Using the Mifflin-St.Jeor equation for men (below) and a stress factor of 1.3, estimate the energy needs of Mr.Briggs, who is 33 years old, is 173 cm tall, and weighs 67 kg. RMR = [9.99 *weight (kg)] + [6.25* height (cm)] - [4.92 * age (years)] + 5

First, we calculate the RMR using the Mifflin-St.Jeor equation for men:

RMR = [9.99 x 67] + [6.25 x 173] - [4.92 x 33] + 5
RMR = 669.33 + 1081.25 - 162.36 + 5
RMR = 1593.22 kcal per day

Next, we apply the stress factor of 1.3:

Energy needs = RMR x Stress factor
Energy needs = 1593.22 x 1.3
Energy needs = 2070.2 kcal per day

Therefore, the best choice is C, which is 2071 kcal. RMR = [9.99 x 67] + [6.25 x 173] - [4.92 x 33] + 5 = 1,608.83 kcal/day
Energy needs with stress factor = RMR x stress factor = 1,608.83 x 1.3 = 2,090.48 kcal/day, which is closest to option C, 2071 kcal.
