Body Fat Guidelines
About Body Fat Percentage
Body fat percentage is the proportion of fat tissue in your body compared to your total body weight. It's a more accurate indicator of health and fitness than BMI alone, as it distinguishes between muscle and fat mass.
Measurement Methods
- Navy Method: Uses circumference measurements (waist, neck, hip for women)
- Skinfold Method: Uses skinfold thickness measurements at specific body sites
- BMI Estimation: Estimates body fat based on BMI, age, and gender
- DEXA Scan: Most accurate but requires specialized equipment
- Bioelectrical Impedance: Uses electrical signals (body fat scales)
Factors Affecting Body Fat
- Gender: Women naturally have higher body fat percentages
- Age: Body fat typically increases with age
- Genetics: Natural predisposition affects fat distribution
- Activity Level: Regular exercise reduces body fat
- Diet: Caloric intake affects fat storage
- Hormones: Affect fat storage and distribution
Health Implications
- Too low body fat can affect hormone production and immune function
- Optimal ranges support metabolic health and physical performance
- Excess body fat increases risk of cardiovascular disease and diabetes
- Body fat distribution matters - visceral fat is more dangerous than subcutaneous
Frequently Asked Questions
What is body fat percentage?
Body fat percentage is the proportion of fat tissue in your body compared to your total body weight. It's a better indicator of health than BMI alone.

How is body fat percentage calculated?
Body fat can be calculated using various methods including Navy method (waist/neck measurements), skinfold measurements, or estimated from BMI.
Which method is most accurate?
DEXA scan is most accurate, followed by hydrostatic weighing. Navy method and skinfold are good estimates when done correctly. BMI estimation is least accurate but convenient.
