BMR (calculated with the predictive equation in Table 5.2): 5.45 MJ/day (1 302 kcal/day). PAL (mid-point of the moderately active lifestyle in Table 5.3): 1.85. Energy requirement: 5.45 × 1.85 = 10.08 MJ/ day (2 410 kcal/day), or 10.08/55 = 183 kJ/kg/day (44 kcal/kg/day).
What is the formula for calculating EER?
EER = 389.2 – 41.2*age (years) + PAL * (15 * weight (kg) + 701.6 * height (m)) , where PAL = 1 if sedentary, 1.18 if low active, 1.35 if active, and 1.60 if very active.
How is EEE calculated?
TDEE is calculated by adding four numbers together: basal metabolic rate , thermic effect of feeding, exercise energy expenditure, and non-exercise activity thermogenesis.
What is a normal EER?
Background. Estimated Energy Requirement (EER): Estimated Energy Requirement (EER) is the average dietary energy intake that is predicted to maintain energy balance in healthy, normal weight individuals of a defined age, gender, weight, height, and level of physical activity consistent with good health.
What is the formula of total energy requirement?
| Reference Formulas | Energy (Total caloric intake/ATER) × 100 | Protein (Protein intake/Protein allowance) × 100 | Fat (Fat intake/Fat allowance) × 100 | Carbohydrates (Carbohydrate intake/Carbohydrate allowance) × 100 |

What is BMR formula?
Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
What is total energy requirement?
The total energy requirement of an individual is represented by his heat production or, in other words, his total metabolism. If food of a total caloric value equaling the heat production be taken, the normal man will remain in nutritive balance.
How much energy do I need per day?
As a guide, an average man needs around 2,500kcal (10,500kJ) a day to maintain a healthy body weight. For an average woman, that figure is around 2,000kcal (8,400kJ) a day. These values can vary depending on age, size and levels of physical activity, among other factors.
How do you calculate physical activity level?
As growth does not contribute to energy needs in adulthood, PAL can be measured or estimated from the average 24-hour TEE and BMR (i.e. PAL = TEE/BMR ). Multiplying the PAL by the BMR gives the actual energy requirements.
How do you use the Schofield equation?
| Age (years) Males Females | ≥ 60 BMR =11.711 x (wt kg) + 587.7 SEE = 164 BMR =9.082 x (wt kg) + 658.5 SEE: 108 |

What is energy needed for?
Energy is needed to perform heavy labor and exercise , but humans also use a great deal of energy while thinking and even while sleeping. For every action that requires energy, many chemical reactions take place to provide chemical energy to the systems of the body, including muscles, nerves, heart, lungs, and brain.
What is the most accurate BMR formula?
Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and, is therefore what we used in this calculator. This BMR formula is as follows: BMR (kcal / day) = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s (kcal / day) , where s is +5 for males and -161 for females.
What is a good BMR?
An average man has a BMR of around 7,100 kJ per day , while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day.
