Im only about 6 - 10 lbs heavier than you, same height, BMI barely 35. Im getting the band. My goal is about 140-150. I get the same reaction from people who say "your not even that heavy" but im at the same time, people refer to me as "that heavy girl".
I love steak, am I am willing to accept the change in what I eat because it is these foods and lack of adequate exercise that keeps me at this weight. So keep that in mind. Ive also been on a diet for the last 5 months and havent really lost any weight. Ive been up and down. Hopefully the pre-diet will help you gradually adjust to the new eating lifestyle.
