Practical Example of Body Fat Calculation

Let’s understand how the tool works with a real example:

Input Values:

• Gender: Male
• Age: 30 years
• Weight: 75 kg
• Height: 175 cm

Step 1: BMI Calculation

BMI = weight / (height in meters)²
= 75 / (1.75 × 1.75)
= 24.5

Step 2: Body Fat Percentage

Using the estimation formula for males:
Body Fat ≈ 1.20 × BMI + 0.23 × Age − 16.2
= 1.20 × 24.5 + 0.23 × 30 − 16.2
= 18.9% (approx.)

Step 3: Fat Mass

Fat Mass = 75 × 18.9%
= 14.2 kg

Step 4: Lean Body Mass

Lean Mass = 75 − 14.2
= 60.8 kg

Step 5: Fitness Level

Based on results, this falls into the:

• Fit category

Health Tip:

Maintain consistency in exercise and balanced nutrition.
