Less going in than burning off and not losing weight, any ideas


Hi guys

I'm eating clean and losing all foods with my fitness pal, I'm using more calories than I'm eating so should be losing weight, I'm taking around 2000 - 2300 a day I train 6 days a week, I am 5foot 7 and 90kg, I'm trying to get back to my fighting weight of 75kg after time off with injuries, I'm doing strength and conditioning in the morning and mma in the evening, altogether I'm doing around 12 to 15 hours of training a week and I even run 5 km twice a week, I've never had this problem before. Anyone got any ideas????
