BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure) are two key concepts in understanding how your body uses energy:

  1. BMR (Basal Metabolic Rate): This is the number of calories your body needs to perform basic functions like breathing, circulating blood, and maintaining body temperature while at rest. It represents the energy required for your body to function even if you were doing nothing all day.

  2. TDEE (Total Daily Energy Expenditure): This is the total number of calories you burn in a day, accounting for not just your BMR, but also the calories burned through physical activity, digestion, and other daily activities. TDEE is often used to determine how many calories you should consume to maintain, lose, or gain weight, depending on your activity level.

To summarize:

  • BMR is your “resting” calorie burn.
  • TDEE is your “active” calorie burn, considering everything you do throughout the day.

If you’re trying to manage your weight, understanding both is super helpful for tailoring your diet and exercise. Do you have a specific goal related to these?
