I got my band on 12/22 and as of today I'm down six pounds since surgery. I started my pre-op diet in July and I'm down thirty-five pounds total since then.
Honestly, I've read such a wide variety of weight loss responses on here that I'm not too worried about it (I wasn't going to weigh at all, but my doctor told me he wanted me to weigh every morning). It seems that some people come out of the hospital with extra weight from fluids while others come out weighing less. My doctor told me to shoot for 1,000 calories a day with 50 grams of Protein, plus 45 minutes of exercise a day with a heart rate of 120. I figure as long as I'm following what he says, I'm happy. I'm not as concerned with how fast the weight comes off, but that it comes off and stays off.
Don't sweat it, follow what your doc says, and call him if you have any questions.
