> Very difficult to create isolation environment

If you eat at home, it's actually pretty easy: Just go to the supermarket with a full belly. It's amazing how disciplined one can be in their groceries shopping when they shop with a full stomach.

When, eventually, your fridge and pantry aren't stocked with sugary junk, it's a change of environment! After that, it's pretty much out of sight, out of mind. The ocassional indulgence at a social event is not the end of the world.

The real problem is that many city people don't really plan their groceries, but just open doordash/flink/gorillas/whatever when they are already hungry and tired. No good choices are going to come from that habit.
