I take the stance that health fasting is vastly different in effects from fasting as a religious observance. For instance the frequency and duration of so called "Health fasting" among other factors including the fact that "health fasting" seems to self select for people already at risk of disordered eating.
Yeah I think I agree with that. I'm skeptical of fasting outside of a specific tradition and guidance. But don't like to see the value of those traditions dismissed either.
