Question

Quizplus · Accepted Answer

Exercise levels have the greatest impact on an individual's basal metabolic rate. Regular exercise increases muscle mass, which in turn increases the number of calories burned at rest. Therefore, individuals who engage in regular physical activity have a higher basal metabolic rate than those who are sedentary. Caloric intake, sleep habits, and balanced diets can also affect metabolism, but to a lesser extent compared to exercise.
