Are there any real benefits to IF aside from weight loss and a bit of boosted metabolism or watever? Will it help me live longer and feel better into old age? Longevity is very important to me.
I have no need to lose weight but since going Paleo I find that I'm often not hungry at normal meal times. I typically force myself to eat anyway out of habit. Should I consider just missing meals or will I waste away? By some measures, I'm actually under weight (6'2" and under 140 lbs, male) and tend to have a really hard time gaining anything.
I can see why I don't get so hungry - my meals are usually higher calorie (lots of fat) and more nutritious in general (eating "real food") so maybe I just don't need as many meals.

ive heard people using things like calorie restriction to increase longevity, something about cells only being able to replicate a limited amount of times, so if you reduce the energy going to them they replicate at a slower rate... in theory increasing longevity.
might be worth reading if youre interested(spoiler:it will if youre a rat)
Blood glucose stabilization, increased insulin sensitivity, lower blood pressure, lower cholesterol (interpretations may vary), ketosis, some proponents will say heightened mental clarity, HGH elevation if coupled with heavy lifting, one thing I have noticed when I work out fasted is that I am clearly stronger; somehow I can just lift heavier and more reps it may be all mental, maybe a product of heightened mental clarity/focus?
Autophagy. It initiates an intracellular cleanup program that removes broken proteins from cells and also signals the immune system to go clean up virii and bacteria.
More generally, cancer cells can only feed on glucose, while normal cells can feed on glucose or ketones. So it's easy to imagine that whenever you fast and go into ketosis, you kill tumorous cells in your body (everyone has some in their body, but when they become too many, you get a cancer). But I don't think there have been studies demonstrating this.
