Igcse Model Questions Vol1 2023 Biology Question 4
Practice objective / multiple choice question 4 from the 2023 Igcse Model Questions Vol1 Biology examination.
A 25‑year‑old female weighs 60 kg and is 165 cm tall. Her basal metabolic rate (BMR) can be estimated using the Harris‑Benedict equation: \(BMR = 655 + 9.6\,W + 1.8\,H - 4.7\,A\), where \(W\) is weight in kg, \(H\) is height in cm and \(A\) is age in years. She has a moderate activity level with an activity factor of 1.55. (a) Calculate her total daily energy expenditure (TDEE). (b) If she consumes 200 kcal less than her TDEE each day, estimate how much weight she would lose after 30 days, assuming that a loss of 7700 kcal corresponds to 1 kg of body weight.
