When you eat, don't need to eat until full or satisfied. As long as not hungry, it is good enough. Train yourself to eat less. You can continue to indulge in junks once a while. Since you are still doing workouts, it is fine.

Slowly train your body to eat less. You can also train yourself by eating less carb. Eat more protein if you want. Try to stay away from sugar. Like those ice cream are really fatty. Just keep them at low consumption.

Most of all, don't worry too much since your weight is still under control. Enjoy the food and continue to workout.
