Researchers have found that when wery overweigh 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.Thus newly thin persons will,therefore,ultimately regain weight until their body size again matches their metabilic rate.
a) Relatively few very overweight people who have dieted down to a new weight tend to contine to consume substantially fewer calories than do people whose normal weight is at that level
e) Because of the constancy of their metabolic rates,people who are at heir usual weight normally have as much difficulty gaining weight as they do losing it.
我知道该选a，但为什么不选e呀，觉得e是从根本上说明了问题呀
