What is Body Fat Percentage? How to Calculate It and Healthy Ranges

Do you know your body fat percentage? For those who want to lose weight or stay fit, BMI (Body Mass Index) alone is not enough. The true health indicator is the amount of fat in your body. In this guide, you’ll learn what your body fat percentage means, how it’s calculated, and the healthy ranges for men and women.

What is Body Fat Percentage?

Body fat percentage is the proportion of your total body mass that is made up of fat. There are two main types of fat:

• Essential Fat: Required for vital functions and reproduction. Ranges from 10–13% in women and 2–5% in men.

• Storage Fat: Stored as energy reserves; excess amounts can pose health risks.

Fat is not inherently “bad.” It protects your organs, is essential for hormone production, and regulates body temperature. However, excessive fat is directly linked to heart disease, diabetes, and other chronic conditions.

How is Body Fat Percentage Calculated?

The most common and practical method is BMI-based estimation formulas. We use the Deurenberg formula, which has been tested on over 6,500 people and provides reliable results with a 4.66% margin of error.

📐 Formula Used:

$$\text{Body Fat (\%)} = (1.20 \times \text{BMI}) + (0.23 \times \text{Age}) – (10.8 \times \text{Gender}) – 5.4$$

• Gender: Male = 0, Female = 1

• BMI: Weight (kg) ÷ Height² (m²)

⚠️ Note: This method may be inaccurate for athletes or highly muscular individuals since muscle is heavier than fat, which can inflate BMI.

Healthy Body Fat Percentage Ranges

Based on American Council on Exercise (ACE) data:

For Women

For Men

📌 Important: As age increases, metabolism slows, so healthy fat percentages may be slightly higher. Values above 30% for women and 25% for men pose health risks.

How to Reduce Body Fat Correctly

Losing weight ≠ losing fat. The goal is to reduce fat while maintaining muscle mass. Effective strategies include:

• Balanced Diet: Avoid processed foods and increase protein intake.

• Cardio + Strength Training: Running alone is not enough; resistance training preserves muscle.

• Adequate Hydration: Water is crucial for fat metabolism.

• Sleep & Stress Management: Lack of sleep and high cortisol levels increase fat storage.

• Regular Tracking: Monitor progress monthly rather than weekly.

❌ Avoid: “Magic diets” or extreme calorie restriction, which lead to muscle loss and slower metabolism.

Body Fat Measurement Methods

At home, the most practical methods are reliable calculators or BIA scales.

FAQ

Q: Is my body fat normal?

Q: How much fat can I lose per month?
A: Healthy average: 1–3% body fat reduction per month.

Q: Which is more important, BMI or body fat percentage?
A: Body fat percentage is more accurate because it accounts for muscle and bone mass, unlike BMI.
