Terms & Disclaimer

Last updated: March 29, 2026

By accessing and using NutriMath ("we," "us," or "our") at nutrimath.net, you agree to the following terms. If you do not agree, please do not use the site.

For Educational Purposes Only

NutriMath provides free, browser-based health and fitness calculators for educational and informational purposes only. All results are estimates generated by published scientific formulas based on the inputs you provide. They do not constitute medical diagnoses, treatment recommendations, or guarantees of accuracy for any individual.

Not Medical, Nutritional, or Fitness Advice

Nothing on NutriMath constitutes medical, nutritional, dietary, or fitness advice. We are not doctors, registered dietitians, certified nutritionists, personal trainers, or licensed health professionals. We do not recommend specific diets, supplements, exercise programs, or health interventions. All educational content on this site is general in nature and should not be relied upon as a substitute for professional advice tailored to your individual circumstances.

Before making any changes to your diet, exercise routine, or health regimen — including calorie restriction, macro adjustments, or new training programs — consult with qualified healthcare professionals who can evaluate your medical history, current health status, and individual needs.

Limitations of Calculator Results

Calculator results are approximations based on population-level research. Individual results will vary based on factors our tools cannot account for, including but not limited to:

  • Your genetics, metabolic rate, and hormonal profile
  • Existing medical conditions and medications
  • Your actual body composition vs. estimated values
  • Activity level, which is self-reported and inherently imprecise
  • Thermic effect of food, non-exercise activity thermogenesis (NEAT), and adaptive thermogenesis
  • Age-related metabolic changes not fully captured by formulas
  • Differences between laboratory-measured and estimation-based body fat methods

Formula Accuracy

Our calculators implement published, peer-reviewed formulas (Mifflin-St Jeor, Harris-Benedict, Katch-McArdle, US Navy body fat method, and others). These formulas were developed from specific study populations and have known limitations. We document which formula each calculator uses and explain its accuracy range. No estimation formula is a substitute for clinical measurement.

No Endorsement

NutriMath does not endorse, recommend, or promote any specific supplement, diet plan, fitness product, or health service. References to research studies, formulas, or health organizations are for educational context only.

Privacy

All calculations run entirely in your browser. We do not collect, store, or transmit any health data you enter into our calculators. For full details, see our Privacy Policy.

Intellectual Property

All content on NutriMath — including text, calculators, code, design, and graphics — is owned by NutriMath and protected by applicable copyright and intellectual property laws. You may use our calculators for personal, non-commercial purposes. You may not reproduce, distribute, or create derivative works from our content without written permission.

Third-Party Links

NutriMath may contain links to third-party websites for reference or additional information. We do not control, endorse, or assume responsibility for the content or practices of any third-party sites.

Limitation of Liability

To the fullest extent permitted by law, NutriMath and its owners shall not be liable for any direct, indirect, incidental, consequential, or special damages arising from your use of (or inability to use) our calculators or content. This includes, without limitation, damages from inaccurate calculations, health outcomes, or decisions made in reliance on our tools. You use this site and its tools entirely at your own risk.

We may update these terms from time to time. Changes will be posted on this page with an updated revision date. Your continued use of NutriMath after changes are posted constitutes acceptance of the revised terms.
