H.M.
I agree with the others don't weigh every day and when you weigh you want to have the same amount of cloths on if at all possible. When I used to weigh myself I would do it after I got out of the shower. But as close to the same time. Also the change could be if you are fixing to start and bloated. There are a lot of reasons for that. I personaly don't weigh myself anymore if I can keep from it usually only at Dr.s apt. And not it's not because I don't need to loose weight cause I do. Me and my scale had a falling out (or should I say falling off) and I broke me wrist so I kicked it out of the bathroom and my husband or kids hid it. :O)
