WTF!?

I went UP half a effing pound!! What the hell is up with that?! I did everything right. I mean everything. Not in a Kyla (reference LYLASandCo.) I-did-everything-right sort of way. I know how to do diet, I know what's good and bad, what counts what doesnt...and I still went up!! I swear to God this is why fat people kill!
