Question

Here comes a great new book. It has claimed that people can lose weight by eating anything they want, but only during a set eight-hour period. The 8-Hour Diet: Watch the Pounds Disappear Without Watching What You Eat! is co-written by David Zinczen and Peter Moore.

They argue that staying up late and eating around the clock is responsible for the high rates of diabetes (糖尿病) and obesity. Our bodies can’t process the food we eat after these hours. These calories end up where they shouldn’t, around our bellies and butts (臀部). The book claims we can lose ten pounds in a week and up to 20 pounds in six weeks, and asks that we choose any eight-hour window for eating, such as 9 am to 5 pm or 11 am to 7 pm.

Staying up and eating late may be the cause of diabetes. Simply, limiting food intake to 8 hours gives people all the benefits—without having to worry about food intake.

In the simplest terms, the 8-hour diet is a way of extending the period between our last snack and our breakfast, giving our body the chance to burn away our fat stores for the energy it needs.

Restricting (限定) the time period during which we eat makes our body burn more calories in the day. So the longer we eat, the lazier our metabolism (新陈代谢) becomes. However, if we fit food intake into an eight-hour window, our body burns more calories day and night as well as preventing diseases, such as diabetes and heart diseases.

1.According to the book, people should ______.

A. eat as little as possible    B. develop an 8-hour diet

B. if we take in food for eight hours

C. if we limit the food we eat to certain types

D. if we eat food within an eight-hour period
