Yeah, I'm aware :) I think people that are healthy can try it for themselves in small steps (with supervision of a doctor, if possible), and see how it makes them feel. I have been objectively tracking my mood (Remente), sleep (Ouraring), strength (only body weight exercise, tracking reps, cadence and more). Overall it's been improving in all categories, from very good to even better. If it's a result of the fasting or something else I've changed is hard to tell, but I'm pretty sure fasting is not making it worse for me at least.
