Weighed myself on own electronic scales before my 1st ww weigh in last Wed evening and there was half a lb in the difference, ww weighing me the xtra. Just had a sneaky wi on own scales and was actually up a lb. How the hell has this happened?? Ate my daily pp and zero weekly pp, have walked 4 or 5 times, not due totm and had same clothes on as last week wi. Not impressed to say the least. Anyone know what might be going on?
