Chapter 16, Problem 1.1CS
Summary Introduction
To determine: The amount of calories required by Person K to maintain her body weight.
Introduction: The status of the weight of individuals is estimated by their body mass index (BMI). BMI is calculated by dividing the weight of a person in kilogram by the square of height in meters. Resting energy expenditure (REE) is defined as the amount of energy expended by a person during a non-active period (at rest).
Expert Solution & Answer
Explanation of Solution
Person K who is 25 years old has a weight of 135 pounds (61.23 kg) and a height of 5 foot 8 inches (172.72 cm). During her high school, she actively participated in various competitive sports. Also, she decided to run a marathon with some of her college friends. Usually, she eats all varieties of fruits and vegetables and tries to avoid greasy foods. Daily, she used to drink around 4-6 cups of coffee. She does not like sweets. Her mother requires angioplasty in order to treat occluded arteries just after menopause and also her father is not at any risk under any chronic conditions. Person K is not pregnant although she wishes to have children.
The Resting energy expenditure (REE) can be calculated using a validated estimation formula. The Mifflin-St. Jeor formula requires accurate measures of height in cm and weight in kg using the formula given below:
Person K has a weight of 135 pounds (61.23 kg) and height of 5 foot 8 inches (172.72 cm) tall. Then, the REE of Person K is calculated as follows:
After determining the REE, the obtained value of REE is multiplied by an activity factor of 1.725, owing to the high activity level of Person K, to obtain the estimated daily calorie requirement:
Thus, the daily energy requirement for Person K is 2425 cal to maintain her weight.
Conclusion
Person K needs 2425 calories to maintain her weight.

Bruce and his parents moved to a semi-tropical region of the United States when he was about 3 years old. He loved to be outside year-round and swim, surf, snorkel, and play baseball. Bruce was fair-skinned, and in his childhood years, was sunburned quite often. In his teen years, he began using sunscreens, and although he never tanned very much, he did not have the painful sunburns of his younger years. After graduation from the local community college, Bruce wanted an outdoor job and was hired at a dive shop. He took people out to one of the local reefs to snorkel and scuba dive. He didnt give a second thought to sun exposure because he used sunscreen. His employer did not provide health insurance, so Bruce did not go for annual checkups, and tried to stay in good health. In his late 20s, Bruce was injured trying to keep a tourist from getting caught between the dive boat and the dock. He went to an internist, who treated his injury and told Bruce he was going to give him a complete physical exam. During the exam, the internist noticed a discolored patch of skin on Bruces back. She told him that she suspected Bruce had skin cancer and referred him to a dermatologist, who biopsied the patch. At a follow-up visit, Bruce was told that he had melanoma, a deadly form of skin cancer. Further testing revealed that the melanoma had spread to his liver and his lungs. The dermatologist explained that treatment options at this stage are limited. The drugs available for chemotherapy have only temporary effects, and surgery is not effective for melanoma at this stage. The dermatologist recommended that Bruce consider entering a clinical trial that was testing a DNA vaccine for melanoma treatment. These vaccines deliver DNA encoding a gene expressed by the cancer cells to the immune system. This primes the immune system to respond by producing large quantities of antibodies that destroy melanoma cells wherever they occur in the body. A clinical trial using one such DNA vaccine was being conducted at a nearby medical center, and Bruce decided to participate. At the study clinic, Bruce learned that he would be in a Phase Ill trial, comparing the DNA vaccine against the standard treatment, which is chemotherapy, and that he would be randomly assigned to receive either the DNA vaccine or the chemotherapy. He was disappointed to learn this. He thought he would be receiving the DNA vaccine.arrow_forward
