How do you make your belly grow?

To make your belly grow, you can focus on gaining weight through a calorie surplus, which involves consuming more calories than your body burns. This can be achieved by eating nutrient-dense foods high in healthy fats, carbohydrates, and proteins. Additionally, incorporating strength training can help build muscle mass, which can contribute to an increase in belly size. However, it's important to approach weight gain healthily and consult with a healthcare professional if needed.
