1) Is it true you are on a liquid diet for 2 weeks prior to surgery?
I was on Optifast for 30 days prior to my surgery. It was not nearly as bad as I expected. They say the pre-op diets are to help make your liver smaller and easier to work with during the surgery. Also, the more lose prior to surgery, the less you have to lose later :-) I lost 16 lbs pre-op.
2) I am private pay so this is a huge investment. I am concerned about cravings, etc for 'forbidden' foods after the surgery. Is this an issue for everyone or does the nausea curb your cravings?
I was just banded a week ago. So far no major cravings. I think the pre-op diet helped that a lot. Also, the Dr helps guide you on the right foods to eat. Low carbs help to keep those cravings down somewhat, but I'm sure we will still need to make good choices and not give into all of the cravings.
3) I am getting conflicting reports that say avg weight loss is only 30-50% of excess weight. From your experience is that true? My Dr's office claims 60-75% of excess weight is lost. I started out weighing 229 lbs and told my doc that my goal is to weigh 150 (BMI charts list me as needing to be 136 to not be considered overweight). He said this was absolutely reachable, but I will need to be committed and follow an exercise plan too. He advises that the band is a tool to make the weight loss job easier, but reminds me that I have to work at it too.
Good luck with whatever path you choose to take.
