The 20 questions

  1. What does basal metabolic rate (BMR) measure?

    • Energy at rest
    • Maximum physical output
    • Total daily activity
    • Digestion energy cost

  2. Which body component significantly increases a person's BMR?

    • Body fat percentage
    • Bone density
    • Adipose tissue
    • Lean muscle mass

  3. Which factor naturally lowers a person's BMR over time?

    • Ageing
    • Growing taller
    • Increasing body muscle
    • Regular weight training

  4. What is physical activity level (PAL) used for?

    • Determining protein intake
    • Calculating water needs
    • Estimating total energy
    • Measuring body fat

  5. A person has a BMR of 1,500 kcal and a PAL of 1.5. What is their estimated daily energy need?

    • 3,000 kcal
    • 1,000 kcal
    • 1,500 kcal
    • 2,250 kcal

  6. Apart from age and gender, what primarily affects BMR?

    • Body composition
    • Height alone
    • Daily water consumption
    • Blood pressure

  7. Why should meal portions typically be reduced for older adults?

    • Larger muscle mass
    • Lower energy needs
    • Increased daily exercise
    • Higher metabolic rates

  8. Which type of job results in the highest physical activity level value?

    • Retail cashier
    • Office manager
    • Desk job
    • Heavy manual labour

  9. What term describes when energy intake matches total energy used?

    • Energy surplus
    • Energy deficit
    • Energy metabolism
    • Energy balance

  10. Which adult group typically has a higher basal metabolic rate?

    • Elderly women
    • Adult men
    • Adult women
    • Sedentary adults

  11. Why do teenagers generally require more energy than adults of the same weight?

    • Lower height
    • Higher fat
    • Less sleep
    • Rapid growth

  12. A student's BMR is 1,400 kcal and their PAL is 1.7. Which is the closest estimate of total daily energy?

    • 1,700 kcal
    • 1,400 kcal
    • 3,100 kcal
    • 2,380 kcal

  13. Which body tissue is more metabolically active and burns more energy at rest?

    • Bone tissue
    • Adipose tissue
    • Muscle tissue
    • Subcutaneous fat

  14. A person has a BMR of 1,800 kcal and a PAL of 1.4. Which is their estimated daily energy need?

    • 3,200 kcal
    • 1,400 kcal
    • 2,520 kcal
    • 1,800 kcal

  15. Which factor causes the greatest long-term change in a person's total energy needs?

    • Activity level
    • Eye colour
    • Hair length
    • Blood type

  16. Which condition is required when measuring basal metabolic rate accurately?

    • After eating
    • Heavy exercise
    • During sprinting
    • Complete rest

  17. What happens to total energy requirements when physical activity level increases?

    • Total energy stops
    • Total energy increases
    • Total energy decreases
    • BMR becomes zero

  18. A person has a BMR of 1,200 kcal and a PAL of 1.8. What is their estimated daily energy need?

    • 1,200 kcal
    • 2,160 kcal

  19. What is the physical activity level used as in dietary calculations?

    • A protein ratio
    • A weight limit
    • A fixed unit
    • A multiplier

  20. Why does a sedentary desk worker have a lower physical activity level than a builder?

    • Greater daily sleep
    • More heavy lifting
    • Higher muscle mass
    • Less daily movement
