1200 is way too low you need 1500 minimum for a person of your size if you are working out vigorously everyday. Your diet should consist of a moderate calorie deficit and be high in protein. About 35-40% of your calories should be protein so that makes 130-140 grams of protein per day which will be difficult to get unless you supplement.
OHBH makes a lot of sense. You need to eat enough so your body doesn't go into starvation mode.
But you should really get some expert advice - see a nutritionist and get the real scoop
