alt Hacker News> Do you have an actually reasonable set of laws that could solve these societal level problems that encourage obesity in let's say, the next ten years?
Sure, Canada banned trans fat.
There is absolutely no reason they couldn't ban drinks that contain more than x% sugar, or portion sizes that are bigger than y calories.

Excellent example!
Internal Combustion Engines will be illegal in new vehicles from 2030 in many jurisdictions around the world (2035 in others). Yes, it's coming!
Tire and brake particulate is actually a big component of pollution and EVs will cause more pollution from tire and brake debris, which is already a larger portion of pollution than tail pipe emitions. We're increasing one type of pollution and decreasing another type, we'll see if long term it's a net benefit.
Also, they could ban those things in places like SF or more liberal places, however I believe those are politically losing policies and wouldn't pass in places that are actually experiencing obesity.
