Understanding Your Basal Metabolic Rate (BMR) in Quebec: An Essential Indicator

Understanding Your Basal Metabolic Rate (BMR) in Quebec: An Essential Indicator

November 10, 2025 · By Metrolex

Quick Summary — Quebec: The Basal Metabolic Rate (BMR) represents the minimum energy your body needs to function at rest. In Quebec, where climate, seasons, and lifestyle habits vary greatly, knowing your BMR is essential for better managing your energy, weight, and overall health. Thanks to BIA technology, Metrolex scales provide an accurate, personalized BMR measurement based on your actual body composition.

What Is Basal Metabolic Rate?

The BMR is the amount of energy (calories) your body uses at rest to maintain vital functions:

  • breathing
  • blood circulation
  • temperature regulation
  • organ function
  • cellular maintenance

Common theoretical formula: BMR = 370 + (21.6 × lean body mass in kg)

This formula (Cunningham) is only an estimate. Metrolex uses real data measured by BIA for greater accuracy.

What Factors Affect BMR?

  • age
  • sex
  • weight
  • muscle mass (the most important factor)
  • genetics
  • hydration
  • hormones

The more muscle mass you have, the higher your BMR, even at rest.

Limitations of Traditional Formulas

  • they do not account for actual muscle mass
  • they ignore fat distribution
  • they do not measure hydration
  • they do not reflect typical seasonal variations in Quebec

Two people of the same age, height, and weight can have completely different BMRs depending on their body composition.

Why Metrolex Goes Beyond Theoretical Calculations

Metrolex scales use BIA to calculate an accurate BMR based on real body composition. They measure:

  • muscle mass
  • fat mass
  • body water
  • visceral fat
  • metabolic age
  • basal metabolic rate (BMR)
  • total energy expenditure
  • … and over 56 other indicators

FAQ – BMR: Frequently Asked Questions

Why is my BMR low?

A low BMR is often linked to low muscle mass. Hydration, age, and certain hormones also play a role.

How can I increase my BMR?

The most effective way is to increase muscle mass. Regular physical activity and optimal hydration contribute to this.

Why is Metrolex more accurate than online calculators?

Because Metrolex measures actual body composition using BIA rather than relying only on your weight and height.

BMR, RMR, and total energy expenditure: what's the difference?

BMR (Basal Metabolic Rate) refers to the calories burned at rest to maintain vital functions. RMR (Resting Metabolic Rate) is sometimes used interchangeably. Total energy expenditure includes BMR plus calories burned through physical activity and digestion. In summary: BMR ≤ RMR ≤ total daily expenditure.

How does BIA improve BMR accuracy?

BIA (Bioelectrical Impedance Analysis) measures real body composition: muscle mass, fat mass, and hydration. This data allows a personalized and much more precise BMR calculation than theoretical formulas.

Does BMR change with age or season?

Yes, BMR generally decreases with age due to muscle loss. In Quebec, seasonal variations (temperature, physical activity) can also slightly influence your energy expenditure.
