I am trying to cut some body fat .. i weigh 190 have some good muscle mass but want to cut back the extra layer- wondering how long is it safe to do a 50, 30 20 split and i forgot if the 30 is fat or carbs/ i also have "chronic fatigue" so i can't do alot of cardio..but i do walk or spin for 10min increments through out the day for a total of 30 to 40 mins.. and i have been lifting weights for a while at the gym.. thanks.
