> Last time on the fat fasts, my workouts absolutely tanked. I went down 50% in several lifts, and, a few times, I nearly blacked out (!) while exercising, feeling my vision shrink.
This I recognise from my athletic youth. During long races, say twenty minutes or more, if I really overdid it, my vision would dim and the peripheral vision would go. It didn't even help speed-wise, because my technique would fall apart at the same time.
I once described this to a proper rower, the sort that competes against other countries, and he said "That's nothing! Every time I do an ergo I go blind!".
Probably what's happening here is that you're getting low on glycogen. If you're not eating carbs and you haven't got enough protein to do gluconeogenesis, you can probably run out of short-term fuel very quickly with not much effort.
> I think for now the most reasonable assumption is that the first fat fast was an exception, and, in general, lowering protein much further than ex150 doesn’t help at all, and the monotony (or lack of protein) of the fat fasts leads to behavioral issues.
This sounds right, we need a certain amount of protein for maintenance.
I imagine that what's going on with the (protein restriction fixes appetite idea) has something to do with burning excess protein for fuel, sticking it into the energy cycle and interfering with something. That's going to happen if protein intake is above the required amount.
But reduce protein intake below that essential level and you'll get actual protein deficiency, which I'd imagine involves cravings and metabolising your own muscles as an emergency measure.
One can cover a multitude of fuckarounditis by putting on a white lab coat with a nametag that reads "scientist". For instance, even though I soldiered on through a 6-day plateau on potatoes (inspired by your last long plateau), by the end I'd already decided to do an experiment. I'm on day three of attempting to stimulate FGF21 production in the morning by consuming 500 calories of pure sugar before fasting all afternoon (and then eating potatoes for dinner). Might be a total failure in terms of weight-loss, but it's an interesting experiment. Of course, if it is a success, I have no way to disambiguate the fgf21 effects from replacing 500 calories of my regular food with something zero protein. During the plateau I became concerned I was experiencing down-regulatin of metabolism, and this is an attempt in the opposite direction. We shall see.
idea is to simulate a 5 day fast without truly fasting. average daily calories 1000. but extremely well done to reduce hunger.
those are serious academics, not hucksters.
details are long. but I credit doing this twice + adapting style into my habits to a big eating improvement journey.
I was never fat. rather 5+ kg above optimal. still found it hard to go long without food. doing this kinda helped change eating dynamics. and "fasting" 5 days with their packages was surprisingly easy

Good luck!

have a look at FMD. fast mimicking diet.

I find it amusing that you crave tomato and alfredo sauces so intensely.
