What is BMR?

BMR (Basal Metabolic Rate) is the energy your body uses at rest. That means, even if you spend the whole day lying in bed doing nothing, your body still burns calories for these essential functions:

• Keeping your heartbeat going
• Operating your lungs
• Controlling body temperature
• Running the brain and nervous system
• Digestion and organ function

BMR is your body’s energy baseline. Knowing it helps you create the right diet and exercise plan.
