I think the phenomenon is poorly understood and studied, but it's likely not the calorie restriction itself, like you claim. Apparently it has to do with autophagy (https://en.wikipedia.org/wiki/Autophagy), which your body seems to enter when you restrict calories. IF apparently stimulates your body to perform autophagy due to the fact that you're timing your meals. TBH, I still need to do my own research to see how much of this is real vs. pseudoscience, but I've noticed an improvement to my health. Whether that's placebo effect or not, remains to be seen. |

As for IF, as you say, it is basically not proven to do anything (no 'phenomenon' at all). Simplest and most logical reason for success is because it helps people stick to their diet, by arbitrarily restricting the window of eating.
Opinion I read on r/leangains is that some people find it easier to e.g. just eat two 600-800 calorie meals within their IF window, rather than sticking to a diet that involves 3-4 smaller ~300-400 calorie meals, spread out through the day, none of which feel 'satisfying'.
