Welcome Bobby!
When I restarted keto in early May, it was my third time on it, this is the first time it feels like a “forever” thing (a true lifestyle change). I have had the experience also that the weight didn’t melt off for quite as long this time around. I’m not entirely sure why, but each of the two times I came back to it (with a break of several months in between), the weight loss slowed way down earlier than the previous time. That said, although the weight has been coming off in fits and starts, it’s still continuing. I have gained a little weight some weeks but overall the trend is still downward so I just KCKO. I think our metabolic starting points are just different from when we did keto before.
I think as far as how long any stall goes on for (not just PISS but stalls that can happen farther down the road) seems to be highly individual, not only based on what you’re eating but on things like stress, menstrual cycles (if you’re female) and many various other factors. So it’s impossible to predict.
