Key Facts: BMR Calculator for Women

  • Average female BMR: 1,200–1,400 calories/day
  • BMR fluctuates 5-10% across the menstrual cycle
  • Women have ~10% lower BMR than men of the same weight
  • Strength training is the #1 way to boost resting metabolism

Special Considerations for Women

  • Never go below 1,200 calories without medical supervision
  • Luteal phase (post-ovulation) increases BMR by ~100-300 calories
  • Iron deficiency (common in women) can lower metabolic rate
  • Hormonal birth control may slightly affect water retention but not true BMR
