Understand the concept

BMR (Basal Metabolic Rate) is an estimate of how many calories your body uses per day at rest, maintaining vital functions such as breathing, circulation and body temperature.

It is different from your total daily expenditure (TDEE): the total includes activities, work, training and even the thermic effect of food. TMB is just the “base”.

Practical example: if your estimated BMR is 1,600 kcal/day and you have a moderately active routine, your total expenditure could be close to 1,600 × 1.55 ≈ 2,480 kcal/day (typical factor). This account is an approximation for planning.

The BMR is useful for establishing a starting point for caloric intake (maintenance, deficit or surplus) and for comparing scenarios.

Limitations: formulas are population averages; body composition, hormones, sleep, stress, medication and diet history can change actual spending. Use as a reference and adjust with professional guidance when necessary.

How to use this tool

  1. Enter age, sex, weight and height.
  2. Click calculate to see BMR (kcal/day).
  3. Use BMR as a base and apply separate activity factors.

FAQ

What is BMR?

The minimum energy your body spends at rest for vital functions.

Why does my device show a different value?

Devices use sensors and proprietary models; our BMR follows standard formulas.

Can I use BMR to lose weight?

Use as a reference and adjust with activity and professional guidance.

Technical notes

Base técnica

Fórmula: TMB (homens) = 10×Peso + 6,25×Altura − 5×Idade + 5; TMB (mulheres) = 10×Peso + 6,25×Altura − 5×Idade − 161. Unidade e escopo: estimamos a Taxa Metabólica Basal (TMB) com base em peso, altura, idade e sexo usando Mifflin–St Jeor.
