Describe the roles of BMR and several other factors in determining an individual’s daily energy needs. a.

Gender—women generally have less lean body mass than med; in addition, women’s menstrual hormones influence the BMR, raising it just prior to menstruation ii. Age—the BMR declines by an average of 5% per decade iii. Physical Activity—activities are grouped according to their intensity iv.
