Clearly, Felix's plan does more harm than good, but extreme calorie reduction diets aren't the only regimens promising to shed weight fast.

显然， 菲利克斯的计划弊大于利，但极度减少卡路里的饮食并不是唯一有望快速减肥的方案。

What is necessary if the same pathways are to be recruited without the calorie reduction is an understanding of what other cues can have the same effect.

如果要在不减少卡路里的情况下招募相同的途径，那么有必要了解哪些其他线索可以产生相同的效果。
