Tell me why no one is willing to tell parents that it's their fault their kids are fat?

I just don't get it! I'm researching information on Childhood Obesity with the goal of how to prevent it. There's TONS of information out there (no pun intended), and yet everyone tip toes around (or completely IGNORES) the fact that parents are to blame for the majority of obese children in America!

Like it or not (and yes, I AM a parent), it's NOT the media, McDonalds, fast food advertising, the school gym program, Television, video games, or a slow metabolism that's making your children fat. It's a parents inability to say "NO". That's right! You're the one who has control of the TV, the computer, what food comes into your home, whether your kids are active, and whether they eat at fast food restaurants. YOU, as a parent, are the one who sets the example! So take a look at yourself...are you setting the example that will keep your children healthy and fit?

Tell me why...
