A female worker eats three meals each day that are nutritionally well balanced. She sleeps 8 hours each night, and her average energy expenditure rate while sleeping is assumed to be her basal metabolic rate. Her job consists of office work as follows during the eight-hour shift (percentages based on time): • 10 percent walking (assume 2.8 miles/hr), 25 percent standing, and 65 percent seated. During the eight hours when she is not working, her activities consist of the following: • resting, 7.0 hr; jogging, 30 min; and • standing, 30 min. Her digestive metabolism is assumed to be 10 percent of the total of her basal and activity metabolic rates over the 24-hours of the day. The woman is 30 years old and weighs 125 lb.
