When you say you haven't seen a lot of results -- what do you mean? Have you lost any weight or none at all?
Upping or changing your exercise routine can cause you to retain water (part of muscle repair). This could be off-setting any weight loss.
Have you taken measurements? You're probably slimming down but not seeing it on the scale.
I'd guess at your weight and that much activity, you could eat more calories and still lose. We are all different, but I lose at 1600 calories and running 4x/week.
And this is just my opinion so take it with a grain of salt... your body needs some good carbs with that much high-intensity cardio.
Back in the saddle. Again.
