Results are population-based estimates and can differ from measured values by 10–20% for individuals with atypical body composition. See our Methodology page for full formula sources and references. Consult a qualified healthcare professional before making medical or dietary decisions.

The 卡路里计算器 uses an established, peer-reviewed formula endorsed by leading health organisations such as the WHO, CDC, or NIH where applicable. The specific formula is chosen for its validated accuracy across diverse adult populations under normal conditions.
