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.
A: why?
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.
