Thin people,however,suffer from the opposite:They have to make a great effort to gain weight.Ethan Sims,of the University of Vermont,got prisoners to volunteer to gain weight.In four to six months,they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent.But months after the study ended,they were back to normal weight and stayed there.
This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.
The findings also provide evidence for something scientists thought was true-each person has a comfortable weight range3.The range might be as much as 9kg.Someone might weigh 60-69kg without too much effort.But going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.
