I've lost over 10lbs since my initial weigh in, unfortunately, my insurance goes by your weight at the end of your supervised 6 month diet! Luckily, I will still have a bmi over 35 with several co-morbidities by the time of my pre-op appt. 7/2. I had to check into that, I was worried and thought I may have to scale back on the weight loss until after my surgery.
