Calorie balance is crucial for weight management as it refers to the relationship between calories consumed and calories burned. When you consume more calories than you expend, the excess is stored as fat, leading to weight gain. Conversely, creating a caloric deficit by either eating less or increasing physical activity helps with weight loss. Maintaining a balance is essential for achieving and sustaining a healthy weight, which plays a vital role in overall well-being and reducing the risk of chronic diseases.
