Kids are so fat because too many parents (not all...I know there are some wonderful parents on this site!!) :
a) give them food to go away or behave. "be good, you get a cookie"
b) don't shoo their kids outside when it's nice. My mom was forever pushing me out the door to go play.
c) let their kids sit in front of the tv with a giant bowl of popcorn every night. for hours.
d) are in a hurry and give them "fast food" for lunch and snacks and breakfast and dinner.......remember when a tv dinner was a special event?
e) don't set limits on video game, internet, tv time. Kids should move....they are not meant to be sedentary.
But these are my opinions based on how my parents raised me.
I guess what I am saying is that so many parents are afraid of their kids and refuse to do anything that might upset them. Like actually parent. For example, my husband and I are looking for a dog and I contacted a breeder the other day. I told her we would be having children about a year after we got the dog and would there be problems. She launched into a spiel about how many times she sees parents come to look at her dogs with kids and the kids are running and acting up, messing with the dogs. And the parents seem oblivious to it. She said she won't sell them a dog because if they can't handle their kids, they surely can't train a dog. The point is that if a dog breeder brings it up, it must be a pretty prevalent issue in this country.
