A: why are there still so many people overweight despite the current fitness craze?
C: well, there are certain factors that effect people's size and weight.
A: what are they?
C: one study said that low-income groups have a higher percentage of over-weight people than higher income families.
C: the survey said that the low, income groups eat more junk food on a daily basis.
A: that makes sense. Probably less time to make dinner and the junk food is cheaper.
C: and junk food contains lots of fat and oil. There is one final reason why so many people are fat.
A: what's that?
C: nobody exercises anymore-not even kids! The average american home has the TV on for 6 hours a day!
A: wow! No wonder people are so fat. Say, Carl, looks like you could be doing a bit more exercising.
C: yeah, I guess so.
A: you should consider eating healthier food and getting some more exercise.
C: hey, I started a diet and lost 10 pounds.
A: so what happened?
C: well, I quit and gained it back plus 5 pounds.
A: you should have kept trying.
C: hey, Tom, did you enjoy your lunch?
T: oh, don't mention it. It was terrible.
C: what' the matter?
T: the food station was as crowded as usual. I waited for 20 minutes for my sandwish, and when I finall got it the chicken was underdone.
C: I see. You simply can't blame the server for this.
T: yes, I know. Fast food is so popular in this district.
C: that's true.
T: anyway, how was your luch, Catherine?
C: it was good. I brough lunch from home today.
T: you did? I thought you must feel right at home here as we get as many fast food restaurants as you do in America.
C: well, I personally don't like then because i don't believe they are healthy.
T: i guess you're right. More often than not, people go there only for convenience. The foods may taste good, but generally speaking, they are high in calories, salt and fat.
C: yes. I am wondering that you must believe fast food is your lifestyle, don't you?
T: you bet. Almost all top brands such as McDonald's and KFC are from America.
C: well, actually two-thirds of Americans may avoid these places.
C: yeah, it's hard to believe but true.
