A 30‑year‑old female weighing \(60\) kg and \(165\) cm tall has a basal metabolic rate (BMR) given by the Harris‑Benedict equation: \( \text{BMR}=655+(9.6\times\text{weight})+(1.8\times\text{height})-(4.7\times\text{age})\). She leads a moderately active lifestyle with an activity factor of \(1.55\). (a) Calculate her BMR and her total daily energy expenditure (TEE). (b) If her diet provides \(1800\) kcal per day, determine whether she is in energy deficit or surplus and by how many kilocalories.

Answer Options

Correct Answer A. BMR ≈ 1387 kcal day⁻¹; TEE ≈ 2150 kcal day⁻¹; diet gives a deficit of about 350 kcal per day.
B. BMR ≈ 1300 kcal day⁻¹; TEE ≈ 2015 kcal day⁻¹; diet gives a surplus of about 215 kcal per day.
C. BMR ≈ 1500 kcal day⁻¹; TEE ≈ 2325 kcal day⁻¹; diet gives a deficit of about 525 kcal per day.
D. BMR ≈ 1387 kcal day⁻¹; TEE ≈ 2150 kcal day⁻¹; diet gives a surplus of about 350 kcal per day.
Correct Answer
A
Correct Option:
BMR ≈ 1387 kcal day⁻¹; TEE ≈ 2150 kcal day⁻¹; diet gives a deficit of about 350 kcal per day.
