Is Intermittent Fasting Good for Longevity?

i tend to have like five or six things i tell people, like fr longevity, that are the big leapers. The first one is, forgive my french, but don't eat like an ass holehas the first one, exercise regularly vigorously. A limit alcohol, drugs, all that kind of stuff. Consiten, don't don't smoke. Limit your stress and try to sleep enough. It sike, ok, maybe intermittent fasting is this lever you can pull that gives you some a benefits, but, ok, well, here's possibly the downsid right?
