Honestly, I don’t mean to disappoint you but I don’t think they should do lapband surgeries any more. I had mine done 11 years ago. I lost about thirty pounds, my body adjusted to the lower calorie in take and I stopped losing. I was throwing up most of my meals because food kept getting stuck so how I managed to regain the weight is beyond me. Today I am exactly the same weight I was when I had my surgery. My diet during this time has been (on and off) low carb, (only thing that came close to working for me), combined with walking and kayaking. For awhile I had worked up to walking ten miles a day two times a week. That’s a four hour walk, two times a week. With two or three days of 1-2 hour walks. I was putting in the effort, tracking meals, carbs, calories, etc. just to maintain my weight. As soon as I let up, the pounds came on.
If you have time left before surgery, research lapband success rate. I would strongly suggest a different type of surgery.
