Quizplus · Accepted Answer

As people age, their metabolism and overall muscle mass decrease, which lowers their energy needs. It is estimated that energy needs decrease by about 2-3% per decade after the age of 30. Therefore, an 80-year-old man like Louis would have a decrease in energy needs of approximately 50-75%, which translates to a decline of 25% compared to when he was 30 years old.
