BMR

Basal Metabolic Rate - the number of calories your body burns at complete rest just to stay alive. BMR represents the minimum energy your body needs to maintain vital functions like breathing, circulation, cell production, and brain function. It typically accounts for 60-75% of total daily calorie expenditure.

Understanding bmr is fundamental to achieving any body composition goal, whether that's fat loss, muscle gain, or maintenance. Without this knowledge, you're essentially guessing with your diet.

You can track bmr using Fitnit's AI nutrition scanning feature. Simply take a photo of your meal, and the app will analyze the nutritional content including calories and macro breakdown. For manual tracking, start by calculating your daily targets based on your goals and body stats.

BMR is closely connected to TDEE, Caloric Deficit, Macros. Understanding these related concepts together gives you a more complete picture of nutrition science and helps you make better decisions about your diet.
