I must say, I have absolutely felt more dehydrated since starting this WOE (Unfortunately this is my 3rd start). When I am following other plans or just simply eating what I want, I find that I only have 1 or 2 drinks throughout the day and I still don't get thirsty. I know it's very unhealthy so I don't need information on it, this thread has provided enough stats already! In any case, with the Atkins WOE, I crave water 24/7. I have no problems reaching the eight 8 oz. glasses of water. I'm thirsty all day. It's one of the only reasons I keep trying this plan. I just can't force myself to get proper water intake otherwise. I would have to agree with Becky. I think high protein diets do require a higher water intake. Before I get any slack from other people, no, I'm not a research scientist so I am certainly not an expert on the subject and would never pretend to be, I just know what my body is telling me and I think that's one of the best things to listen to.
