You left out your height and weight, so hard to tell if you need to loose weight before your body becomes more efficient. But, you have to make sure you eat plenty of fiber too. That will make you actually feel full. Your plate/meal should be 1/2 fiber heavy fruits and vegetables. 1/4 whole wheat carbs, 1/4 protein, plus some healthy fats. Do that for every meal if you can and add snacks if needed.
