This refers to the number of calories that an average person needs to consume to maintain their weight and meet their daily energy requirements. This value serves as a guideline for nutritionists and dieticians when creating meal plans and recommending calorie intake for individuals. It is important to note that this value may vary depending on factors such as age, gender, activity level, and overall health. Additionally, individual requirements may also differ based on specific health conditions or goals. Therefore, it is always advisable to consult a healthcare professional for personalized nutrition advice.
