The scientific term for body fat is “adipose tissue.” Far from being inert, adipose tissue plays several vital roles in your body's health and function.
The primary purpose is to store lipids (fats) from which the body derives energy during periods of need, acting as your body's natural energy reserve.
Adipose tissue secretes important hormones that influence metabolism, appetite, and other bodily functions, playing a crucial role in hormonal balance.
Body fat provides cushioning for organs and helps insulate the body, protecting vital organs and maintaining body temperature.
Body fat can be broadly categorized into two types, each serving different functions for your health.
The minimum fat necessary for basic health
This is the minimum amount of fat necessary for basic physical and physiological health. It's found in major organs, muscles, bone marrow, and the central nervous system.
*Women have higher essential fat due to childbearing and hormonal functions
Fat that accumulates beyond essential levels
This is the fat that accumulates in adipose tissue beyond essential levels. It includes both subcutaneous and visceral fat.
Found just beneath the skin (dermis)
Located deeper within the abdominal cavity, surrounding vital organs
Knowing your body fat percentage can help you understand your health status. Here are widely recognized categorizations.
| Description | 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%+ |
| Age | Women (%) | Men (%) |
|---|---|---|
| 20 | 17.7% | 8.5% |
| 25 | 18.4% | 10.5% |
| 30 | 19.3% | 12.7% |
| 35 | 21.5% | 13.7% |
| 40 | 22.2% | 15.3% |
| 45 | 22.9% | 16.4% |
| 50 | 25.2% | 18.9% |
| 55 | 26.3% | 20.9% |
Generally: A healthy body fat range for men is typically 8-19%, while the healthy range for women is 21-33%.
While excess body fat is a common concern, having insufficient body fat can also lead to negative health consequences.
Being “overweight” (as determined by BMI) doesn't necessarily mean having excess body fat. Body weight comprises multiple factors:
Example: Athletes and bodybuilders may be classified as overweight by BMI but have very healthy or low body fat percentages due to high muscle mass.
Several methods can estimate body fat percentage. Our calculator uses the U.S. Navy method, one of the most accessible and reliable estimation techniques.
Excess body fat, leading to overweight and obesity, is a major global health concern with serious implications.
The World Health Organization classifies obesity as a leading preventable cause of death worldwide.
Excess abdominal fat can disrupt normal hormone balance and function.
Visceral fat releases cytokines that increase cardiovascular disease risk.
Higher LDL (“bad”) and lower HDL (“good”) cholesterol levels.
Cells respond improperly to insulin, potentially leading to Type 2 diabetes.
While formula-based calculations provide useful estimates, clinical methods offer more precise measurements.
Uses electrical current to estimate body composition
Measures body density through underwater weighing
X-ray technology for precise body composition analysis
Uses air displacement to measure body volume
Understanding your body fat percentage is a valuable step towards managing your overall health and wellness. While these calculations provide useful estimates, they should be considered as part of a broader health assessment.
