I have a reputation for not liking sugar and thinking that most desserts are too sweet. The degree that I would have disliked sugar, sans my reputation for disliking it, has become blurry. Not sure where other people's expectations of me stop and my own preferences begin.

I also find the response from others, is generally more positive in their opinion on why you are refraining from sweets, if it is because you don't like it. There is something about people that likes to tempt others in to failure, and not maliciously. For example, if someone is having a cookie and someone else is in the room who also likes to eat cookies, but is controlling their impulses, you will might hear "come on just have one with me" or even guilting them or mock their diet. No one does this to me because they know me as a person who does not like sugar.
