Energy Metabolism Overview

Questions 1 to 4 concern the following case. You see in your office a thin, anxious woman who is concerned about her weight. She is worried that she may have a parasite causing her to lose weight. She stands 5′5′′ tall (1.67 m) and weighs 101 lb (45.85 kg). For the same patient, her daily caloric needs can be estimated to be which of the following?

ExplanationThe BMR can be estimated by multiplying the weight (in kg) times 24 cal/kg, which is assuming an energy use of 1 cal/h/kg. Multiplying 45.85 times 24 yields 1,100 cal/day. Her metabolic need can be estimated by multiplying her BMR times an acitivty factor (how active the individual is). For someone who exercises 2 h/day (moderately active) the activity factor is 1.6, so her daily caloric needs are 1,100 × 1.6, or 1,760 cal/day.
