Think about it this way:
Suppose a pound of bodyweight takes only 10 calories per day to MAINTAIN (just an arbitrary number I'm picking to illustrate a point). In that case basic math says you need 2200 calories to avoid being in a caloric deficit. What if that same pound of bodyweight takes....20 calories? Now you need 4400...JUST TO STAVE OFF DEATH.
What happens if the muscle is actively working then? Being torn down, broken up, having to rebuild, etc.? You see where I'm going with this.
Eat more food. I'm your age, 3 inches taller, and 20lbs heavier. I've tracked my calories because I thought I was eating enough, and 4000 was/is nowhere near enough when I'm pushing the limit.
