also im thinking along with water the first 3 days your muscles were still insulin resistance but now they are geting insulin sensitive
your body makes more insulin receptors on your muscles while doing low carb Atkins diet so they grow just as good as a high carb diet or better
and worked muscles will soak up all the carb glucose and protein converted glucose so you get extra fat loss benefits
thanks for posting your exp,stats and findings i really like seeing stuff like this cause im a body builder xD
but more so cause i have a freind at the gym whos somewhat pre diabetic and i want him to go on the Atkins diet but hes worried that he will lose his muscle if he does. so seeing things like this i can show him that he wont lose his muscle
so hope you can keep posting your success for awhile longer
also heres a couple useful videos about this stuff
