Even at a 109 grams of carbs, that is still considered low compared to your total calorie intake. At this percentage of carb intake, I don't think you're going to see any difference, in terms of energy, from your carb choices. The volume of carbs is what's going to make the biggest difference. Since your body has been previously dependent on higher amounts of carbs, it will take several weeks before it becomes adapated to using stored and ingested fat more effeciently for fuel.

Regarding your workouts, I would reconsider what you are currently doing for something less taxing on the nervous system. With your Martial Art training, the last thing you need is muscle soreness/fatigue and a nervous system that takes days to recover because of the stress put on it by working your sets to failure. A better aproach would be to alternate between as few a exercises each workout as it takes to cover as many muscles as you can. An example of this, would be something like, power clean and press, 5 sets of 5 reps, or 5x2, 3x3, 4x2 etc. Deadlifts, pull-ups and some bent or side presses would be another example. Working somewhere between 75-95% of your 1 rep maximum avoiding failure. By doing this, you'll be able to repeat the same routine on alternating days. The benefit, is a tonic like effect on the nervous system, great muscle tone and strength. Use your martial arts training days to work your endurance and/or strength endurance.
