Study Notes
Estimated Energy Requirement (EER)
- EER indicates average dietary energy required to maintain energy balance in a healthy individual, factoring in gender, age, weight, height, and physical activity level.
- Takes into account energy needed for growth, pregnancy, and lactation (e.g., milk production).
Body Weight Criteria
- Stable body weight within the healthy range is essential for energy balance.
Basal Metabolic Rate (BMR)
- BMR refers to the minimum energy expenditure necessary for sustaining life functions at rest.
- Measured under conditions of rest, fasting, immobility, thermoneutrality, and mental relaxation, typically while supine.
Energy Expenditure Metrics
- BMR is expressed as Basal Energy Expenditure (BEE), in kilocalories over a 24-hour period.
- Total Energy Expenditure (TEE) represents the average energy spent in a typical day.
Energy Balance and Physical Activity Level (PAL)
- PAL is the ratio of TEE to BEE, reflecting overall activity levels.
- In adult men and non-pregnant, non-lactating women, TEE can be calculated as BEE multiplied by PAL.
Recommended Physical Activity Levels
- A minimum of 30 minutes of moderate-intensity physical activity (PA) is recommended most days for basic health benefits.
- To avoid weight gain and gain additional health benefits, 60 minutes of moderate-intensity PA, such as walking at 4 mph, is advised.
Active Lifestyle
- An active lifestyle corresponds to a total energy expenditure greater than 1.6-1.7 times the resting energy expenditure (REE).
- Maintaining this lifestyle helps keep body weight in the ideal range and reduces cardiovascular disease (CVD) risk.
Physical Activity Coefficients for EER Calculation (Females)
- PAL conversion to physical activity coefficients:
- PA = 1.0 for PAL > 1.0
- PA = 1.12 for PAL around 1.3
- PA = 1.27 for PAL around 1.6
- PA = 1.45 for PAL around 1.9
