About bodyfatpercentage.co
We built this to be the one place people can find everything they need to understand, calculate, and improve their body fat percentage.
Our Mission
Body fat percentage is one of the most misunderstood numbers in fitness. Some sites oversimplify it, others bury the science in jargon, and most try to sell you something along the way. We wanted to fix that.
Our goal is to create a free, evidence-based hub that answers every question someone might have about body fat percentage. Whether you want to lose weight, compete, get your abs to show, prepare for a body composition scan, or just understand what 15% body fat really means, we want this site to be the first place you look and the only place you need.

Our Approach
We believe fitness content should be science-based, specific, and practical. Every number on this site comes from established research or official frameworks:
- American Council on Exercise (ACE) — body fat classification system used by fitness professionals worldwide.
- Jackson and Pollock (1978) — ideal body fat by age research, still the standard reference for age-based targets.
- Hodgdon and Beckett (1984) — the U.S. Navy circumference method used by all branches of the U.S. military.
- Deurenberg et al. — BMI-to-body-fat estimation formula.
When we make claims, we tie them to data. When we recommend rates of fat loss or protein intake, we reference peer-reviewed research. When the science is uncertain, we say so rather than making things up.
Editorial Standards
- All numbers and ranges are sourced from peer-reviewed research or established fitness organizations.
- Calculations use the same formulas as the U.S. military and major fitness certification bodies.
- Content is updated when new research emerges or standards change.
- We track our own numbers and test the methods we recommend.
