Surely possible! I've had clients in this same predicament that weren't seeing results because they were eating too low. And like I/we said, at 1600 calories and a vigorous cardio session you're left with 1000 calories. Do this enough and you're either wasting away, what I call burning up muscle at the expense of losing weight, or your body is gonna do its damnest to soak up more water and hold more fat when it gets a chance, due to the over-stress.
