  • Body Fat Percentage: The estimated proportion of fat in your body based on BMI and age.
  • Daily Calorie Needs: The number of calories you should consume daily to maintain your current weight considering your activity level.

By calculating these metrics, you can assess whether your weight is in a healthy range, track your progress, and adjust your diet or exercise routines accordingly.

How the Calculator Works

The Body Figure Calculator uses scientifically recognized formulas:

  • BMI Calculation:
    BMI = Weight / (Height × Height) in metric units. It indicates whether your weight is underweight, normal, overweight, or obese.
  • Body Fat Percentage (Estimate):
    • Male: (1.20 × BMI) + (0.23 × Age) – 16.2
    • Female: (1.20 × BMI) + (0.23 × Age) – 5.4
  • Daily Calorie Needs (Mifflin-St Jeor Equation):
    • Male BMR: 10 × Weight + 6.25 × Height – 5 × Age + 5
    • Female BMR: 10 × Weight + 6.25 × Height – 5 × Age – 161
      Daily calories = BMR × Activity Factor

This combination of formulas gives you an accurate reflection of your body metrics and caloric requirements.

Example Calculation

Scenario:

  • Weight: 70 kg
  • Height: 175 cm
  • Age: 28
  • Gender: Female
  • Activity Level: Moderately Active

Results:

  • BMI: 22.86 (Normal weight)
  • Body Fat Percentage: 22.01%
  • Daily Calorie Needs: 2,200 kcal

Analysis:
These results indicate that the user is in a healthy weight range. The body fat percentage is within the recommended range for females, and 2,200 calories per day are needed to maintain her current weight at a moderate activity level. This information helps plan workouts and nutrition effectively.

Tips for Using the Body Figure Calculator Effectively
