down to a new weight tend to continue to consume substantially fewer calories than do people whose normal weight is at that level.

(B) The metabolisms of people who are usually not overweight are much more able to vary than the metabolisms of people who have been very overweight.

(C) The amount of calories that a person usually burns in a day is determined more by the amount that is consumed that day than by the current weight of the individual.(D) Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.(E) Because of the constancy of their metabolic rates, people who are at their usual weight normally have as much difficulty gaining weight as they do losing it.

答案是A。不懂consume和burn有何区别？

我懂你的纠结，我也纠结了好久。看答案的意思，consume在这里应该是吃进去东西的吃，burn才是燃烧消耗卡路里。所以才会出现解释的 consume fewer卡路里是吃的少的意思。

不对，应该吃的多 burn的少才能胖回去啊。consume和burn难道是一个意思？那不是重复一遍了 有何意义？
