2026 COMPLETE QUESTIONS AND
SOLUTIONS 100% CORRECT
◉ What is resting energy expenditure (resting metabolic rate) Answer:
the amount of energy needed for the body to maintain homeostasis and
normal organ function at rest; 75% of RMR come from organs that make
up less than 10% of body weight (brain, heart, kidneys, liver, gut)
◉ How do you estimate RMR? Answer: equations based on bw, age,
gender, but no lean mass; Cunningham uses lean masses with is more
accurate: REE=500+22*(lean mass); indirect calorimetry that measures
o2 and co2 to calculate REE
◉ What are other factors that affect RMR in an individual? Answer:
SNS: psychological stress, physical stress; Thyroid hormone: Potentiates
sympathetic nerve activity, very strong impact on metabolic rate:
directly affect the efficiency of mitochondrial respiration,
hypothyroidism: significant weight gain, hyperthyroidism: significant
weight loss; hypocaloric diet
◉ What is diet-induced thermogenesis? Answer: 10% of total daily
energy intake is lost to digest food and absorb nutrient; lipid is the least
thermogenic (5-7%), protein (20-35%), and carbohydrate (10-15%)
