What you're eating may be just fine — it varies from person to person. The best measure of need is body awareness. Rhetorical list of questions:
- Do you have plenty of energy for your workouts?
- Do you ever feel absolutely stuffed when you eat?
- Are you losing fat (not necessarily scale-weight)
- How restful is your sleep: 1) are you sleeping enough, and 2) are you sleeping deeply enough
- Are you staying properly hydrated?
I would say, give you current plan another four weeks and see where how your fat/lean-mass ratio shifts.
