But using as little energy as possible and consuming as much of it as possible, all else equal, is LITERALLY the natural order. That’s our evolutionary programming. We rely on our big brains to achieve more complex instrumental goals.

OP’s reasoning is sound, because it suggests that certain choices are made out of ignorance and are therefore not rational (i.e., “not natural”).

Ultimately, more information leads to MORE diet and exercise, whereas more information leads to LESS “trad” lifestyle.
