What percentage of daily energy expenditure does the resting metabolic rate account for?

20-30%
30-50%
60-75%
80-90%

The correct answer is: 60-75%

Resting metabolic rate (RMR) is a critical component of daily energy expenditure, as it reflects the number of calories your body needs to maintain vital functions while at rest, such as breathing, circulation, and cellular production. RMR typically accounts for a substantial proportion of an individual's total daily energy expenditure, usually between 60% and 75%. This high percentage is due to the fact that your body is continuously expending energy for these essential processes, even when you are not actively exercising. Factors influencing RMR include age, sex, body composition, and hormonal levels, among others. Therefore, understanding RMR and its contribution to total energy expenditure is vital for personal trainers when designing nutrition and exercise programs for clients, as it helps in establishing appropriate caloric intake and expenditure strategies for weight management and overall health.
