I'm on the greatest diet in the world. I'm losing weight like nobody's business and I don't even exercise. All I do is sit on my butt and eat everything that's put in front of me, no matter what time of day or night. The only drawback to this diet is that it's incredibly expensive. It's the frequent-flier diet.
Frequent fliers are the only people with any shot at losing weight, because airplane food is the only real portion control. I've been flying all over recently, on a book tour, and have lost almost 10 pounds in three weeks. In one cross-country flight, five hours in duration, the most I got to eat was two bags of peanut-and-sesame things. The total for the peanut grossness was only 80 calories. Plus the little silver bags are impossible to open, since they're made of Mylar from the toughest party balloons ever, or maybe NASA space suits. All that struggling with the bag increases your metabolism, so you get to factor that in, too.
