low carb = no lifting energy...
if you are doing cardio, how fast are you doing it??? the faster and harder you go, the more glucose you will use as a proportion to calories burned... i would reco. walking for about an hour a day in the morning... you will burn almost all fat as a proportion to calories burned in this exercise...
