Good advice Edgar. It is wise to introduce small amounts of carbs per meal into your diet and slowly taper your carb intake up during the first 2 or so weeks.
This will also help reduce the severity of the water retention rebound that you will get from eating carbs again. But that weight will also balance back out in 2-3 weeks, so don't panic. You shouldn't have much of a problem anyway since you weren't on the keto diet for that long.
