Question

Quizplus · Accepted Answer

The basal metabolic rate is the energy the body needs to carry out basic functions when at rest. Therefore, the best time to measure it is when the animal is resting and has not eaten its first meal of the day, as this will give the most accurate baseline measurement. Eating or exercising can increase the metabolic rate and give a falsely elevated reading. A long period without water could also affect the metabolic rate and lead to false readings. A sugar-free meal is not relevant to measuring basal metabolic rate.
