My scale goes up and down a lot. I check my food diary for up days and those are generally the high sodium days or days where I drank less water. I just look at my calories, if I'm in my range or barely over, I know I can't have gained that in lbs because it scientifically doesn't work that way. If I've eaten a surplus of 500 calories a day and gained weight... I'd believe it was more than sodium. XD
I've decided to leave 3FC, In the crowd of so many, those of us with no success that have the audacity to feel bad about our incredibly slow and almost stagnate weight loss, are merely a nuisance to those that are successful. I hope everyone else finds the support they need.
