There is a move towards low carb athletic performance... theres a kiwi guy called Jack ? in the +60 triathlete arena who went onto a paleo diet and is current world champ I think.. I read an article in north and south some time back about him.. his intake is meat (incl. organs and marrow/ligament joint tissues etc) and vegetables along with certain fats. This diet solved his joint related issues and has enhanced his performance by all accounts.
This website is about another high performance athlete doing similar..
