据《生命时报》报道，澳大利亚科学家的一项研究表明：如果人类时常保持两分饥饿，其寿命可最多增长30%。报道说，在年轻时经常吃撑，危害甚至会影响两代人的健康。哪怕是短期暴饮暴食，不仅体重会上升，对全身的伤害也会持续多年。
Why do we eat so much?
为什么会吃多？
One reason is buffet lunches – they need no explanation. Business dinners that last for hours also encourage people to eat too much. Dinner parties with friends are also culprits, as being in a good mood gives you an appetite. Eating too quickly because you are busy can also be a problem. It takes 20 minutes for the brain to receive a warning of overeating, so wolfing lunch in 10 minutes is not a good idea. Finally, skipping meals due to work pressure can lead to binge-eating in the evening.
原因之一是自助餐，这无需多言。持续时间过长的商务宴请也会让人吃多。与朋友聚餐也是罪魁祸首，因为心情好会让你胃口大开。工作太忙吃得太急是个问题。大脑接到吃饱了的信号需要20分钟，所以10分钟的狼吞虎咽不是个好主意。最后，由于工作压力而不吃饭会导致晚上暴饮暴食。
What wrong about overeating?
吃多会造成什么问题？
“Taking in half the food that your stomach can contain is enough for you to survive. Eating too much places a burden on your organs and causes many health problems,” heath education expert Hong Shaoguang said.
健康教育专家洪昭光说：“每天摄入的食物，只需要达到胃的容量的一半，就足够人一天所需了。否则，只会让机体超负荷运转，造成一系列健康问题。”
