Todd: Devon, I've been putting on a few pounds and you're quite a lean fit guy.

Devon: Well, thank you.

Todd: What do you recommend? What can I do to lose weight?

Devon: Well, I exercise a lot. I go running at least three times a week. More than that, I enjoy playing sports. Different sports use different muscles and all of it helps to lose that weight that you might have gained.

Todd: Yeah. Actually, one of the problems is that I actually exercise a lot.

Devon: Do you?

Todd: Yeah, so maybe it's my diet.

Devon: It could be and so in that case you might want to eat something perhaps morenutritious or maybe even less of what you do eat. Maybe, I eat three meals a day and I try not to snack in between. No potato chips. No popcorn. No candy bars.

Todd: That's pretty tough!

Devon: It is tough but......Well, I must admit that I cheat every once in awhile but...

Todd: Ok, I'll give it a try. Actually, you see my problem is that I like junk food. I have to choose, either I eat less or I eat a better diet. What do you think is more important?

Devon: I think that if you are exercising then you should just eat what you want and eat less.

Todd: Eat less. OK. This is going to be tough.

Devon: Well, I have no doubt that you will do the best that you can.

Todd: Alright! Thanks a lot Devon.
