The first question you might ask "Why should I fast?" A thorough answer to that question could comprise an entire book. The short answer is that fasting helps the body to normalize itself.

首先你会问：“我为什么要禁食？” 对这个问题彻底完整的回答可以包含一整本书。简短的回答是：禁食有助于身体保持正常。
Think about what happens when you go to sleep at night. Your body immediately goes about the tasks of repair and recovery (as much as possible) from the wear and tear of the day's activities. A renovation takes place in your brain and throughout your entire body that enables you to arise refreshed and raring to go the next day.

想想你晚上睡觉时身体在发生什么。你的身体立刻进行尽可能多的一些修补和恢复的工作，消除白天的疲劳和紧张。你的大脑以及整个身体都在进行革新，使你第二天恢复体力和精力。
The restorative power of a night's sleep involves many factors, and the process is not completely understood. But one factor that definitely helps facilitate this process of rejuvenation is your nightly fast. While you are sleeping each night, you are not eating—you are not adding to your body's digestive work. This period of digestive rest allows your body to devote more of its energy to its nightly restoration.

晚上睡觉的这种身体恢复能力包含很多方面，这一过程并没有完全被人们所认识了解。但是有一个因素肯定会有助于这一恢复过程，那就是晚上禁食。你每天晚上睡觉时，你不吃东西——不给你的身体增加消化工作。消化系统的休息有利于你的身体把更多的能量用于晚间的恢复。
You probably know from experience that eating a heavy meal late at night interferes with the quality of your sleep and leaves you feeling groggy the next day. Heavy eating late at night, much like heavy drinking late at night, can leave you with a hangover.

从你自身的经历中你会有体会，当你晚上吃得太多会影响你的睡眠质量，第二天也感觉昏沉无力。晚上吃太多和喝酒太多一样，会使你宿醉。

Abstinence from food at night facilitates the process of biological renewal, allowing your body to proceed with its repairs and restorations. Of course, one does not remain asleep throughout a fast, but when fasting is combined with rest, your body treats it as an extended period of renovation and renewal.
During fasting, your senses become more acute, including taste, smell, and hearing. Even sight has been known to improve during a fast, although that does not always happen.

晚上节制饮食有助于生物性的新陈代谢，使身体更好的恢复体力。当然，在禁食期间并不能保证你的身体一直睡着，但是当禁食和休息相结合的时候，你的身体就能得到充分的休息。在禁食期间，你的身体也变得更加敏锐，包括味觉、嗅觉和听觉。甚至视觉在禁食期间也会有所提高，尽管这并不总是发生。
