Sounds normal to me.
You don't eat enough at your meal to satisfy the needs of your body, so you get hungry again in a short time.
I recommend you take a course in nutrition which will include the metabolic value of starches, fruits, vegetables, fats, and meats. IN addition, you can learn the harm of eating sugars. An average adult female needs about 2,000 calories a day to maintain her weight. That can break down to 500 calories a meal plus two snacks.
