       I rarely used to weigh myself, but I recently started doing so daily, and I was surprised by how much the results fluctuated.In this study:https://pmc.ncbi.nlm.nih.gov/articles/PMC7192384/they found:“Within-week fluctuations of 0.35% were observed, characterised by weekend weight gain and weekday reduction which differed between all groups.”But I seem to have peak-to-peak fluctuations closer to 4%, or ten times as much as the 0.35% seen in that study!My food intake and exercise patterns are pretty constant, apart from doing a longish run every Sunday.I’m curious as to what kind of fluctuations other people have measured on this timescale — especially when they’re not knowingly changing any of the relevant factors.

       @gregeganSF Could it be the scale is imprecise?I haven't had the patience to weigh myself as regularly, so I don't have such data. But when I was at my minimum adult weight (slightly underweight) it felt like the weight was super constant, I saw the same number every time. Now that I'm exercising more, have built up some  muscle and am eating more, it does change between when I'm stepping on a scale.

       @kibrika @gregeganSF I used to be underweight too, and back then my weight was super stable. But now that my weight is much healthier, I'd say the fluctuations can be as high as ±1.5% (so 3% difference between lowest and highest) over the course of a week (and ±5% (10% difference between lowest and highest) over the course of a year). No exercising, just HRT.
