This seems like the kind of article we like to discuss around here…

It’s been shown to aid in healing cancers if within a keto diet. I’d buy it.

Interesting stuff. Makes sense that we would get less unwanted growth (cancer, body fat etc) and induce less metabolic stress if we aren’t always trying to burn off excess energy to maintain weight. Calorie restriction without malnutrition seems to be the one reliable thing that extends life (it’s just not easy to do).

There has been some varying thought about weight and how differing weights seem to matter as a person ages.
While it’s not generally good for a person to be way overweight, being underweight does not always play out so well in the elderly.
That’s not exactly the topic but sort of a side thought that seemed relevant at the time…

A waist to height ratio of about 0.5 for men and 0.46 seems optimal. Though many find that they need to go lower than this to optimise blood sugar levels.

And that is one thing that makes me wonder whether it’s about the calories at all. ?? (Kinda like the firemen always seem to be at fires thing.)

The tradeoff to calorie restriction which almost certainly increases longevity in a vacuum due to lower BMR and less stress created by metabolizing food, is the decrease on longevity by making you weaker. It reminds me of animal longevity studies in that what works in a lab would not necessarily work in the real world.

I think that’s the whole basis for Fasting, right? That it started in earnest with a study on lab animals, and that starving them pretty much made them live longer?
I want to do some fasting just for the autophagy benefits, but I’m too addicted to coffee with HWC to really do it. I eat OMAD, but I’m pretty sure the 1.5 tbs of HWC I put in my coffee is breaking any sort of fast when I consume it.

My theory is that starvation doesn’t make me live longer—it just makes it feel longer!

I suspect this might be the big ticket item here. In a recent podcast, Dr. Patrick’s guest discussed how every time you eat, no matter what it is, you increase stress on the body, in some cases (such as leaky gut) doing more “harm” than at other times but, you are always entering a time of stress postprandial.
I think this leads to a requirement to carefully balance intake with fasting (I’m a big supporter of fasting for health) and, I suspect that living on as few calories as possible may be the smartest thing we can do (not that I do that… I’m human… I have my weaknesses).
I think that eating every other day or IF etc. may be some of the most powerful things we can do for health and longevity, I’m going to keep following the science with interest to see where it leads us.
Cheers,

I think that depends on how long it’s been since your last meal, how long it is until your next meal, how active you are etc. etc. etc.
Technically, anything with protein or that which requires the liver to “work” stops autophagy (according to Fung) BUT, if you are using longer windows before and after the coffee (even black coffee breaks a fast for autophagy) then, IMHO, it’s “worth it”, at least I know I’m ok with the trade-off.
