In continuation, during off days, I gather that you mean days between workout days.
Again, what might your total calorie intake be on off days? Also, what is your current bodycomposition intention? If you are in a bulking phase, then you might not count your carbs that much. If you intend to get lean, not only will you have to count your carbs but also, your total calorie intake.
The rule of thumb would be to bulk when your bodyfat percentage is a single digit. Once it reaches double digit (around 15 or so percent) you should start dieting down to a single digit again and in this way, make a stepwise increase in LBM over the long term.
