I don't know too many people who do full-blown hardcore CR, it is very
difficult for most people to combine that with being fully productive in a
Western working environment (including overtime etc.).

Hmm, though we probably do better than the Western average, >80% of us
probably *are* slightly overweight (with 88 kg at 178 cm I'm ~10 kg away
from my optimal (whatever that is) weight). So, a somewhat reduced caloric
intake can be supplemented with mild exercise with beneficial results.
Given that we're not designed for a fully sedentary lifestyle, any extra
movement you can get puts you years ahead of the average mouse pusher.
