What Is BMR? Understanding Basal Metabolic Rate and Energy Expenditure

Updated: Jun 20, 2023

Understanding Basal Metabolic Rate (BMR) & Energy Expenditure (TDEE): A Key to Health and Fitness

Understanding your body's energy requirements is a crucial step towards achieving your health and fitness goals. One of the most important factors in this equation is your Basal Metabolic Rate (BMR). This article will delve into the intricacies of BMR, its impact on your total daily energy expenditure, and how you can manipulate these factors to improve your overall health and fitness.




What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is a measure of the minimum amount of energy, usually expressed in calories, that your body requires to sustain basic physiological processes while at rest. These processes include breathing, circulating blood, and maintaining body temperature, among others.

BMR is influenced by several factors, including body composition, gender, and age. For instance, individuals with more muscle mass tend to have higher BMRs than those with less muscle mass at the same weight. This is because muscle mass requires more energy to maintain than fat does.

Moreover, males and younger individuals generally have higher BMRs than females and older individuals, largely due to differences in muscle mass. As we age, our muscle mass decreases, which in turn reduces our BMR.

The Bigger Picture: Total Daily Energy Expenditure (TDEE)

While BMR accounts for a significant portion (around 60 percent) of our total daily energy expenditure, it's only a part of the picture. The total amount of energy your body expends in a day, also known as Total Daily Energy Expenditure (TDEE), is influenced by several factors, including:

  1. Gender

  2. Age

  3. Height

  4. Weight

  5. Non-exercise activity

  6. Exercise activity

  7. Thermic effect of food

Physical activity, such as exercise or simply moving more during the day, significantly influences your TDEE. A person who exercises or moves more will have a higher TDEE than someone who is less active.

Additionally, the thermic effect of food, which refers to the energy expended during digestion and absorption of food, also contributes to your TDEE.

By understanding and manipulating these factors, you can influence your total daily energy expenditure and, ultimately, your health and fitness outcomes.
