Find out the number calories that you may burn while not doing any activity with the BMR calculator. With that, get an instant estimations for your daily caloric needs depending upon the activity level you select.

You BMR decreases with the passing age. So using our basal metabolic rate calculator will certainly assist you to know the calories that are sufficient to keep your body major organs active even if you are in bed all the day long.

Our metabolism calculator requires necessary variables that actually affects and helsp to estimate your BMR calories. These include:

**Inputs:**

- Enter you age & select your gender
- Now enter your height & weight calculations
- At last, select your activity level from the list
- Tap
**Calculate**

**Output:**

- Your BMR Calories
- Calories that you need to eat daily to stay alive
- Moreover, you get a detailed chart containing your BMR & daily calorie needs for all possible activity levels (The calculations are done using the most authentic & scientifically proven BMR equations)

You must be thinking what is basal metabolic rate exactly!

**“It is the consumption of calories by the body at zero activity level”**

In other words, this is the amount of energy you need for your healthy survival. And if your body won’t get this minimum amount of calories, basal metabolism will decline, and you will start feeling tired with no energy to do anything.

So it is important for every person to calculate BMR with the ease of our efficient basal metabolic rate calculator.

Our advanced BMR calculator utilises the following equations to calcualte BMR calories:

Males | Females |
---|---|

BMR = 66.4730 + (13.7516 x Weight [kg]) + (5.0033 x Height [cm]) – (6.7550 x Age) | BMR = 655.0955 + (9.5634 x Weight [kg]) + (1.8496 x Height [cm]) – (4.6756 x Age) |

Males | Females |
---|---|

BMR = 88.362 + (13.397 x Weight [kg]) + (4.799 x Height [cm]) – (5.677 x Age) | BMR = 447.593 + (9.247 x Weight [kg]) + (3.098 x Height [cm]) – (4.33 x Age) |

Males | Females |
---|---|

BMR = (9.99 x Weight [kg]) + (6.25 x Height [cm]) – (4.92 x Age) + 5 | BMR = (9.99 x Weight [kg]) + (6.25 x Height [cm]) – (4.92 x Age) – 161 |

Males | |
---|---|

Age | Formula |

0-3 | 59.512 x Weight [kg] – 30.4 |

3-10 | 22.706 x Weight [kg] + 504.3 |

10-18 | 17.686 x Weight [kg] + 658.2 |

18-30 | 15.057 x Weight [kg] + 692.2 |

30-60 | 11.472 x Weight [kg] + 873.1 |

60+ | 11.711 x Weight [kg] + 587.7 |

Females | |
---|---|

Age | Formula |

0-3 | 58.317 x Weight [kg] – 31.1 |

3-10 | 20.315 x Weight [kg] + 485.9 |

10-18 | 13.384 x Weight [kg] + 692.6 |

18-30 | 14.818 x Weight [kg] + 486.6 |

30-60 | 8.126 x Weight [kg] + 845.6 |

60+ | 9.082 x Weight [kg] + 658.5 |

You must know how many calories you need to keep your major organs function properly while involved in certain activity. And this is where our BMR calculator multiples your BMR calories with activity level so that you could get instant idea of this. If your goal comes up with the manual calculations, stick to the following table:

Activity Level | Description | Formula |
---|---|---|

Low | You get little to no exercise | Calories Burned a Day = BMR x 1.2 |

Light | You exercise lightly (1-3 days per week) | Calories Burned a Day = BMR x 1.375 |

Moderate | You exercise moderately (3-5 days per week) | Calories Burned a Day = BMR x 1.55 |

High | You exercise heavily (6-7 days per week) | Calories Burned a Day = BMR x 1.725 |

Very High | You exercise very heavily (i.e. 2x per day, extra heavy workouts) | Calories Burned a Day = BMR x 1.9 |

Suppose Asad is 33 years old and weighs about 80 kg. How to calculate basal metabolic rate calories if his height is about 6ft?

Using the most authentic Mifflin-St Jeor:

BMR = (9.99 x Weight [kg]) + (6.25 x Height [cm]) – (4.92 x Age) + 5

BMR = (9.99 x 80) + (6.25 x 182.88) – (4.92 x 33) + 5

BMR = 799.2 + 1143 – 162.36 + 5

BMR = 2,109.56

Which are the required calories Asad may need to stay alive. You can also verify these calories with this advanced BMR calculator that takes instants to estimate basal metabolic calories.

Following factors contribute to any changes in your BMR:

**Age:**

Age is directly used in BMR formula, and BMR is inversely proportional to age, i.e. higher age, lower the BMR will be.

**Gender:**

It is another factor that decides your BMR while calculating BMR. Men are normally more muscular mass, so their BMR is normally higher than the women.

**Daily Activity:**

It is the factor that affects BMR figures. If you are active and exercise daily, your BMR will be high & vice versa.

**Body Size:**

Your BMR increases as height, weight and even the surface area increase.

**Body Composition:**

If the lean muscle mass increases, then the metabolic rate also increases. Also, the fat tissue has a lower metabolic activity than the muscle tissue.

**Climate and Body Temperature:**

The people who live in tropical climates areas generally have 5-20 percent higher BMR than individuals who live in more temperature areas as it takes energy to keep the body cool. Remember that exercise/physical activity that performed in hot weather also imposes an additional metabolic load.

**Hormonal Levels:**

Thyroxine (T4) is the key hormone that has a significant effect upon BMR. Hypothyroidism is a condition that is relatively common, especially in female near or after menopause.

**Health:**

Any illness, fever, or injury can increase resting metabolic rate (RMR) two-fold.

Normally, men have a BMR of about 1,600-1,800 kCals a day and when it comes to women; they have a BMR of 1,550 kCals a day. But remember that this is variable.

It is best to use the above BMR calculator to track your BMR!

On average, the BMR for an adult person is about **1766 Kcal/day**.

An individual with higher lean body mass (LBM) will enjoy a higher BMR than someone at the same weight with a higher percentage of fat and even also naturally burn more calories.

Any amount that is less than your normal total daily energy expenditure (TDEE) may cause to lose excess flab, it just based on how quickly you to see outcomes.

Metabolic meals are a Missouri-based meal delivery service that assists to take the stress out of weight loss and maintenance.

The service offers a rich menu of chef-prepared meals that are prepared with the fine quality and freshest ingredients, such meals helps to shed extra pounds gradually while boosting your health at the same time.

The calculation that you will get through the above BMR calculator is just an estimation and just taken into account for educational purposes, for a further query you ought to consult with MEDICAL EXPERTS!
