听力文摘：停止吸烟会导致体重增加（在线收听）

One of the really interesting things about the nicotine in cigarettes is that it works in two ways.

香烟中尼古丁的其中一个非常有趣的特质是，它以两种完全不同的方式工作。

When you take a long drag, it acts as a tranquilizer, but when you inhale in short puffs, it acts as a stimulant. And one of the side-effects of stimulants is that they suppress the appetite.

如果你长期吸烟，那么它会起到镇定剂的作用，但如果你只吸几口，它则会成为兴奋剂。而兴奋剂的其中一个副作用则是抑制食欲。

One of the most successful ad campaigns for cigarettes encouraged women to smoke instead of eat. And the fact is that cigarette smokers do weigh less on average than nonsmokers. Research shows that quitting smoking can make you gain between five and twelve pounds.

其中一个最成功的香烟广告活动就是鼓励女士们用吸烟代替吃饭。实际上，吸烟者通常的确比不抽烟的人体重要轻。调查发现，戒烟会导致体重增加五到十二磅。

Physicians recommend moderate exercise like walking for thirty minutes, three times a week. Not only does exercise help control weight gain, it also helps ease the stressful feelings associated with quitting.

医生建议进行适当的锻炼，比如每周三次进行步行，每次步行三十分钟。运动不仅可以控制体重，而且能放松因戒烟导致的紧张情绪。

You can also try to limit alcohol and cut down on foods high in fat, but keep in mind that most experts think that it isn’t a good idea to go on a strict diet and try to quit smoking at the same time. You should focus on one health challenge at a time.

你也可以控制饮酒并减少高脂肪食物摄入，但请谨记，大多数专家不建议在戒烟的同时进行节食。你应该一次锁定一个健康目标。
