First day weighing myself, I was 307lbs today from 330lbs. Thats liquid diet and 2 1/2 days post op. Is that the normal average for loss during this period?

Hi Kyle, I think it's normal. The support groups that I have gone to so far have had quite a few people who have lost over 20 pounds within the first two weeks. If you feel uncomfortable with that you can also ask your doctor.
