Body fat percentage represents how much of your total body weight comes from fat. Unlike body weight alone, this measurement gives a clearer picture of overall health, fitness level, and disease risk.
Body fat, scientifically known as adipose tissue, plays an essential role in energy storage, hormone production, insulation, and organ protection. It includes both essential fat required for survival and storage fat.
Essential fat supports basic physiological functions, while storage fat accumulates under the skin and around internal organs. Excess storage fat, especially visceral fat, increases health risks.
| Category | Women | Men |
|---|---|---|
| Essential Fat | 10–13% | 2–5% |
| Athletes | 14–20% | 6–13% |
| Fitness | 21–24% | 14–17% |
| Average | 25–31% | 18–24% |
| Obese | 32%+ | 25%+ |
High body fat—particularly abdominal fat—is linked to cardiovascular disease, type 2 diabetes, high cholesterol, hormonal imbalance, joint issues, sleep apnea, and reduced life expectancy.
Visceral fat is metabolically active and interferes with insulin sensitivity, cholesterol levels, and inflammatory processes within the body.
This calculator uses the U.S. Navy Method, developed by the Naval Health Research Center. It estimates body fat using simple body measurements such as waist, neck, height, and hip circumference for women.
While not a medical diagnosis, this method provides a reliable estimate for most people.
Yes. Body fat percentage provides more detailed insight into body composition, while BMI does not distinguish fat from muscle.
Extremely low body fat can disrupt hormones, immune function, and reproductive health. Medical guidance is recommended.
Measuring every 2–4 weeks is ideal for tracking trends without daily fluctuations.
