Well that just took me a good half hour or so to read everything from page 1 to now, but I'm caught up! Very interesting thread and you haven't even started yet
lol. I am really intrigued about this, because I just finished a bulk of my own and am starting my cut this Monday - still trying to hammer out the details on what products I'm going to bring into play a little ways in, though (what I'm doing is going supplement free aside from staples for the first couple weeks with just slightly lowered cals; adding in cardio slowly and then tapering cals/adding more cardio as necessary when progress seems to stall - and
then bringing help into play to just blast through the rest of the cut).
Your thread has been a very big learning experience for me because I've been natural, but have toyed around with the idea of changing that on this cut. I've researched all of this stuff for a long time now just to understand how each thing works. We'll see what I decide...
Just a little advice on keto, since it's what I ran in my last cut: I would personally look at carb cycling for a little while initially. I'd front-load my carbs and gradually taper all of them down (i.e. if high carb day used to be 400g, bring it down to 300 next week and make your moderate and low days reflect the percentage shifts as well, etc.). Then, I'd jump into the keto diet once even your high carb days were lower range (your body should like this a little bit more and it should help keep fat-burning high). At that point, once you're starting keto, I like to stay at as low of carbs as possible (not even fruit) and every 3rd or 4th day do a carb-refeed meal (usually @ ~150-200g of carbs - just carbs, though, keep protein and fat to an absolute minimum at this meal and use it as your final feeding a few hours before bed). Pre-load a nutrient partitioner to that carb meal to ensure it's all being sent to muscle as well. For the initial start of keto, you may want to go 5 days before hitting the refeed - your body will tell you what you need.
I will be very closely following this thing, man. Really tempted to cross over into the land of no-longer-natural
cause page 1 was so long I got bored
