Terms of Use

By accessing and using peakcalcs.com ("the Site"), you agree to the following terms and conditions. If you do not agree with these terms, please do not use the Site.

Nature of the Service

PeakCalcs provides free online estimation tools for health and fitness metrics, including but not limited to basal metabolic rate, total daily energy expenditure, body fat percentage, one-rep max, macronutrient targets, and related calculations. These tools produce estimates based on published peer-reviewed formulas applied to the inputs you provide.

Not Medical or Nutritional Advice

The information and results provided by PeakCalcs calculators are for general informational and educational purposes only. They do not constitute medical advice, nutritional advice, exercise prescriptions, or professional health guidance of any kind.

Calculator results are estimates derived from population-level formulas. Your actual metabolic rate, body composition, strength capacity, and nutritional needs may differ significantly from any formula's prediction due to individual factors including genetics, medical conditions, medications, measurement technique, hydration, and training history.

Always consult a qualified healthcare professional, registered dietitian, or certified fitness professional before making decisions about your health, diet, or exercise programme based on information from this Site. Never disregard professional medical advice or delay seeking it because of something you read or calculated on PeakCalcs.

Accuracy and Limitations

We make reasonable efforts to ensure the accuracy of formulas and calculations by referencing peer-reviewed scientific publications and running verification tests. However, we do not warrant that all information on the Site is accurate, complete, or current. Formulas may be updated as new research is published, and we may not immediately reflect the latest findings.

PeakCalcs is not responsible for errors in user-provided inputs, browser compatibility issues, or any discrepancies between calculated estimates and actual values.

Calorie and Health Guardrails

Our calculators enforce minimum calorie floors of 1,200 kcal/day for women and 1,500 kcal/day for men. Results below these thresholds include warnings that such intake levels require medical supervision. Pregnancy-related calculators include enhanced disclaimers and do not support deficit calculations. These guardrails exist for user safety and do not constitute medical advice.

To the fullest extent permitted by applicable law, PeakCalcs and its creator shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages arising from your use of or inability to use the Site, including but not limited to damages arising from reliance on calculator results.
