Don't get nervous! Sometimes the scale doesn't reflect what's going on in our bodies. Like gardenerjoy said, you can be losing inches even if the scale isn't showing the loss, because it's holding onto water. Who knows why the body holds onto water sometimes (some people think it's adjusting to the fat you're losing) but if you are staying OP and the scale isn't showing it (and it did before), you can bet water is the cause, and you will eventually have that whoosh! I don't know if you are weighing everyday or once a week, but I know if I weighed only once a week, I would have questioned a few times if anything was happening because of how water causes my weight to fluctuate. I say take your cheat day and enjoy it! Meanwhile, make sure you're drinking 64 oz of water a day and try not to worry about this. Two weeks is really not that long, although I know it feels that way when you're being so good!
