句群4
【4】Don’t forget the clock-or the radio. People who eat slowly tend to consume about 70 fewer calories（卡路里）per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.
参考译文
不要忘记钟或收音机。与那些吃饭匆忙的人相比，吃得慢的人每餐会少摄入70卡路里。开始记录用餐时间吧，尽量让正餐的时间至少维持在30分钟。而且当你开始这样做时，一定要好好坐着吃。若你需要某些外力帮你慢下来，就播放一点让人放松的音乐，那会减少你吃饭匆忙的可能性。
