The other, obvious, solution is to stop schools from selling "junk" food. School is there to educate and nutrition is of fundamental important. Children need guidance - if you offer them burger and chips or salad OF COURSE they will eat the burger and chips. The choice needs to be taken away.

God is our guide! from field, from wave, From plough, from anvil, and from loom; We come, our country's rights to save, And speak a tyrant faction's doom: We raise the watch-word liberty; We will, we will,we will be free!
