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

    Answer: Intermittent fasting

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

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

    Answer: Adaptive thermogenesis (metabolic adaptation)

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

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

    Answer: Over 35 inches

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

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

    Answer: Releases inflammatory cytokines and free fatty acids directly into portal circulation

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

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

    Answer: Protein

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

  6. A client following a 1,500 kcal/day plan loses weight for 8 weeks then plateaus. The MOST appropriate first intervention is to:

    Answer: Reassess current intake and body weight to recalculate energy needs

    Before adjusting the plan, a nutrition coach should verify adherence and recalculate TDEE based on the client's new (lower) body weight, as energy needs decrease with weight loss.
