What Are BMR and TDEE?

Basal Metabolic Rate (BMR)

BMR represents the minimum amount of energy (calories) your body needs to maintain basic life functions while at complete rest.

  • Breathing and circulation
  • Cell production and regeneration
  • Brain and nerve function
  • Temperature regulation
  • Hormone regulation

Total Daily Energy Expenditure (TDEE)

TDEE is the total number of calories your body burns in a day, including your BMR plus additional energy used for:

  • Physical activity and exercise
  • Daily movements and tasks
  • Digesting and processing food
  • Non-exercise activity thermogenesis (NEAT)

How the Mifflin-St Jeor Equation Works

The Mifflin-St Jeor Equation is considered one of the most accurate formulas for calculating BMR. It takes into account several key factors:

For men:

BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

For women:

BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Why Knowing Your TDEE Is Important

Weight Management

  • Set realistic weight goals
  • Plan appropriate calorie intake
  • Create sustainable diet plans
  • Make informed food choices

Performance & Health

  • Optimize athletic performance
  • Support muscle growth
  • Maintain energy levels
  • Prevent metabolic slowdown

Remember: While these calculations provide a good starting point, individual factors such as metabolism, body composition, and specific health conditions can affect your actual caloric needs. For personalized guidance, consider creating an account to track your progress and adjust your calculations over time.
