Question 2

Calculate an estimated energy requirement for a 24-hr period using a simple formula.

Accepted Answer

To calculate an estimated energy requirement for a 24-hour period using a simple formula, you can use the Harris-Benedict equation. For men, the formula is: 
BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)

For women, the formula is:
BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

Once you have calculated the Basal Metabolic Rate (BMR) using the appropriate formula, you can then multiply it by an activity factor to estimate the total energy requirement for a 24-hour period. For example, if the person is sedentary, you would multiply the BMR by 1.2. If the person is moderately active, you would multiply the BMR by 1.55. And if the person is very active, you would multiply the BMR by 1.725.

By using these formulas and activity factors, you can estimate the energy requirement for a 24-hour period based on an individual's weight, height, age, and activity level. Keep in mind that this is just an estimate and individual variations in metabolism and activity levels should also be considered.
