I've been logging daily weights since early February, and the weirdest change isn't appetite—it's temperature. My hands go icy around 3 p.m. even with the office heat at 72. I've started keeping fingerless gloves by the kettle and a throw on the couch.
The scale is doing its usual pinball: down 0.4, up 0.2, flat, flat. My weekly average is still drifting down about half a pound, so I'm calling that the signal and leaving the rest as noise. The cold is annoying, not scary for me, but it's real enough that I notice it before hunger.
Is this showing up for you too? I'm treating it like any other data point: log it, layer up, don't let one weird afternoon write the whole story.
