Do other people find their weight can vary by quite a few pounds day to day? This morning I weighed myself and was 3lb heavier than yesterday. I certainly didn't eat 12000 calories yesterday (more like 1500), I weighed myself at the same time (first thing after a wee and before eating/drinking anything) and yet this huge difference....what's the cause?
(I know you're not supposed to weigh yourself every day and presumably this is why.)
