You can go even lower on carbs on non-training days. If you're getting 100-150 on training days that's plenty to replenish glycogen for a lifting session, so you can go as low as you want on your days off. If you just want to cut fat then bring in some fasted low impact cardio on your off days (I'm a fan of walking on a treadmill on it's highest incline). That will get you in a good fat-burning state that will keep going until you eat carbs again.
If most of your carbs will be after training, make sure you have protein in your system BEFORE you train. I like to have protein 1-2 hours before I train so there will be amino acids already in my system when I start hitting the weights.
Currently training for raw competition.
