Calorie balance plays a critical role in weight management, as it involves the relationship between calories consumed and calories expended. Achieving weight loss requires a caloric deficit, whereas maintaining or gaining weight necessitates balance or a caloric surplus. Understanding personal daily energy needs, influenced by factors like age, gender, and activity level, is vital for effective weight management. Making informed dietary choices and incorporating physical activity can help individuals achieve desired weight goals, fostering long-term health and wellness. Tracking both caloric intake and expenditure promotes better control over weight management strategies.
