Hi, I have been low carbing for months and have been on about 20g of carbs a day. As I'm also interested in following the primal diet I was wondering about ketosis, in that from what I understand one needs to be eating under 50g of carbs to be burning fat but lots of you seem to be eating 100g to 300g of carbs? Doesn't this mean you are no longer in ketosis and burning the extra carbs as glucose as the only other source of fuel? Can someone explain it to me?
