The cure is to teach from an early age about impulse control, moderation, and how to spot signs of addiction in yourself early. This goes for:
Social media
Drugs and alcohol
Food
Or literally any other addiction. I don't think this is a useless thing to discuss.
The presently addicted and obese thank you for your service to the future.
Ok, in the US start talking about food addiction seriously and see what happens.
Do you remember how long it took to get tobacco mostly banned in the US? Do you remember how much the tobacco industry played the skeptic and introduced bunk science into the mix?
Well Coca Cola, Pepsico, Nestle, and all the other junk food companies have been on this game for years now. Want to change school curriculum?, well your political opponent has $100,000-$1,000,000 more than you from the make people fat industry. Meanwhile there are a crazy number of attack ads against you for being a crazy commie that wants to control peoples lives, you socialist bastard, you're against freedom.
And yet most obese people are no more addicted to food than you are addicted to oxygen...
It's so bizarre how many people will pretzel their way into moralistic non sense to find a solution to what is clearly a medical problem.
Obesity as far as we understanding it now is an hunger regulation problem. For unknown reason a lot of people still feel the need to eat even when their body is clearly in calory surplus.
No amount of of impulse control or moderation can make you override billions of years of evolution and not eat when you are starving... if we could... society would be a very different place
