W: Is that all?

M: Yes, I'm on a diet, and my doctor told me that I should lose some weight because I'm too heavy. That's not healthy.

W: How do you feel?

M: I feel fine; in fact, I've never felt better. Furthermore, some of my old clothes would fit me if I lost about 40 pounds.

W: How long will that take you?

M: Well, I've just started my diet, so it may take me six months to get down to my proper weight.

W: Do you plan to eat nothing but salads for six months?

M: No, I'll be able to eat fruit and certain meats and dairy products, but most important, I should never eat anything between meals and I should not eat anything containing sugar.

W: Then you probably won't want to try the delicious pastries they serve here. I understand the head cook is an excellent pastry chef.

M: Now that you mention it, I may have two or three of these delicious not as I usually have five or six.
