Lavonne is 42-years-old and has always had to watch her intake and maintain an active lifestyle to stay at a
healthy weight. She is 5'8" tall and until a couple of months ago, maintained a healthy weight of 160
pounds, with a BMI in the normal range of 24.3. However, a couple of months ago, Lavonne was training
for her first marathon and while running, she stepped in a hole and broke her ankle. She has been unable
to keep up her training regimen and is very disappointed that she can't participate in the marathon.
Lavonne has been indulging in her favorite foods to make herself feel a little better and has gained 18
pounds and her BMI is now 27.1. She's also discovered that as she gains weight, the weight seems to be
settling in her middle as her waist circumference has increased by two full inches to 34"!
Question 1: Define energy balance and explain Lavonne's weight gain in terms of factors affecting energy
intake and all areas of energy expenditure.
Your friend insists that it is impossible to survive long-term on a vegan diet. Describe to your friend how a vegan diet can be a "healthy diet." I need a one-day eating plan (3 meals, 2 snacks) for a 40-yr old woman of an average BMI that is an athlete (marathon runner).
Emma is a 19-year-old national level elite triathlete, and she trains about 25 hours per week with 5 hours as strength exercises. Her BMI is 20, and her percent body fat is 15%. She eats a varied diet but does not like fruits and vegetables and tends to focus on carbohydrate-rich foods and meat and cheese, but because of her schedule, she eats irregularly and eats out a lot, tending towards sandwiches and wraps.

- What are Bruces options at this point? 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_forwardEmma is a 19-year-old national level elite triathlete, and she trains about 25 hours per week with 5 hours as strength exercises.
