If I have a higher carb day, it's usually once a year type things, like Christmas, Thanksgiving, or a five year old brought me a piece of her own birthday cake. The piece of cake I just snap back from, as long as those birthdays aren't too close together. The bigger feast type days--I'll be hungrier for a week. Like Khrussva, my habitual diet is low carb, so I won't end up binging on off-plan foods. But I will end up eating more of the morish low carb foods, like cheese or nuts. What I do now is just let my appetite take its course, but I find if I stick to foods with a higher percentage of fat--cream cheese instead of cheddar, lower carb nuts like pecans or brazil nuts instead of peanuts or cashews--my appetite returns to normal much sooner.
