So Im going to be planning on starting a CKD diet in a few days. The thing that concerns me is what happens when you go off of it. I know you have the weekend carb up. Will you put weight back on afterwards like I know people do with Atkins

Short Answer:
People gain weight after atkins/other fad diets because they have no self control and use the diet as a way to control their eating habits.
There is probably more to it than that, but that's my 2 cents.

The atkins diet is not geared towards athletes, keep that in mind, its geared towards average people with an average perception on what the effects of dieting are.
In ketogenic diets in general, you lose water weight because of the effects of ketones as well as glycogen from the muscle (at a much more accelerated rate). Putting on "Weight" is subjective. You do not want to put on fat, but weight gain happens. If you come off of CKD and eat at maintenance level you won't gain weight back.
On the carb up weekend you should gain weight back, water in the muscles mostly from the glycogen.
What is this maintenance level in which you speak? I hear BWX15 and BWX18, is there a more accurate way to determine it? I'm taking in 3,000 calories a day and that's supposedly 600 calories lower than my maintenance, but i feel that is still too high! What is your stance on this?
The most accurate way, not to be a ****, is to find out yourself.
Say if you eat 3000 calories a day and gain .5 pounds in a week, you can almost safely say youve eaten 1750 extra calories you need a week.
Thanks guys. Another thought I had and I cant find this anywhere in the threads or articles. Everything gives good info on protein and fat intake. Being that your trying to keep as much water in the muscle as possible. Should you try to increase your Sodium and K+ intake?
At minium I would think this would help retain some strength

You'll notice alot of guys that cut with this diet get strength increases as a normal part of their cut. This diet preserves muscle very well.
I agree, potassium can be supplemented from low sodium salt. It's made from potassium and sodium.
