No, you are not getting enough calories. In order to ensure basic nutrient needs for your body's metabolic function, it's important that you get AT LEAST 1200 calories. Otherwise, you will suffer from nutritional shortages that can slow your metabolism over time. This also has the unpleasant side effect of causing increased weight gain when you return to normal eating habits.
May I ask why you are on a 1200 calorie diet with 70 lbs to lose? With that much to go, you should be able to eat significantly more than that and still lose weight.
