This is way, way way overkill on so many levels. 1200-1400 calories whilst training like a professional athlete? Christ. If you are doing HIIT properly you wont be able to go more than 20 minutes a session, the LIC is fine but the diet is not, you are starving yourself. You are miles under your BMR which will produce fat/muscle loss as it is...throwing in training to that level is going to be counter productive and very catabolic. Form a proper carb cycling diet with a moderate amount of healthy fats. Your body requires energy you cant just load it with protein and nothing else and expect to see results, you need an energy resource.

Sorry if this seems harsh man but its a lot harder to build muscle than lose fat so you want to hang onto the muscle you do have and smash fat the right way. You are obviously dedicated and driven to reach your goals but you need constructive criticism to get there.

With that amount of training I don't see why you would want to dip that low in caloric intake. I try to stay 75% of my TDEE, 70% at min. I think you're dipping well into the 60% range, probably less with all the work your putting in. Watch out for any rebound effect once your diet goes back to normal. Pretty sure you will hit whatever weight your aiming for though.
