Getting over the humps at round weights 16st, 15st etc...

I didn't experience that, actually. Apparently some others besides you do, though.

I see that you weigh in stones. Maybe consider weighing in pounds or kilos and see where you stall that way? (<=== I'm joking! ).

More seriously: Do you use a weight trending app? This might help with the psychological side of this, i.e., make it less stressful.

Those apps are not a magic crystal ball, but they use extra-fancy statistical averaging methods to make a mathematical guess about one's weight loss trend. (They kind of dampen down the effect of random day to day water/waste fluctuations.) Some people find that helpful.

There is Happy Scale for Apple/iOS, Libra for Android, Trendweight (which requires a free Fitbit account but you don't need a device, Weightgrapher on the web, and probably lots of others. Many of them are free.

I use Libra. It was especially helpful during loss, but as also helped during the years of maintenance since. In rare cases, even the trend line in the app can be misleading, but it's usually helpful compared to just looking at a graph of scale weights that tend to fluctuate up and down randomly, even when the overall longer-term trend is down. (Daily weights during loss can look like small peaks and valleys on a downhill mountain slope, during loss.)

Another consideration: Some scales have a hidden memory. Usually it's not a long term thing, but is designed in to keep people from freaking out about normal measurement variability in these only semi-precise home devices.

Without scale memory, if someone is right on the cusp of some particular weight boundary, they could step on the scale one moment and be (say) 132.5 pounds, and step on moments later and be 132.7 pounds or 132.3 pounds. That can rattle people. Therefore, some electronic scales will give the same reading for a bit if whatever hits the scale next is close to the previous reading. Usually it's only a few minutes. I've seen some people here say that theirs can be longer, though.

What a person can do who suspects that is weigh themselves, then take something heavy (dumbbell, stack of books, kettle of water, whatever) and get on the scale again to get it to reset, then repeat the weigh-in without the heavy thing.

Though the initial comment about weight types truly was a joke, I wonder if people who weigh in pounds might be more likely to experience "stickiness" of scale weight at the 10-pound intervals rather than the 14-pound intervals that would equate to a stone, for example. If the scale designs have something to do with the situation, the weight type being used might be a factor. We pound-people might not even notice if we stuck at 14-pound intervals, though. 🤷

Best wishes!
