Katie has increased her weekly runs from four miles to six miles, and she's noticed that her energy levels have decreased since doing so. what should katie do to increase her energy? a) she needs to consume fewer calories to increase her energy. b) she needs to consume more calories to increase her energy. c) she needs to decrease her weekly run time back to four miles to boost her energy. d) she needs to increase her weekly run time to eight miles to boost her energy.

C) She needs to decrease her weekly run time back to four miles to boost her energy.

Explanation:

Katie increased the intensity of her physical activity quite sharply as she ran six miles and started running eight miles. Since Katie's body is used to the six-mile race, when she runs eight miles it will use up more energy. Ideally, in this case, Katie would slowly increase the miles she runs, that is, she should re-run six miles and gradually increase this distance, so that her body would react better and use less energy.
