Terms & Conditions
Please read these terms and conditions carefully before using ffmicalculatorreal.com. By accessing or using this website, you agree to be bound by these terms.
1. Health & Medical Disclaimer
ffmicalculatorreal.com is strictly an educational and mathematical estimation tool. The metrics provided—including Fat-Free Mass Index (FFMI), Normalized FFMI, Lean Body Mass, and projected genetic maximums—are derived from published peer-reviewed sports physiology models (specifically Kouri et al., 1995, and the US Navy Hodgdon & Beckett equations).
This website does NOT provide medical advice, clinical diagnoses, treatment plans, or dietary prescriptions. Calculations should never replace professional consultation with a licensed physician, clinical endocrinologist, sports medicine specialist, or registered dietitian.
Before undertaking strenuous progressive resistance training, extreme caloric deficits, dehydration protocols, or significant lifestyle interventions, you must seek medical clearance from a qualified healthcare professional.
2. Estimation Accuracy & Physiological Limitations
While our algorithms execute exact mathematical formulas with zero rounding distortion, all body composition assessments have inherent physiological variance:
- Hydration and Glycogen: Intracellular fluid, glycogen loading, and sodium intake impact total scale weight and lean mass estimations.
- Skeletal Frame Variations: Bone density and individual frame variations (such as wrist and ankle circumference) influence drug-free muscular potential.
- Body Fat Assessment Variance: Calipers, smart scales (BIA), and tape measurement methods typically possess an error margin of ±2% to 4% compared to clinical Dual-Energy X-ray Absorptiometry (DEXA) or 4-compartment testing.
We make no warranties or guarantees regarding individual athletic outcomes or personal health status derived from these calculations.
3. Intellectual Property & Acceptable Use
The underlying scientific formulas (such as the Kouri et al. 1.80m normalization equation and US Navy equations) reside in the scientific domain and are used for public educational benefit with full bibliographic citation.
However, the website layout, proprietary UI codebase, custom responsive styling, interactive components, text content, and graphics are the intellectual property of ffmicalculatorreal.com. You agree not to:
- Replicate or mirror this website's exact UI design without express written consent.
- Execute automated denial-of-service or scraping attacks that disrupt site availability for other users.
- Misrepresent ffmicalculatorreal as an official regulatory body or sports doping control agency.
4. External Links & Citations
Our pages may contain links or citations to external academic publications (such as PubMed, clinical journals, or academic institutions). We have no control over the content, availability, or policies of third-party platforms and do not assume responsibility for external materials.
5. Limitation of Liability
In no event shall ffmicalculatorreal, its authors, contributors, or affiliates be liable for any direct, indirect, incidental, special, or consequential damages resulting from your use of or inability to use the website, or any physical injury, fitness outcome, or health decision made based on calculations produced by the site.
6. Modifications to Terms
