Teach families with severely overweight children on how to live healthy instead of putting them in foster care

There have been cases where severely obese children have been taken from there families and placed in foster care, by the government, in hopes of losing weight. Once the child has lost weight they would eventually return to their family, but I feel that children should not be forced to leave the parents just because of their weight. So I think the best solution would be to have the family be educated on how to eat and live a healthy lifestyle. By taking a government class taught by nutritionists and trainers.
