I was truly horrified to hear about this show. There's so much talk about parents should apply judgment when they post something about their children, like photos or videos on social media but this show just takes it to another level.
As far as I know these shows normally don't achieve a lot, the Biggest Loser show in the USA being a prime example of preference of entertainment over serious results (nypost.com/2015/01/18/contestant-reveals-the-brutal-secrets-of-the-biggest-loser/).
Channel4 are now showing children trying to do the same. I have serious doubts they are going to achieve anything positive except for singling out those children as the obese gluttons with no will power.
I am certain there are more serious approaches to the obesity epidemics which don't involve TV audience and if there aren't, shouldn't the government put more effort into creating them?
