Disclaimer & Notice

1. Educational use only

Every calculator and tool, table and article on dmbio is published for general educational, informational and self-reflection purposes only. Nothing on this site is professional medical, mental health, nutritional, fitness, legal or financial advice, and nothing here creates a doctor-patient, therapist-client or advisor-client relationship.

2. Health, fitness and nutrition tools

Health, fitness and nutrition calculators and tools return population-level estimates based on published formulas. They cannot account for your full medical history, medications, body composition, ethnicity, pregnancy, lactation, growth, recovery from illness or any individual factor.

Speak to a qualified healthcare professional before changing your diet, hydration, training or sleep based on these numbers, especially if you are under 18, over 65, pregnant or breastfeeding, an athlete, or living with diabetes, heart, kidney, thyroid or any other chronic condition.

Eating disorders: please do not use a calorie or macro tool without support if you are recovering from disordered eating. In the UK contact Beat. In the US contact the National Eating Disorders Association.
