I weigh myself every day, now that I'm trying to lose weight. But it is confounding.
For example, this morning I weighed myself the usual way. (That's naked, after my morning workout, but just before I get in the shower.) On the first go, I weighed 161.2. I wanted to see the % body fat, bone mass, and other readings, so I weighed myself a second time. ...Same thing: 161.2.
I heard my husband's ring tone, so I scampered (still naked) to the phone. That took maybe a minute. On my way back towards the shower, I decided to urinate. Curious about how much less I'd weigh after urinating, I got on the (unmoved) scale again.
Keep in mind the elapsed time between weighings was less than five minutes. It should go without saying that I didn't eat or drink anything, and was still naked.
This time, the scale read 161.5. Baffled by the 0.3lb weight GAIN, I stepped off, then back on, again. Nope! I was still 161.5, now. I did this again and again. ...161.5 each time. (So, that's the weight I recorded in my food & activity journal.)
I don't know how this is even possible...physically. One might argue that my scale is unreliable, but that theory already led to me buying a fancy, new scale, after the old one gave me similar results.
This isn't the first time, though. On a more spectacular occasion, I weighed myself, then sat down at my computer, to check email. You know how that can go... Before I knew it, it was 2 hrs later. Nothing about me had changed. I hadn't had anything to eat or drink, and hadn't changed my clothes. Purely out of curiosity, I weighed myself again, and the scale indicated I was (inexplicably!!) 2 lbs heavier!
How can someone mass 2lbs, or even 0.3 lbs, more without adding anything? When I answer that question, maybe I'll finally see some results. (Despite eating under 1,500 calories a day...many days less than 1,000, and working out so hard every day, I'm always at a net gain of 1-5 lbs, compared to the day I started trying to lose weight. I do have POS, and the most common side effect is "inability to lose weight," due to the condition's effect on insulin sensitivity.)
