## What affects BMR?

Your BMR will rise due to anything that raises your metabolic rate. Your **BMR** varies depending on height, weight, age, and body mass. Your gender also impacts you because it is generally accepted that men need more calories than women.

When it comes to manual calculation, there are a few equations used to calculate this BMR, and they are

- Revised Harris-Benedict Equation
- Mifflin-St Jeor Equation
- Cunningham Equation

## Different BMR equations for men and women

Revised Harris-Benedict Equation = (88.40 + 13.40 x weight in kg) + (4.80 x height in cm) – (5.68 x age in years) for men.

Revised Harris-Benedict Equation =(447.60 + 9.25 x weight in kg) + (3.10 x height in cm) – (4.33 x age) for women

#### Mifflin-St Jeor Equation

Mifflin-St Jeor Equation=(9.99 x weight in kg) + (6.25 x height in cm) – (4.92 x age in years) + 5 for men

Mifflin-St Jeor Equation=(9.99 x weight in kg) + (6.25 x height in cm) – (4.92 x age in years) – 161 for women

#### Cunningham Equation

Cunningham Equation=500 + (22 x lean body mass in kg) (for both men and women)

Among all the three Revised Harris-Benedict Equation is a common equation used to calculate BMR.

## Reading BMR values for the total needed energy is as follows

- BMR *1.2- Little or no exercise
- BMR * 1.375 – light exercise
- BMR * 1.55 – normal exercise
- BMR * 1.725 – Very active
- BMR * 1.9 – Extra active

## According to the calculation above:

- You must consume fewer calories over the long term than you expend if you want to reduce weight.
- You must eat a little bit more
**Calories**per day than you expend to gain weight. - You must consume roughly the same quantity of food as you expend over time to maintain your current weight.

## Another way to calculate BMR is just by using this simple BMR calculator

All you need to do is

Step 1: To choose the metric you want to feed, whether it is US units or metric units

Step 2: Select the gender

Step 3: Feed the age

Step 4: input the height and weight details

Step 5: Press calculate

And you will get a BMR chart on the actual number of calories that need to be consumed based on your exercise or workout schedule, based on which you can make lifestyle changes that help you reduce weight.

## How to increase BMR?

- Building muscle is the most effective technique to raise BMR. Lean muscle mass increases metabolism and burns more calories than fat. And functional training will help you gain muscle faster.
- Eating the appropriate number of calories is another technique to raise BMR that you could have inferred from the calculator.
- Try to have stress under control.

Following these three above ways improves your BMR value and use our BMR Calculator to know th values.
