You hear this：“No Wonder you are fat．An you ever do is eat．”You feel sad：“I skip my breakfast and supper．I run every morning and evening．What else can I do?”Basically you can do nothing．Your genes，not your life habits，determine your weight and your body constantly tries to maintain it．
Albert Stunkard of the University of Pennsylvania found from experiments that，“80 percent of the Children of two obese parents become obese，as compared with no more than 14 percent of the offspring of two parents of normal weight．”

（第4段） 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 （说服）prisoners（犯人） to volunteer to （自愿...）gain weight(增肥， 体重增加) ．In four to six months，they ate as much as they could．They succeeded in increasing their weight by 20 to 25 percent. But（但是） months after the study ended（结束），they were back to（恢复到） normal（正常的） weight and stayed停留在那里 there.
