Welcome to the TDC. I can relate to not wanting to call attention to the way you are eating in a restaurant or anywhere. I used to not say anything at all. Now I ask for double vegetables instead of the potato/rice, but aside from that I don't feel any need to draw attention to myself -- it is usually pretty obvious what I can and cannot order.

Please consider doing some exercise -- it's so important for your health even if you can lose weight without it. You don't need to go to a gym; just walking around the block gets your circulation moving.
