I was banded on 11/18/2010 and struggled with the same question, before and after. Ultimately, I freely told my family and close friends and over time I tell people that I am comfortable telling. Others who ask me about the weight loss - I simply say that I eat a WHOLE lot less and exercise a whole lot more. Notwithstanding my fear about people's reactions, 99.9% of the reaction has been completely loving and supportive. I even had some tell me congratulations and tell me how brave I've been for taking control over my challenges. My advice - screw what other people think or say, if you want to tell them, do it, if not, don't. You've taken control and thats what matters most!
