Amen, and if a person goes in and out of sickness, I think that gives an advantage of perspective - like being one's own twin study. That's how it is for me.
I really, really hate to be in on the current ant-sugar trendiness... but I've been zeroing in on something very recently.
I've been varying heavy workouts (squats) together with whey (or soy isolate) consumption and sucrose consumption. With sucrose, I take iodine tablets to suppress candida GI effects (and that tactic works well). On some such days afterwards, I have to get up every hour at night (we need a polyuria smiley for comments like this), and sometimes I don't. General whole-body inflammation has to be present, e.g. from a virus cold. With that prime condition satisfied, it seems that maybe sugar = polyuria. The best antidote is two ibuprofens at bedtime.
I could easily refrain from sugar, but without PWO sugar I won't recover nearly as well and will be possibly plain tired for days. My current guess is that the extra surge of insulin which sucrose provides makes for powerful transport into the cells for whatever molecules are needed for recovery - including but not limited to the fuel that's also needed to eject waste products from each cell.
Satellite cells might very well be involved. (Muscle cells have many nuclei, plus there are spare nuclei [aka satellite cells] waiting alongside each myocyte for when they are needed to oversee all of the relevant post-exercise chemical processes.)
Quick ending: the sugar then also maybe-probably stirs up my joints, which get into a self-perpetuating cycle and that needs ibuprofen to disrupt the cycle - else it gets worse and worse by itself.
I have never had gout - but had a parent who took allopurinol for uric acid stones prevention.
That's all kind of disjointed but I'm posting it anyway in case somebody has some similar observations. I am tired of typing.
