I keep seeing this on HackerNews - everyone seems to convinced that keto, intermittent fasting, and fasting are the new holy grail, I am unconvinced. I am convinced in the good old "enough sleep and cardio" theory though, since both have known working mechanisms (incread blood flow and debris clean up during sleep).

why are you unconvinced about fasting? have you tried researching and reading the scientific articles about fasting and the other topics.

If you're thinking in terms of "holy grail," you may be subjecting yourself to an "all or nothing" fallacy.

Generally, we're discovering how to lead our bodies through the healthy operating conditions which kept our ancestors alive as we navigate a modern world of high-tech capabilities, treatments and availability crossed with widespread lack of discipline and healthy habits.

Are there any studies on positive effects of fasting which control for caloric restriction / weight loss?

I don't know if you are purely talking about mental health. But I would add in some resistance training, for bone health amongst other things.

Go read some of Dr. Jason Fung's articles on his blog. Not saying fasting is a panacea, but doing it regularly unlocks lots of different health benefits. https://idmprogram.com/blog/

Sleep, and a mix of cardio and strength training would most closely replicate how our bodies evolved. Pre-civilization, humans would have needed both strength and endurance to make shelters and hunt. Both running, and lifting/moving heavy things would have been common.
