Bummer about the scale, Mandy. When the weigh-ins don't go as planned, I really want there to be an obvious answer, like I ate pizza or got 2nds of potatoes, but sometimes, we are just at the whimsy of our stupid bodies... which we have spent anywhere from a few years to a few decades training by eating poorly.
One thing I've come to realize is that for me it's just not as easy as counting calories... at least not for losing weight in the short term. I watch what I eat, how much I eat, when I eat, and in what combination I eat foods. For me, protein is fine... unless I eat it later in the day or eat too much; slightly higher sodium meals can be OK, IF they're early enough in the day that I can drink enough water to balance everything out with loads of water; some simple carbs (or higher glycemic index foods) are fine IF I'm about to do something strenuous that'll burn up the calories quickly.
I don't know, maybe I'm full of it... but this is the thinking I use day to day.
Hang in there, Mandy. You're doing great!
