From what I have been reading, (and based on the fact that I lost 17 pounds my first week on low carb and cured my edema), there is considerable glycogen bound up with water when you eat a diet with carbs which gets used up when you go into ketosis. It only makes sense that some of this water weight would come back once you go back to eating (limited quantities) of carbs - at least that's my theory.

I am wondering if some people eat a few carbs and see 6-10 pounds come back and freak out when its just water, so that will be my test. When I hit 170 I'll try something like going to 50 carbs a day for a couple of weeks and I wont freak out unless my weight goes over 180 - or perhaps I'll go down to 160 if I am going to keep 170 my permanent target...

Anyways, it will be fun to experiment
