If the parents have had all the advice, counselling etc. and still do nothing to help their obese children get their weight under control, then I do think that these children should be taken away from the parents. We would not object to them being taken away if they were dangerously malnourished and this is no different really. Both present a risk to the child's life! This will only work though if the children are then given the right support, both physical and emotional, to help them back to a healthy weight and to understanding where their parents went wrong. However, where the parents have done everything in their power to get their child's weight down, the child should not be taken away, but offered a place in a fat camp with nutritionists and fitness experts who help. Their GP should be able to prescribe this. This way, if the parents of the child refuse to let the child go to the camp, perhaps the GP could threaten to refuse any other treatment , as a way of pressuring the parents. Either way, repairing the child's health / life has to be the main focus.
