Question

2556 kcalories per day for a 30-year-old woman who is 5 feet 5 inches tall, weighs 150 pounds, and has a low activity level. To estimate the

energy requirements of a similar 50-year-old
woman, subtract 7 kcalories per day for each
year older than 30:_____________

Answer 1

To estimate the energy requirements of a 50-year-old woman, subtract 7 kcalories per day for each year older than 30 from the energy requirements of a 30-year-old woman. The energy requirements for the 30-year-old woman are given as 2556 kcalories per day. So, for a 50-year-old woman with low activity level, the energy requirements would be 2416 kcalories per day.

Step-by-step explanation:

To estimate the energy requirements of a 50-year-old woman, we subtract 7 kcalories per day for each year older than 30 from the energy requirements of a 30-year-old woman. The energy requirements for the 30-year-old woman are given as 2556 kcalories per day.

So, for a 50-year-old woman with low activity level,

Energy requirements = 2556 kcalories per day - (7 kcalories per day x (50 - 30))

= 2556 kcalories per day - (7 kcalories per day x 20)

= 2556 kcalories per day - 140 kcalories per day

= 2416 kcalories per day
