Ditto. Marniadec took the words out of my mouth.

i used to daily but now only once or twice a week. my losses have slowed down as i've become closer to my goal weight.

Yes, definitely! I think that is one reason why not being consistent of when and under what conditions we can weigh ourselves can make us batty. When I was first trying to figure out how often to weigh myself I used to do it several times a day. The results were very varied based on if I was wearing clothes and how heavy they were, how much I had already eaten or drunk that day, whether or not I had had a bowel movement (I hope that wasn't too much TMI), if I had exercised, etc.. I think that weighing in the morning helps because your body has had some time to settle from the day before. In fact if I forget to weigh myself in the morning before I eat I don't weigh myself at all that day. I know it won't be an accurate comparison to my weight the day before.

I did find though that doing experiments with weighing myself more often gave me enough perspective to be comfortable with weight fluctuations from day to day or hour to hour.

I officially weigh in once per week, but like to hop on daily, mainly so I know what to expect on Sunday. The numbers are pretty up and down but I can usually tell if they are going in a downward trend and I am able to not take daily numbers too seriously. I have considered weighing daily and averaging the weekly number (to compare it to the previous week's average and measure pounds lost), but so far I do not see a need since I have liked my Sunday readings, haha

I weigh myself every Monday, unless it's the beginning of a new month, which I weigh myself then just so I have an accurate weight loss per month as well as per week.
