well, cardio has really done alot for me, so i cant really say its the least important thing in burning fat, its been my primary form of exercise the whole way, so i guess its important if u have a body type like mine which was 280lbs and basically a 25-30% bf. not to mention, i quit smoking the same time i started a low carb diet and i could barely run 3 or 4 minutes without choking and at 4mph. i actually have built some degree of endurance in 3months and love the feeling of running. cardio has been very important to someone like myself.
i have read that most people do eat carbs for pre or post workout, but the thing is i want to remain in ketosis so i really want to stay away from carbs. occasionally i add some rice or good veggies into my diet for variety, but i really have no issues just eating fat and protein. If its not necessary to eat carbs, id rather not, as i eat lots of everything else which should satisfy my energy level. so, is eating under 20 carbs a day while beginning to lift weights a bad thing in my particular situation? if i indeed should eat them before or after a workout and drop out of ketosis, is that a smart move?
