Shinji：Mike， why are so many Americans overweight?

Mike： Well， that's a good question， Shinji. You'd think that with the current fitness craze (健美热)in the U.S. there wouldn't be so many over-weight Americans.

Shinji： Just how many people are overweight?

Mike： About 40% of Americans are overweight. Interestingly， one study said that low-income groups have a higher percentage of over-weight people than higher income families.

Shinji： Are there any other factors like that in the study?

Mike： Yes. The study also said that the hotter the climate， the lower the percentage of obese (过于肥胖的)people……

Shinji： That makes sense (有道理，说得通)。 When it's hot， you usually don't feel like eating a lot.

Mike： Is that why Japanese people are typically skinnier than Americans?

Shinji： Well， our diet has a lot less fat and oil than American food. And Americans eat a lot more meat than we do.

Mike： You're right. And we also eat more sugar and junk food. But there's another reason why so many Americans are fat.

Shinji： What's that?

Mike： Nobody exercises anymore - not even kids. The average American home has the TV on for six hours a day!

Shinji： Wow! No wonder you Americans are so fat. You don't get enough exercise. Say， Mike， aren't you getting a little bigger in the waist?(你的腰围是不是又粗了一点儿?)

Mike： yeah， I guess so.

Shinji： you really need to watch what you eat and get some exercise.

Mike： Hey， I started a diet and lost 10 pounds.

Shinji： So what happened?

Mike： I quit and gained it all back plus 5 pounds……

Shinji： What's that supposed to mean?

Mike： Look in the mirror， man. (老兄，照照镜子去吧)
