Question 1

Which eating pattern is characterized by alternating periods of fasting and unrestricted eating within a 24-hour cycle?

Accepted Answer

Intermittent fasting

Answer

Intermittent fasting uses structured fasting windows (e.g., 16:8 or 5:2 protocols) alternated with normal eating periods to reduce overall caloric intake.

Question 2

A client is losing weight but reports feeling constantly cold and fatigued. Which metabolic adaptation is most likely occurring?

Accepted Answer

Adaptive thermogenesis (metabolic adaptation)

Answer

Adaptive thermogenesis is a downward shift in resting metabolic rate beyond what is predicted by body composition changes, commonly triggered by prolonged caloric restriction.

Question 3

Which waist circumference threshold indicates substantially increased metabolic disease risk for women, according to NHLBI guidelines?

Accepted Answer

Over 35 inches

Answer

The NHLBI identifies a waist circumference greater than 35 inches (88 cm) in women as a threshold for substantially increased risk of metabolic disease.

Question 4

Visceral adipose tissue is considered more metabolically dangerous than subcutaneous fat primarily because it:

Accepted Answer

Releases inflammatory cytokines and free fatty acids directly into portal circulation

Answer

Visceral fat drains into the portal vein, delivering inflammatory cytokines and free fatty acids directly to the liver, driving insulin resistance and metabolic syndrome.

Question 5

Which macronutrient has the highest thermic effect of food (TEF), meaning the body expends the most calories digesting it?

Accepted Answer

Protein

Answer

Protein has a TEF of approximately 20–35%, meaning up to one-third of its calories are burned during digestion and absorption.
