The concept of calorie balance in weight management refers to the relationship between calorie intake and energy expenditure. Achieving a healthy weight involves consuming an appropriate number of calories to match the energy used through daily activities and exercise. A calorie surplus leads to weight gain, while a deficit results in weight loss. Understanding one’s individual metabolic rate and activity level is essential for establishing an effective caloric target. A balanced approach, including nutrient-dense foods and regular physical activity, promotes sustainable weight management and overall health.
