I'm gonna be blunt. I've lost 55 pounds, and I swear I'm bigger in "The Good Place" than I was ever, even in college. We are talking multiple inches. I'm an exhibitionist so the temptation to share the before and afters with you must be resisted, but suffice to say, after the joy of looking down and seeing it again . . . the second joy of the reactions. . . well . . .let's just say my username isn't a dream anymore, it's real.
I wouldn't be too concerned right now. Your body is still recovering from the surgery. Just keep eating like you are supposed to and make sure you are getting your Water in.
