Calculate

# mifflin st jeor formula The Mifflin-St Jeor formula, created in the 1990s, provided an alternative and more valid estimate of RMR (3). The equations for males and females are: Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161.

## Is the Mifflin St JEOR equation accurate?

Of these equations, the Mifflin-St Jeor equation was the most reliable, predicting RMR within 10% of measured in more nonobese and obese individuals than any other equation, and it also had the narrowest error range.

## What is the Mifflin St JEOR equation used for?

The third known equation is Katch-McArdle formula, used to calculate the Resting Daily Energy Expenditure (RDEE). In our Basal Metabolic Rate Calculator, we use the Mifflin St Jeor Equation to give you the most accurate BMR score.

## What is the formula to calculate BMR?

There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively:

1. BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years])
2. BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])

## How do you calculate TDEE manually?

To calculate your approximate TDEE, simply multiply these activity factors by your BMR:

1. Sedentary (little to no exercise + work a desk job) = 1.2.
2. Lightly Active (light exercise 1-3 days / week) = 1.375.
3. Moderately Active (moderate exercise 3-5 days / week) = 1.55.
4. Very Active (heavy exercise 6-7 days / week) = 1.725.

## What is the EER formula?

EER = 1085.6 - 10.08*age (years) + PAL *(13.7* weight (kg) + 416* height (m)), where PAL = 1 if sedentary, 1.12 if low active, 1.29 if active and 1.59 if very active.

## How do I calculate my calorie needs?

To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:

1. If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.
2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.

## What does RMR stand for?

Resting metabolic rate (also called RMR) is the rate at which your body burns energy when it is at complete rest. You can calculate your RMR to see how many calories your body needs to perform basic functions like breathing and circulation.

## What is BMR vs RMR?

Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it's at rest.

## At what age do women's metabolism slow down?

It's not your imagination. As we age, our metabolism slows and the rate at which we break down food decreases by 10 percent each decade after age 20. Metabolism is the amount of energy (calories) your body uses to maintain itself.

## What is a normal 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. The rate of energy expenditure is usually lowest in the early morning.

## How do you calculate ideal body weight?

Ideal body weight is computed in men as 50 + (0.91 × [height in centimeters − 152.4]) and in women as 45.5 + (0.91 × [height in centimeters − 152.4]). A simple alternative would be to compute ideal body weight as the weight corresponding to an ideal body mass index of 22 kg/m2.

## How do I raise my BMR?
