The only basis for compelling medical treatment against a parent’s wishes are if a child is at imminent risk of death — meaning days or hours — and a proven cure exists for what threatens to kill them. Obesity does not pass these requirements.
The risk of death from obesity is real, but it is way down the road for kids. There is no proven cure for obesity.
But if we don't yank heavy kids from their obesity-encouraging homes, what should we do? [snip]
... might we try to change our food culture? This means doing what we have done for smoking. Demonize the companies that sell and market food that is not nutritious. That means you, candy, soda, fried food and snack food outfits. Tax them too. And get Hollywood and television to make overeating and not exercising uncool just like they did with smoking. Put exercise back on the menu for all school kids.
So which is it? There’s no proven cure for obesity or changing our food culture will cure obesity?
