Q: A 40-year-old woman weighs 70 kg, is 1.7 meters tall, and has a physical activity (PA) value of 1.12. Calculate her Estimated Energy Requirement (EER) using the formula for adult females.

$$EER = 354 - [6.91 \times 40] + 1.12 \times [9.36 \times 70 + 726 \times 1.7] = 354 - 276.4 + 1.12 \times [655.2 + 1234.2] = 77.6 + 1.12 \times 1889.4 = 77.6 + 2116.13 = 2193.73$$
