What do you think should be done about the obesity problem in America?

I’m starting to feel like some sort of political action should be taken to combat the obesity epidemic in my country.
I saw over the course of a work day at a pharmacy many obese adults and even clearly obese children under age ten.
I went into Walmart and saw a family of three all using a walker or mobility scouter because of their tremendous weight.
I’m starting to question if there should be some government action to combat obesity like we combat Covid.
Maybe higher taxes for fast food and tax deductions for using a gym.
