    • Energy balance refers to the relationship between energy intake and energy expenditure
    • In a state of energy balance, energy intake equals energy expenditure
    • Order the three states of energy balance based on their outcomes
      1️⃣ Weight maintenance
      2️⃣ Weight gain
      3️⃣ Weight loss
    • An energy surplus occurs when energy intake exceeds energy expenditure
    • An energy deficit leads to weight loss
    • What is energy intake measured in?
      Calories or kilojoules
    • Carbohydrates provide an average of 4 calories per 100g
    • Proteins provide the same energy content as carbohydrates
    • How many calories does fat provide per 100g?
      9 calories
    • Fats provide 9 calories per 100g, which is equivalent to 37 kilojoules
    • Energy balance is the relationship between energy intake and expenditure
    • In positive energy balance, energy intake is less than energy expenditure
      False
    • Carbohydrates provide an average of 4 calories per 100g
    • Fats provide more than twice the energy of carbohydrates
    • What are the three components of energy expenditure?
      BMR, activity, TEF
    • Basal Metabolic Rate (BMR) accounts for 60-75% of total energy expenditure
    • The Thermic Effect of Food (TEF) accounts for 10% of total energy expenditure
    • What happens to excess energy in positive energy balance?
      Stored as fat
    • Excess energy in positive energy balance is stored primarily as fat in adipose tissue
    • Match the energy balance state with its outcomes:
      Positive ↔️ Weight gain
      Negative ↔️ Weight loss
    • Order the components of energy expenditure by their percentage of total expenditure
      1️⃣ Basal Metabolic Rate (BMR)
      2️⃣ Activity Expenditure
      3️⃣ Thermic Effect of Food (TEF)
    • Basal Metabolic Rate (BMR) is affected by age, gender, and muscle mass
    • What does the body use for energy in negative energy balance?
      Stored fat
    • In negative energy balance, energy expenditure exceeds energy intake
    • What occurs during positive energy balance?
      Energy intake exceeds expenditure
    • During positive energy balance, excess energy is stored primarily as fat
    • Weight gain is a common outcome of positive energy balance.
    • What is the key equation for positive energy balance?
      Energy Intake>Energy Expenditure=\text{Energy Intake} > \text{Energy Expenditure} =Fat Storage \text{Fat Storage}
    • In negative energy balance, the body draws upon stored fat
    • Weight loss is a common outcome of negative energy balance.
    • What is the key equation for negative energy balance?
      \text{Energy Intake} < \text{Energy Expenditure} = \text{Fat Breakdown}</latex>
    • Match the energy balance state with its outcome:
      Energy Balance ↔️ Weight maintenance
      Positive ↔️ Weight gain
      Negative ↔️ Weight loss
    • Basal Metabolic Rate (BMR) accounts for 60-75% of total energy expenditure
    • Genetics can influence a person's BMR and predisposition to weight gain or loss.
    • What does Total Daily Energy Expenditure (TDEE) represent?
      Total energy used in a day
    • Match the component of TDEE with its percentage:
      Basal Metabolic Rate (BMR) ↔️ 60-75%
      Activity Expenditure ↔️ 15-30%
      Thermic Effect of Food (TEF) ↔️ 10%
    • The TDEE calculation formula is: TDEE=\text{TDEE} =BMR+ \text{BMR} +Activity Expenditure+ \text{Activity Expenditure} +TEF \text{TEF}, where TEF stands for Thermic Effect of Food
    • Age, gender, and muscle mass are factors that affect TDEE.
    • What are the three states of energy balance?
      Energy balance, surplus, deficit
    • Energy intake is measured in calories
