I'm really an open book in this matter. I don't really care if my coworkers were to ask me questions, or catch me checking nutrion labels. I'm pretty open about it with my hubby, family, and friends. I never really thought about it as an issue. I even have my husband trained to check labels for me, if he goes without me to the store. I've just always been a fairly blunt and honest person, and I try not to let what others think worry me too much. But I can understand your concern, I've learned over the years that my openness is odd.
Maybe as things continue to work out for you, you'll feel more confident and proud, and more willing to talk about it.
