Final answer:
Basal metabolic rate typically accounts for 70 to 75 percent of the daily total energy expenditure, with factors like muscle mass and activity level influencing individual differences.
Step-by-step explanation:
The amount of daily total energy that basal metabolic energy expenditure (BMEE) or basal metabolic rate (BMR) accounts for varies but is typically around 70 to 75 percent. BMR represents the energy needed for maintaining the basic functions of the body's organs while at rest. An additional 20 percent of energy expenditure is usually from physical activity, and the remaining 10 percent helps with body thermoregulation or temperature control. Factors that can influence BMR include age, gender, total body weight, muscle mass, and activity level. Athletes may have a higher BMR due to increased muscle mass.
