The Real Price of a Big Mac

You mentioned your girlfriend. She's a vegan, right?

[Laughs.] My girlfriend is a vegan, yeah. How ironic is that? We've been together about four years now--she was there from the beginning. She was in the movie.

How did she handle it?

She wasn't pleased. She wasn't real happy. But she was so supportive and she's always been very supportive of me and the things that I do. This was one of those things she didn't really like--she didn't really agree with me eating the food--but she was like, "Listen, I understand what you're trying to do." And she was great. She was very funny in the movie.

McDonald's has argued that the premise of your film is unfair, that its stores offer a wide array of food.

It's a very extreme route I took. That's the other argument that's made: nobody's supposed to eat this food that often, no wonder all these bad things happen. But the thing is, there are people who go to these restaurants and do eat very heavy fat-laden foods and sugar-laden foods every day. Maybe not every day but six days a week or five days a week. And while they may not get the dramatic impacts that I had--things may not happen at such an exaggerated rate--these things will happen over the long run if they don't exercise, if they're not taking care of themselves. You have to exercise a lot to run off a super-sized Big Mac meal. You're talking about 1,500 calories. You eat 1,500 calories, you have to run for three or four miles, for 45 minutes to an hour.
