But what’s the role for self-discipline and putting down the ?

Everything is heritable, you know the drill. That includes self-discipline and calorie counting/intake control too.

But everything is heritable to varying degrees lols. Gotta be a little E in the mix too

The big cohort changes in obesity etc. mostly reflect environmental changes, and one could similarly change them again by taking actually effective action. But I don't think there's any small, easy and effective action one could take.

Some obvious ideas. Put a tax on food as a function of its caloric density (eat less dense food). Put a tax on restaurants as a function of the calorie count of the dish (promote smaller dish sizes). Put container size taxes/limits on food.

Use tax% for income tax purposes. Tax ingredients in products that tend to promote over-eating, say, sugar. Get everybody to switch to diet drinks whenever possible.

Not necessary in favor of any of these, I'm just saying the kind of actions one could take that might have some major impact, if one was so inclined. But I doubt there are any actions one can easily fiddle with.

How about starting simple to educate people how to read a nutrition label and understand that calories matter. For that matter, do something like requiring food producers to produce nutrition labels with 20 pt font or face fines
