"Do I eat my exercise calories?"

rachel1496

I have lost 20kg so far and the medthod I have used is:
Eat c 1200 Calories per day (any less probably puts you in starvation mode)
Exercise c 700 - 1400 Calories per day (Cardio and some weights)

I never eat the calories I have burnt and thus have a deficit, technically some times my weight loss is not matched by the calorie deficit but it always moves in the correct direction

I think I'm misunderstanding something here. If I eat 1200 and burn 1400 through exercise I would end up with a 200 calorie deficit on top of my 2550 TDEE, so a 2750 cal deficit per day. Can that possibly be healthy?
