The basal energy rate is the daily amount of energy (measured in calories) needed by the body at rest to maintain body temperatu

katovenus [111]

Given :
A = 70 years old
H = 172 cm
W = 55 kg

so calculate the the basal energy rate B
B = 655.096 + 9.563W +1.85H - 4.676A
where B is the basal energy rate (in calories), W is the weight (in kilograms), H is the height (in centimeters), and A is the age (in years)
substitute the given
B = 655.096 + 9.563(55) +1.85(172) - 4.676(70)
B = 1171.941 cal is the basal energy rate, since he is prescribed for 1000 cal per day is not enough because basal energy is the calorie needed at rest only how about the calorie needed for the daily acivities.
