If more than 30 percent above his ideal weight,he will do better to exercise before he eats. 超过标准体重百分之三十以上的人，则在饭前运动较好。

After-meal exercise takes advantage of a process called diet-induced thermogenesis. 饭后运动是利用一种称做“饮食导致热量产生”的过程来消耗热量。

This means that metabolism increases after the calories eaten. 也就是说，新陈代谢会在饭后增快，消耗所吃进的百分之七到十的卡路里。

Several studies suggest that this process increases if exercise is done after eating. 许多研究都显示，饭后运动能增强此过程的进行。
