  • Gender: Men typically have higher BMR due to more muscle mass
  • Genetics: Some people inherit a faster or slower metabolism
  • Hormones: Thyroid hormones significantly influence metabolic rate

Why BMR Matters

Knowing your BMR helps you determine your daily calorie needs for weight maintenance, loss, or gain. To maintain weight, eat calories equal to your BMR multiplied by your activity level.
