What is the correct formula for Body Mass Index (BMI)?
Weight (kg) ÷ [height (m)]²
Weight (kg) ÷ height (m)
Weight (kg) × height (m)
Height (m) ÷ weight (kg)
Which best describes Basal Metabolic Rate (BMR)?
Rate at which the body uses energy at complete rest

Calories burned when digesting a large meal
Physical Activity Level (PAL) is primarily used to express what?
The intensity of a single workout
The amount of energy a person uses for daily tasks
The number of steps taken per day
The speed of heart rate increase during exercise
Which formula estimates total daily energy expenditure?
BMI × PAL
BMR × PAL
BMI + BMR
BMR ÷ BMI

Weight gain
Lower BMR
No weight change
Weight loss

Total daily energy expenditure is calculated by which relationship?
BMR divided by PAL
BMR multiplied by PAL
PAL plus dietary energy
PAL minus BMR
Which scenario best illustrates weight gain in energy balance?
Energy out equals zero energy in
Energy in equals energy out
Energy out greater than energy in
Energy in greater than energy out
Which health risk is more likely with obesity?
Osteoporosis risk increases
Heart failure risk decreases
Type 2 diabetes risk increases
Iron-deficiency risk increases
Which health problem is linked with being underweight?
Gall stones and joint pain
High blood pressure and stroke
Type 2 diabetes and colon cancer
Low bone mass and fractures
Which statement about physical activity benefits is accurate?
Eliminates all obesity risk instantly
Improves heart health and strength
Replaces need for balanced diet
Decreases muscle and bone mass
A food label shows 10 g fat, 5 g protein, and 20 g carbohydrate. Which option best estimates total energy in kilojoules?
10×29 + 5×17 + 20×16
10×37 + 5×17 + 20×16
10×37 + 5×29 + 20×17
