BBasal Metabolic Rate (BMR) Calculator

BMR Calculator – Quick Cheat Sheet

• BMR ≈ calories burned at rest over 24h.
• Recommended formula: Mifflin–St Jeor (MSJ):
  Male: 10×kg + 6.25×cm − 5×age + 5 · Female: 10×kg + 6.25×cm − 5×age − 161
• Alternate: Harris–Benedict (Revised 1984):
  Male: 88.362 + 13.397×kg + 4.799×cm − 5.677×age · Female: 447.593 + 9.247×kg + 3.098×cm − 4.330×age
• Units: Use Metric (kg, cm) or Imperial (lb, in). Imperial is converted to metric internally.
• Scope: This page computes BMR only (not TDEE or macros).
• Validation: Age 1–120; realistic height/weight checks after conversion.
