Good job, Dread. I think it usually takes a lot of repetitions of fasts of certain lengths, i.e. OMAD, alternate day OMAD, and longer fasts, for the individual to figure out what is happening to them, as far as weight (if there are different results with the different fasts). If it was all charted, with the many repetitions and cycles, then perhaps there’d be patterns in the data. Even then, differences in what food was eaten and possibly in electrolytic balances could hide or alter patterns - a pound or two here and there and things will be skewed.
I agree that mixing things up is advisable, overall, and hey - your long term trend is really good. If your weight is staying in a close range overall, and you’re working out (and especially if HGH is being stimulated by the fasting) then sounds like the stage is set for that increase in lean mass and decrease in body fat.
