                                Accounting for a significant 60-70% of a person's total daily energy expenditure, basal metabolic rate (BMR) is often confused with standard metabolic rate (SMR). Understanding what is the difference between BMR and SMR is crucial for distinguishing between animal metabolism studies and specific human metabolic measures.
