all bickering aside, does it really matter where the obesity comes from? I think the issue is that people just don't know where to get the help.
If the obesity is thyroid based, they need an MD, and then specialists. No gym work is going to cure it.
If it is overeating and lack of activity, a gym is needed, along with the proper support system. No fatass is going to walk into the gym and say "I think I've gotten a little heavy. Help me shed these 250 lbs.". They need a support system that can keep them motivated.
Further, if it's overeating and lack of activity due to the environment (like the obese kids), the parents have to do two things:
1.) Become educated on diet and exercise
2.) CARE.
I swear, sometimes it's child abuse.
