Medical & Fitness Disclaimer

Important limitations regarding our algorithmic tools.

Human Health & Medical Clause

All calculators provided on Calories.run—including but not limited to the TDEE Calculator, BMI Calculator, Calorie Deficit Planner, and Macro Calculators—provide mathematical estimates based on clinical formulas (such as Mifflin-St Jeor and Katch-McArdle). These calculations do NOT constitute professional medical advice, diagnosis, or treatment.

The human body is highly complex, and mathematical formulas cannot account for individual metabolic damage, thyroid issues, genetic variances, or pre-existing medical conditions. You should always consult a physician, registered dietitian, or qualified healthcare provider before starting any severe calorie deficit, extreme diet, or new exercise regimen.

Relying on any information provided by Calories.run is solely at your own risk.

Veterinary & Pet Health Clause

The Dog and Cat Calorie Calculators use standard resting energy requirement (RER) formulas provided by the World Small Animal Veterinary Association (WSAVA). However, these are strictly baseline estimates. They do not replace professional veterinary advice.

You must not rely on these calculators for pregnant, lactating, growing, or metabolically impaired pets. Always consult a licensed veterinarian to determine the exact nutritional requirements for your pet’s specific breed, age, and medical history.

Algorithmic Accuracy Clause

While every effort is made to ensure the algorithmic accuracy and clinical validity of our formulas, Calories.run assumes no liability for errors, omissions, or health outcomes resulting from the use of our calculators. The mathematical models are designed for the general population and may not be accurate for clinical outliers.
