Actually, you aren't depriving yourself of carbs, because veggies are carbs, just not starchy carbs.
One way to get around people asking why you aren't eating bread is to say you don't like bread, or you are allergic to wheat. Or "Bread fills me up too fast." Even when not eating low carb, I get questioned when I turn down cake at a birthday party. So many time they say, "Oh, a little piece won't hurt you." But I actually don't like cake, or most sweets. The only exception is Hershey Kisses. I use no sweetener in coffee, and just a smidgen in tea. My DIL is constantly baking cookies and bringing them to me. I have told her repeatedly that I don't like sweets, and her father is diabetic, so she should understand that I shouldn't be eating that stuff. Her parents both do Atkins. She would never think of taking baked goods to them. The fact that I don't like sweets will make Atkins easier for me.
IF not now, when?
