1 What does Basal Metabolic Rate (BMR) represent?

A The energy required at complete rest to keep vital organs functioning
B The energy burned strictly during high-intensity exercise
C The total calories burned over an entire week
D The energy required solely for digesting complex carbohydrates

2 Which component accounts for the largest portion of daily energy expenditure?

A Thermic Effect of Food (TEF)
B Structured exercise
C Basal Metabolic Rate (BMR)
D Non-exercise activity thermogenesis (NEAT)

3 What is the Thermic Effect of Food (TEF)?

A Energy required by the body to digest, absorb, and process food
B Calories burned while performing cardio exercises
C Resting heart rate measured during sleep
D Heat produced by muscle contraction during strength training

4 What happens to body weight during a state of energy equilibrium?

A Rapid weight loss occurs
B Body weight remains stable
C Fat storage increases significantly
D Muscle mass decreases rapidly

5 What occurs during a positive energy balance (caloric surplus)?

A Energy intake is less than energy expenditure
B Body weight decreases
C Energy intake exceeds expenditure, leading to weight gain
D The body burns fat reserves for fuel

6 What is the primary outcome of a negative energy balance (caloric deficit)?

A Weight loss as the body uses stored energy
B Weight gain from increased fat storage
C Complete shutdown of the basal metabolic rate
D Immediate loss of essential organ function

7 According to the 3-3-3 rule for weight loss, how many meals should be eaten per day?

A 1 meal
B 3 meals
C 6 meals
D 5 meals

8 Which three food components should be included in each meal under the 3-3-3 framework?

A Refined sugars, saturated fats, and alcohol
B Proteins, healthy fats, and fiber-rich carbohydrates
C Dairy, simple sugars, and fruit juice
D Processed meats, white flour, and sodium

9 What is the effect of consuming refined carbohydrates on blood glucose levels?

A Slow and steady release of energy
B Rapid spike in blood glucose levels
C Immediate lowering of blood sugar levels
D No effect on blood glucose levels

10 Which combination of nutrients provides steady blood sugar and sustained energy?

A White flour and added sugar
B Fruit juice and candy
C Complex carbohydrates, fiber, lean proteins, and healthy fats
D Soda and refined pastries

11 Where is excess energy stored in the body during a caloric surplus?

A As water weight only
B As fat tissue, glycogen, and protein
C As pure blood glucose
D As bone density

12 What two components make up total daily physical activity energy expenditure (PAE)?

A Structured exercise and non-exercise activity
B Digesting food and breathing
C Basal metabolic rate and resting heart rate
D Sleeping and sitting
