How can you lose 3 lbs. overnight? The scale doesn't move all week long and then BAM one morning it's down 3 lbs. Is this real weight loss or just more fluid? I feel a little thinner but I don't really understand it.

I also just noticed that I had my current weight wrong on my profile. It was 10 lbs. wrong! I need glasses! 5, 6 they kinda look the same! The weight loss in the same but the wrong number looked much better!
I've adjusted it now to reflect the real me!

You had a visit from the whoosh fairy.

Happens to me so often and it is happily shocking. I think it's like our bodies suddenly let go of water weight, or something.

i'd like to hear the real science behind it, though.
