HNF 471 - EXAM 3 QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++
What is the specific cause of weight gain?
Energy intake > energy output
Define homeostatic
Eating that is driven by caloric deficit and hunger. Palatability not important.
Define hedonic
Eating that is driven by pleasure. Palatability is key.
Define satiation
A measure of fullness that signals the end of an eating occasion (how full you are).
Define satiety
A measure of time to next eating occasion (time between meals).
What are satiety and satiation both influenced by?
Hormones
All hormones decrease the effect satiation has on food intake EXCEPT
Ghrelin (increases it)
What are insulin and leptin secreted based on?
Body fat stores (more fat = bigger secretion)
What is the individualized diet kcal value MNT during weight loss reccomendation
for females? Males?
Females: 1200 - 1500 kcal/day
Males: 1500-1800 kcal/day
, Besides a calorie reduction, what are two other ways weight loss can be managed
post gastric bypass surgery?
- an energy deficit of 500 - 750 kcal/day
- an evidence-based diet that restricts certain food types (high-CHO, low-fiber, or high-
fat) to create negative energy balance)
What two factors are associated with a higher risk of regaining weight post
gastric bypass surgery?
- decreases in leisure-time physical activity, dietary restraint, and frequency of self-
weighing
- increases in percentage of energy intake from fat disinhibition
Define metabolic adaptation
Slowing of resting metabolic rate (RMR) that is often greater than would be expected
based on measured changes in body composition. This happens to individuals who
maintain a greater weight loss after surgery.
True or False: carbohydrates are stored with H2O
True! By depleting glycogen reserves, water goes with. This results in rapid but
temporary weight-loss.
What is the mechanism for Ozempic?
It is a GLP-1 analog (activator). GLP-1 is the hormone that makes you feel full, and by
taking Ozempic it activates it which causes you to feel fuller for longer, ultimately
resulting in weight-loss.
What are the 3 categories of gastric bypass surgery?
