Answer 2

Increase Energy Expenditure

Performing bodily functions and physical activities increases energy expenditures above basal energy by about 15% to 35%. It can also be altered by age, gender, and even menstruation. The inactive metabolic rate has a basis for total energy expenditure. Due to any kind of exercise or activity metabolic rate increases, energy expenditure also increases and vice versa.
