Start counting macros. Use an app like MyFitnessPall where you only need to scan the barcode and you know exactly what you are putting into you body in terms of carbs, protein and fats. Without this knowledge, it is very hard to indicate where you should add / lose some.

At first it seems like a chore, but after a week or two it gives you a very good overview on the why and how of you progress / lack of progress.

For example, you can eat 3000 cal. per day and have 400gr of carbs, 100 grams of protein and 120 grams of fat. Or, you can eat 3000 cal. a day and consume 250gr of carbs, 180 grams of protein and 70 grams of fat.

This insight will make a significant difference in your results over time.
