Should Obese Children be put into care?

The obese children ive encountered have nearly always had obese parents. The parents have terrible food habits which they pass down onto their children.
I dont think the children should be placed in care but they should be assigned a social worker, the parents should be sent on food/healthy eating courses which should include lessons on appropriate food portion sizes and mental health classes to help with any eating disorders/bad eating habits that the parents have difficulty controlling.
It should be mandatory for parents to have their child see a doctor once a month to monitor their health, if they dont comply a social worker intervenes.

I had an obese friend in school and her mother made her lunches, the size and quantity of her lunch was more than a healthy person would eat in an entire day, she would also have money for soup, rolls, crisps and sweets in the school canteen.
She has two kids now and theyre both obese.
