From this:

NEW YORK - Normally sane actors have been known to gain or lose huge amounts of weight for their art. Think of Renee Zellweger in Bridget Jones's Diary. Directors, of course, never have to undergo such torture. Or so it used to be, until Morgan Spurlock had a bright idea for a film project.

The first clue to his particular misery comes in the title of his documentary, which has become the darling of this year's Sundance Film Festival. It is called Super Size Me: A Film of Epic Portions and it is a sometimes comic but serious look at America's addiction to fast food.

Spurlock, a tall New Yorker of usually cast-iron constitution, made himself the guinea pig in this dogged investigation into the effects of fast food on the body. He ate only at McDonald's for a month - three meals, every day - and took a camera crew along to record it. If a server offered to super-size his order, he was obliged to accept - and to ingest everything, gherkins and all...

[Spurlock] saw a news item about two teenage girls in New York suing McDonald's for making them obese. The company responded by saying their food was nutritious and good for people. Is that so, he wondered? To find out, he committed himself to his 30 days of Big Mac bingeing...

It sounds like a real scientifically-based film, except for the cheap effect of pigging out at McDonald's three times a day.

How many of their chicken salads did he eat? Aren't some McDonald's items healthier than others?

Add in the fact that his girlfriend is a vegan chef, and the picture of an elitist prat who brings to food what Michael Moore brings to politics is complete.
