What is the formula to determine energy balance?
What is the formula to determine energy balance?
- Energy Balance= Energy In x Energy Out
- Energy Balance = Energy Out + Weight
- Energy Balance= Energy Out - Weight Change
- Energy Balance=Energy In - Energy Out (correct)

Basal Metabolic Rate (BMR)
Basal Metabolic Rate (BMR)
The amount of energy (calories) used by the body for basic functions like breathing, sleeping, and maintaining body temperature.
Digestive Energy Expenditure
Digestive Energy Expenditure
The energy (calories) used for digesting and absorbing food.
Physical Activity Energy Expenditure
Physical Activity Energy Expenditure

Study Notes
Energy Balance Explained
- Energy is used for all bodily functions, from breathing to playing sports. Different activities use varying amounts of energy.
- "Energy in" refers to the calories consumed from food and drinks. "Energy out" refers to calories burned through activity.
- Energy balance is calculated as: Energy In – Energy Out.
- Positive Energy Balance: Consuming more calories than burned. Leads to weight gain, primarily from fat.
- Negative Energy Balance: Consuming fewer calories than burned. Leads to weight loss, affecting both fat and muscle if exercise is not managed properly.
- Neutral Energy Balance: Calorie intake equals calorie expenditure. Maintains stable weight.
Daily Energy Requirements
- Basal Metabolic Rate (BMR): Accounts for 60-70% of daily energy needs. Driven by vital organ function.
- Digestion and Absorption: Consumes 10% of daily energy.
- Physical Activity: Accounts for 20-30% of daily energy needs.
- The average daily energy requirement for women is roughly 2000 calories, and for men approximately 2500 calories. This varies based on individual factors.
Factors Influencing Energy Balance
- Individual Factors: Genes, gender, age, lifestyle.
- Activity Level: Frequency and intensity of physical activity significantly influence energy expenditure.
- Diet Quality and Quantity: The type and amount of food consumed directly affects energy intake.
- Basal Metabolic Rate (BMR): The number of calories burned while at rest, influenced by factors like muscle mass.
- Body Composition: Muscle, fat, and bone influence the body's metabolic rate.
- Genetics: Play a role in determining basal metabolic rate and how the body processes food.
