I'm doing a paper on Childhood obesity. Any Ideas?

Do you have any ideas on how econimic incentives and government actions might help to address the problem of childhood obesity?

I only can think of highering taxes on junk food.

I need more ideas.

Thanks! =)

high tarrifs on junk foods,
tax rebates for sports fees (club fees and sporting equipment)
a sliding scale of health care subsidies, where by the unhealthier you are and more overweight you are, the less subsidiesed your medical support is.
enforced fat camps, where by children without a medical exception exceeding a certain body mass index would be considered abused, and as such would allow government to remove the child from that environment and place them into an intensive weight loss and education program untill their weight becomes acceptable (this also puts an onus back on to parents to ensure their children dont become overweight in the first place).

these are a few ideas, and some may be considered extreme, but wehn you consider that 90% of obesity stems from inactive lifestyle and poor dietary choices, there really is no excuse. i do however feel for those that have a genuine medical condition that makes them overweight, but they are a small minority

send fat people to iraq.
explain why diet and excercise is so impportant and if ur reading to a class or something scare them with statistics
more sports,
more education on the effects of obesity after childhood
maybe start with the parents who are feeding their children this stuff, give them fines for children who are morbidly obese
sort of like child endangerment, there has to be a law that it would fall under,
Notice how in movies,the fat kid always the funny one.
Public schools are so concerned about the floor in the gym's getting scuffed, that they will only let kids play if they have on certain shoes. Otherwise, the student has to sit out and watch....way to encourage exercise!
Right now parents get an extra $1000 (IRS) tax credit for children under 16. Take it away if the children are obese even overweight.
