The information provided by Trendy String — including all calculators, trackers, and Journal articles — is for general educational and informational purposes only.
Nothing on this site constitutes medical advice, diagnosis, or treatment. Our calculators use established formulas (such as the Mifflin-St Jeor equation, WHO BMI categories, or the U.S. Navy body fat method) to give you an estimate — not a clinical assessment. Always seek the advice of a physician or other qualified health provider with any questions you may have regarding a medical condition, medication, or before making changes to your diet, exercise, or lifestyle.
Using this website, its calculators, or reading its articles does not create a doctor-patient relationship between you and Trendy String or any of its contributors.
Formulas used across our calculators are based on population averages and standard clinical references. Your individual body composition, health history, medications, and other factors can affect how well a formula's estimate matches your actual physiology. Treat every result as a starting point for a conversation with your healthcare provider, not a final answer.
If you are experiencing a medical emergency, call your local emergency number immediately. Do not rely on this website for urgent or emergency medical guidance.
Our articles link to external, authoritative sources (such as the CDC, WHO, and NIH) for further reading. We are not responsible for the content of external websites, and linking to them does not imply an endorsement of their entire content.
Some articles on this site may include affiliate links to products (for example, on Amazon). If you make a purchase through one of these links, we may earn a small commission at no extra cost to you. We only link to products relevant to the topic being discussed.
