Outline the procedure of determining the total daily energy demand?

1. Calculate Basal Metabolic Rate (BMR): This is the amount of energy required to maintain basic bodily functions at rest. BMR can be calculated using equations such as the Harris-Benedict equation or the Mifflin-St Jeor equation, taking into account factors such as age, gender, weight, and height.

2. Factor in Physical Activity Level (PAL): Determine the individual's level of physical activity using a PAL value, which represents the ratio of total daily energy expenditure to BMR. PAL values range from sedentary (1.2) to very active (2.4), with higher values indicating higher levels of physical activity.

3. Calculate Total Daily Energy Expenditure (TDEE): Multiply the BMR by the PAL to determine the total daily energy expenditure. This accounts for the energy required for both basic bodily functions and physical activity.

4. Adjust for Specific Factors: Consider additional factors that may affect energy expenditure, such as pregnancy, breastfeeding, illness, or specific dietary requirements. Make adjustments to the TDEE calculation as needed to account for these factors.

5. Determine Total Daily Energy Demand: The total daily energy demand is the amount of energy required to meet an individual's daily needs, taking into account both BMR and physical activity levels. This value can be used to guide dietary intake and ensure that energy needs are being met for optimal health and performance.
