Yep, like everyone has said, it's definitely a thing. I'm about 7 weeks post op, surgery was 4/15, and for the last 2-3 weeks, I experienced zero weight loss. I'd been following my diet religiously, exercising etc. About 3 days ago the scale finally moved, but instead of seeing a 3-4lb difference like I was in the beginning, I'm only dropping one pound at a time. But, this is fine with me, as long as things are moving! Trust me, I know it's disheartening, and you're wondering how it could be physically possible to not lose weight while eating so little. You may think you're "doing it wrong" or the surgery didn't work (lol), but in actuality, your body is finally done purging the glycogen and water stores and is now using fat for energy. After your body makes that adjustment, the weight loss will continue.
