The perfect diet

Just met up with a friendgirl from abroad who's staying with me over the weekend. Gosh, had she lost a lot of weight! Put me to shame, with a measly 7 kg's loss or so. Then I learned about her secret diet. Just fall on your face, preferrably polishing the pavement with your teeth, and voilà. The perfect diet. The fact that you have to eat through a straw and live with a crooked tooth is a small price to pay.
