We watched Supersize Kids with our kids (10 & 11). Even the shocking bits. The Dad was ever so right - surgery is not the answer.
I agree with Jon. IMHO, it is up to parents to take full and total responsibility of their children. How can it possibly be anything else?
Hence I lost about 6st because my weight was "affecting" my daughter. A few years back she was in similar stages to that 6 year old. As a family we're a lot more "healthier" due to changes in attitudes/lifestyle (namely me and wife).
Not sure if this was mentioned but it seemed to me that some of the kids were comfort eating - family turmoil, school bullying and low self-esteem are devasting on those young minds. I hope the overweight 13yr old does well as he views his fitness instructor as a "kind big brother" which will boost his moral. His aunts, who did care, where misguided for berating him so much.
I felt the 22yr old who underwent surgery was incredibly brave for "baring all" on natioanl telly. What a remarkable example to us all.
The whole moment was spoilt when my 10yr old son quipped in that he'd lend me some money to get rid of my slightly baggy skin.....!
