Zorba Paster is a little annoying, but I agree with his advice on eating less calories and exercising more. Similarly, What Should We Eat? from the NYT By DENISE GRADY

In a word -- less.
...
Counting calories may seem like an old-fashioned approach, given the trendy diets that abound these days, but food is fuel, the body burns it and the laws of physics still apply. For adults, one way to estimate how many calories you need in a day just to maintain your current weight is to divide your weight in pounds by 2.2 (to convert it to kilograms) and then multiply the results by 30. Using that formula, a 150-pound person needs about 2,045 calories a day. Men usually need a bit more than women, and active people more than sedentary ones.

People who start paying attention are often surprised at how fast calories add up, and, unless they eat a lot of vegetables, how little food provides 2,000 calories. A corn muffin or a large serving of French fries can have more than 400 calories, for instance, a cheesesteak sandwich more than 800, two tablespoons of salad dressing close to 200, a chocolate sundae more than 1,000.

To lose one pound, it is necessary to cheat the body of 3,500 calories -- say, 500 a day for a week, or 350 a day for 10 days. That means either eating less or burning off calories by exercising.

I can't believe people are still messing around with fad diets and apparently refusing to exercise. On the other hand, the article also talks about living longer by eating a lot less. That's not worth it for me.
