⚙️ How BM1 Is Calculated

🧮 Step-by-Step

  1. BMI = weight(kg) / height(m)<sup>2</sup>
  2. BM1 Score =
    BMI × gender multiplier × age adjustment × activity level
    • Gender Multiplier: 1.1 (male), 1.0 (female)
    • Age Adjustment: Slight decrease after age 25
    • Activity Level: Ranges from 1.2 to 1.9
  3. Body Fat %:
    • Males: (1.20 × BMI) + (0.23 × Age) – 16.2
    • Females: (1.20 × BMI) + (0.23 × Age) – 5.4
  4. BMR (Basal Metabolic Rate):
    • Males: 88.362 + 13.397 × weight(kg) + 4.799 × height(cm) – 5.677 × age
    • Females: 447.593 + 9.247 × weight(kg) + 3.098 × height(cm) – 4.330 × age
  5. Daily Calories = BMR × Activity Level

🧠 Tips for Accurate Results

  • Use correct units (lbs ↔ kg, ft/in ↔ cm)
  • Always fill in age, gender, and activity for proper calculations
  • BM1 is more detailed than BMI—use it to personalize your goals
  • Combine this tool with fitness tracking apps or routines
