Fat kids? Try less palatable food.
I've seen too much media hype concerning fat children. Parents moaning on talk shows about how they just can't control their 125 pound 3-year-old. We have four children and I found something that works really well while they are still young enough for you to control what they eat: Give them food that really doesn't taste very good. I don't mean put wet garbage on their plate. I mean give them small portions of foods that they don't care for (beets, spinach, green beans, whatever) along side of small portions of food that they normally would eat. Don't let them have seconds until they finish what's on their plate. Works great. No more fat kids. Voila!
