You could do a few things here:
1 - Cut back a little on the calories, maybe 2500 on lifting days, and then 2200 on non-lifting days or something.
2 - Add in more cardio (this is the one I would recommend) - Go for a walk for a 30-60 minutes, throw in some HIIT at the end of your training sessions. For those of us who dont stay naturally lean this is typically the answer.
3 - Make sure your training sessions are physically demanding enough to warrant a big increase in calories. Meaning, if you have an "arms day" you probably dont need as many calories as you do on Leg day.
Keep lifting, keep eating, keep doing cardio and then report back to us with your new results.
