I consider this only a minor sin. You blew the diet for that day but stayed within your WOE. That is a victory in a way and certainly better than the alternative carb fest.

I've overeaten my LC food many, many times -- especially in those first few months. I noticed that I tend to have more energy and be less hungry the next day. I honestly think that sometimes our bodies just need us to take a day off from eating at an energy deficit. After we do it, we are ready to roll again. So perhaps it does serve some purpose.
