问题 Bad eating habits, increased food availability, increasingly sedentary lifestyle and reduced physical activity are the first four causes of the obesity epidemic. [br] Less sleep can gain us weight, because it raises our leptin, which triggers us to eat more.

选项

答案 N

解析 本题涉及到Less sleep与leptin的关系,从而将题目出处定位到Not Enough Sleep部分。该部分第三段末句提到,睡眠不足时,Leptih显示过饱的激素会下降而ghrelin,显示饥饿的激素则会增加,这会促进我们的食欲。所以增加的是ghrelin而不是leptin。故答案为N。
