I'm not aware of any dietary fat requirement to enter or maintain ketosis. I've talked to others that mention a protein/fat ratio but I've not see any literature about it. Citation appreciated. A low carb and low fat diet is unhealthy for lean people because fat/fatty acids/etc is required for a whole lot of synthesis.
