Final answer:
The estimated daily energy requirement for a sedentary 65-year-old man who is 5 feet 11 inches tall and weighs 250 pounds, after adjusting for age, is approximately 2050 kcal/day.
Step-by-step explanation:
To estimate the energy requirements of a sedentary 65-year-old man who is 5 feet 11 inches tall and weighs 250 pounds, we start with the baseline daily caloric needs for an adult male leading a sedentary lifestyle, which could be up to 2400 kcal/day. Then, we adjust for age, subtracting 10 kcal for each year older than 30. This man is 35 years older than 30 (65 - 30 = 35), so we subtract 350 kcal (35 years × 10 kcal/year) from the baseline.
Therefore, the estimated daily energy requirement for this individual would be 2400 kcal - 350 kcal, which equals 2050 kcal/day. This estimation does not take into account individual variations in metabolism or health conditions that may affect energy requirements.
