I honestly think it has to be the all the above answer!! I give it 100% and I have been having great success!! I journal everything, and try to make good quality food choices, I only drink water and lots of it. Of course exercise is key! I know it is alot, but after you start doing it, it become second nature! I was banded Sept 30th and as of today I am down 70 pounds! I never thought it was possible! The band works, but it is just a tool....you still have to do the work! Best of luck to you!
