It taught me that the deeper you delve the harder it is to draw a a proper conclusion on something because you need to go the next step to say why.
I don't like the whole of humanities nutrition advice based on small studies from untrained people do a leg extension. Anecdotally there is enough evidence for the 6 as opposed to 3 , 1 , 0 , 150. If something works you do it if not move on, it's really that simple... I have tried if I did t like it, I got weaker, wasn't happy so no point me doing it. I'll continue to eat my 6 1000kcal meals because it works for me.
