NFS284 Final Exam with correct answers
100% 2024
BMI - Correct Answer measure of healthy body weight that looks at weight and height
normal BMI - Correct Answer 20-25
high BMI - Correct Answer 25+, about 60% of Canadians are overweight or obese
obesity - Correct Answer increases the risk for type 2 diabetes, breast cancer and colon cancer
cancer - Correct Answer mutations occur that cause a cell to grow uncontrollably without repair and are
resistant to cell death, causing a malignant tumour
weight stigmatization - Correct Answer negative attitudes, mistreatment and discrimination based on
weight status, particularly negative attitudes toward the obese
total energy expenditure (TEE) - Correct Answer all of the energy expended in the body combined
basal metabolic rate (BMR) - Correct Answer energy needed to support the involuntary processes of
life; decreases with weight loss, adaptation to starvation
physical activity takes up how much of the TEE? - Correct Answer 15-30%
food/diet-induced thermogenesis takes up how much of the TEE? - Correct Answer 10%
energy expended in digestion - Correct Answer protein digestion expends the most energy,
carbohydrates intermediate and fat the least amount of energy consumed
energy balance - Correct Answer energy consumed is equal to the energy expended, weight unchanged
, positive energy balance - Correct Answer more energy consumed than expended, weight gain
negative energy balance - Correct Answer more energy expended than consumed, weight loss
visceral fat - Correct Answer fat accumulated at the centre of the body (stomach), highest obesity risk
and increases risk of diabetes and heart disease
hunger - Correct Answer internal signals that cause someone to want to eat
satiety - Correct Answer feeling full after a meal, determines when the next meal will occur
satiation - Correct Answer feeling of fullness that develops during a meal, determines when the meal

at/around
ghrelin - Correct Answer stimulates hunger, in obese individuals levels don't decline as much after a
meal so they eat more
GLP-1 - Correct Answer suppresses hunger and food intake by stimulating insulin release, less in obese
individuals so they eat for longer
leptin - Correct Answer regulates food intake by reducing it when there is more fat tissue, obese
individuals have more leptin and so they are not sensitive to the signal to stop eating; will eat more
insulin - Correct Answer suppresses food intake, obese individuals have more and are at higher risk for
insulin resistance, will keep eating even when insulin says to stop
adaptive thermogenesis - Correct Answer maintains set-point; may increase or decrease energy
expenditure (overeating increases it, undereating conserves energy)
