I'm not in any group, to be honest I like fats peri workout because the energy spike i get is more stable and lasts longer. I do know how to work with insulin sensitivity/nutrition timing.
I didn't throw my opinion out there though because it would complicate things. Saying you couldn't get past 180lbs without implementing things like this is a very individualized statement.
Obviously worrying about these things didn't halt your progress (great job by the way), but for 95% of newbies it would.
