I was just stating my own experience without exposing too much personal history. For me, mild intermittent fasting led to deep intermittent fasting, multi day fasting, then week, then half a month. At that point it was anorexia not fasting.

I meant no disrespect to him at all nor the implication he was suggesting it - just wanted to throw a caution out. For some, it could lead to unhealthy excess.
