You may want to go on Induction for at least a few days to get your body back into ketosis. This is especially true if you ate high carb foods when you slacked off. I urge you to try and stick with the plan and not eat higher carb foods. When you go in and out of ketosis repeatedly it seems to become less effective. Also, you run the risk of readdicting yourself to high carb foods and/or sugar (if that was a problem for you) anytime that you start eating them again.
