I keep noticing that everyone keeps saying just because they ate carbs that their weight shot back up. It's not fat. You cannot gain 3-5 lbs of fat in a few days. Just to let you girls know that each gram of carbohydrate holds 4 molecules of water in your system. And, when you ingest a carb, whether it be simple or complex it goes to your muscle fibers. The weight gain that you see is simply glycogen and water that's all!

It come right back off when you restrict your carbs again. Here is a tip, (not that you should always cheat on your diet), but when you DO cheat, do moderate intensity cardio to help kick yourself back into ketosis quicker, and high intensity cardio gets rid of the gylcogen in your muscles.
