I'm going to put in my two cents here and ask you if you are truly not concerned with weight loss. Come on, be honest...Don't you look forward to those clothes feeling a litle looser each day?
If so, then why kill yourself with this fasting buisness? In DANDR he cites studies that prove a low carb diet loses more body fat than not eating at all!
Have a think about that before you shock your bodys metabolism into starvation mode and end up adding pounds in the end.
