well in my last fight i fought at 170 and im 6'2" but ever since being on this diet ive lost weight and im like 160 so i could probably drop to 155. I train 5 to 6 times a week. Monday through thursday, 5-8 weightlifting, brazilian jujitsu, kickboxing (1 hour each). Friday i do some lifting and light sparring. Saturday its in the morning from 930-12 its 930-11 team mma (go over different stuff in the cage), 11-12 is boxing. Sunday is day off. But im really struggling to get through all those workouts, do you think that my body just needs to adapt at using fat as main source of fuel? or can i simply not do it without carbs?
