This uses the Mifflin-St Jeor equation.

BMR vs. TDEE

BMR estimates the energy your body uses at rest. TDEE adds activity and daily movement, which makes it more useful for planning intake.

Why BMR matters in treatment

BMR can help frame expectations, but it does not diagnose metabolism. A medical intake should still account for medications, labs, history, and symptoms.

What to do with the result

Save the number, compare it with your goals, and bring it into the Caliber intake. A clinician-reviewed plan can account for medical history, medications, tolerability, and whether GLP-1 therapy is appropriate.
