Energy Expenditure

What percentage of daily calories burned is attributed to Basal Metabolic Rate (BMR)?

• 10% - 25%

• 25% - 50%

• 50% - 75%

• 75% - 90%

Which factor does NOT affect Basal Metabolic Rate (BMR)?

• Muscle mass

• Gender

• Weather conditions

• Age

What is the primary difference between Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR)?

• BMR is measured in the morning after fasting, while RMR is measured in the afternoon after eating

• RMR is always lower than BMR

• BMR includes light activities such as walking, while RMR does not

• BMR includes light activities such as walking, while RMR does not

What is the Thermic Effect of Food (TEF)?

• The energy required to sustain vital body functions

• The calories burned through physical activity

• The energy required for digestion, absorption, and metabolism of food

• The number of calories needed to maintain body temperature in cold weather

Which macronutrient has the highest thermic effect?

• Carbohydrates

• Proteins

• Fats

• Water

What does Resting Daily Energy Expenditure (RDEE) measure?

• The energy needed for physical activities

• The energy required to sustain essential functions while at rest

• The number of calories burned during exercise

• The effect of diet on metabolism

Which equation is considered more accurate for estimating Basal Metabolic Rate (BMR) in modern populations?

• Harris-Benedict Equation

• Mifflin-St Jeor Equation

• Cunningham Equation

• Body Mass Index (BMI)

What type of exercise increases Resting Daily Energy Expenditure (RDEE) by enhancing muscle activity?

• Yoga

• Walking

• Strength training

• Stretching

Which macronutrient has the highest Thermic Effect of Food (TEF)?

• Carbohydrates

• Fats

• Proteins

• Vitamins

Why does cold exposure increase energy expenditure?

• It reduces oxygen consumption

• It activates brown fat and induces shivering

• It slows down metabolism

• It increases fat storage
