• This is a partial transcript from "Your World with Neil Cavuto," June 20, 2005, that was edited for clarity.

    NEIL CAVUTO, HOST: Think you have to give up your favorite foods to lose weight? Think again. My next guest ate at McDonald's (search) for 60 days straight and, get this, lost almost 20 pounds. And she did it to prove that the guy behind that documentary, "Supersize Me" (search), was, well, super misrepresenting things.

    Joining us now is Soso Whaley.

    Soso, good to have you.

    SOSO WHALEY, OWNER, LITERARY LLAMA PRODUCTIONS: Well, thank you for having me.

    CAVUTO: So, you lost this weight doing what?

    WHALEY: Well, I lost weight eating at McDonald's. And people often look at me aghast. Oh, you lost weight at McDonald's? I did. And, actually, I did it longer than that. I did 90 days and I lost almost 30 pounds.

    CAVUTO: Well, your point was originally that this guy who did the documentary just had it all wrong.

    WHALEY: Well, basically. I mean, he was eating a lot of food.

    CAVUTO: Right.

    WHALEY: The best we can figure, about 5,000 calories a day. We don't know exactly what he was eating, because he never released any good diaries.

    CAVUTO: Right. It's Morgan Spurlock.

    WHALEY: Morgan Spurlock. I didn't even see the film when I started the project, because, when I heard about it, I said, this is aversion therapy. This is just telling people, don't eat at a particular place.

    CAVUTO: But anything taken to extreme is bad, right?

    WHALEY: Absolutely.

    (CROSSTALK)

    CAVUTO: So, he was just plowing through Big Macs and double cheeseburgers.

    WHALEY: Sure.

    CAVUTO: And, naturally, you're going to gain weight — especially if you don't exercise, right?

    WHALEY: Absolutely. Right. And the thing is, he says, oh, well, I supersized. Well, out of 90 meals, they only asked him nine times if he wanted to supersize.

    This suggests to me that McDonald was already phasing out their supersize portions.

    CAVUTO: So, how did you lose weight?

    WHALEY: I stayed under 2,000 calories a day. That wasn't always easy.

    CAVUTO: Give me a typical day for you.

    WHALEY: OK. Say, I might have a McGriddle for breakfast.

    CAVUTO: Right.

    WHALEY: I like the McGriddle with bacon, egg and cheese. Maybe a glass of orange juice with that. That's about 500 calories.

    CAVUTO: But you wouldn't have a hash brown?

    WHALEY: I might. It depends. If I was going to do some roller-skating, because I do some roller-skating.

    CAVUTO: Sure. Now, lunch...

    WHALEY: Well, I might be a good girl, have a California Cobb salad.

    CAVUTO: Right.

    WHALEY: And I will use all of the dressing, because that's only 120 calories there. But, altogether, that might be about a 400, 500-calorie meal. So, I've still got about 1,000 calories left for dinner. Go for the Big Mac.

    CAVUTO: And when did have the fries, which you largely tried to avoid, you would have the small fries.

    WHALEY: No, no, I didn't try to avoid them. Oh, no, no, I had to eat all the different sizes.

    CAVUTO: Right.

    WHALEY: My favorite meal, chocolate shake with medium fries.

    CAVUTO: Oh, man. Call it a day there.

    (LAUGHTER)

    CAVUTO: So, so, you know, when you see the way fast food is vilified, you were trying to say, in moderation, everything is fine.
