I musta weighed myself when I was dehydrated

That happened to me two weeks ago...only it was almost four pounds...I about puked.  And worse yet those four pounds were dang hard to get off again.  My nutritionist happened to call me during that time and she said it happens.  Sometimes our bodies just have to reset themselves.  We went over what I was eating and she said to keep doing what I knew was right and I did and ounce by ounce that weight came off...and then suddenly I dropped 2 pounds and then three pounds...so I think it has to do with our body being in starvation mode and saying enough is enough and just needing a rest.  Good Luck and just keep on keeping on.
