This **TDEE calculator** determines the daily calorie intake based on the total daily energy expenditure for a period of 24 hours based on the Harris Benedict formula. You can read more on this subject below the form.

## How does this TDEE Calculator work?

This health tool estimates the daily calorie intake. TDEE is a factor defined as the Total Daily Energy Expenditure and represents the calories your body burns in a period of 24 hours.

The *TDEE calculator* is based on Harris Benedict formula multiplied by an activity level coefficient and all the information you are required to input is your height, weight, age and activity level. TDEE values can be applied to diet, exercise or simple health maintenance.

A basic TDEE calculation estimates the daily calorie in order to maintain your weight, lose or gain weight based on a plan with one or two lbs per week or 0.5 or 1 kg per week. The above application has two tabs for the two measurements systems: English with height in feet and/or inches and weight in lbs, and Metric with height in centimeters and weight in kilograms. So it can be quite easy to input your date in the measurement you prefer.

Please note that the coefficients are very subjective and they do not pretend they are 100% accurate.

Activity level | Coefficient |

Basal Metabolic Rate (BMR) | - |

No or little exercise/sedentary | 1.2000 |

Easy exercise (2-3 times/week) | 1.3751 |

Moderate exercise (4 times/week) | 1.41870 |

Active exercise (5 times/week) | 1.46251 |

Very active exercise (5 times intense/week) | 1.5500 |

Day by day exercise | 1.6376 |

Day by day intense exercise/twice daily | 1.7252 |

Daily exercise and physical activity/job | 1.9100 |

## Example of a calculation:

Let’s take for example the case of a female, aged 35 weighing 134 lbs at a height of 6ft 1’ and an exercise level characterized as easy exercise (2-3 times/week).

Result:

- To maintain your weight you will need aprox. 1,946.7 calories/day, or 8.1 kJ/day;
- To lose 1 lb per week, you will need aprox. 1,446.7 calories/day, or 6.1 kJ/day;
- To lose 2 lb per week, you will need aprox. 946.7 calories/day, or 4.0 kJ/day;
- To gain 1 lb per week, you will need aprox. 2,446.7 calories/day, or 10.2 kJ/day;
- To gain 2 lb per week, you will need aprox. 2,946.7 calories/day, or 12.3 kJ/day.

## Why use the TDEE calculation?

To check your body parameters and then you would be able to plan your daily calorie intake according to your needs.

For instance, if you would like to lose weight then you would need to adjust the TDEE calories in the terms you want to lose that weight. A word of caution in this respect would be that you are not advised to subtract more than 20-25% of the TDEE if you want to lose weight in a healthy way.

Few people are even interested in putting on weight gradually and the TDEE calculator can help with that too. Not to mention knowing exactly how many calories you should have in order to maintain your weight in time.
