To calculate the Estimated Energy Requirement (EER) for men and women aged 19 years and older, you will first need to know the individual’s age, weight (in kg), height (in m), and their physical activity level (PA). Let’s break this down with a hypothetical example for both a male and a female. **Example for Men:** - Age: 25 years - Weight: 70 kg - Height: 1.75 m - Physical Activity Level (PA): 1.55 (Moderately active) Using the formula: EER = 662 - (9.53 × Age) + PA × [(15.91 × Weight) + (539.6 × Height)] EER = 662 - (9.53 × 25) + 1.55 × [(15.91 × 70) + (539.6 × 1.75)] EER = 662 - 238.25 + 1.55 × [1113.7 + 944.3] EER = 662 - 238.25 + 1.55 × 2058 EER = 662 - 238.25 + 3190.9 EER ≈ 3614.65 kcal **Example for Women:** - Age: 25 years - Weight: 60 kg - Height: 1.65 m - Physical Activity Level (PA): 1.55 (Moderately active) Using the formula: EER = 354 - (6.91 × Age) + PA × [(9.36 × Weight) + (726 × Height)] EER = 354 - (6.91 × 25) + 1.55 × [(9.36 × 60) + (726 × 1.65)] EER = 354 - 172.75 + 1.55 × [561.6 + 1198.9] EER = 354 - 172.75 + 1.55 × 1760.5 EER = 354 - 172.75 + 2739.775 EER ≈ 2920.025 kcal Thus, for the 25-year-old male, the EER is approximately 3615 kcal, and for the female, it is about 2920 kcal. Adjust the values according to the actual age, weight, height, and activity levels to find EER for any individual.
