It estimates resting energy only. Total daily needs are usually higher once movement, exercise and digestion are included.

Test how age or body weight changes would affect estimated resting metabolism.

The primary result uses the Mifflin-St Jeor equation. The comparison panel also shows a revised Harris-Benedict estimate so you can see how equation choice changes the result.
RMR and BMR are both resting-energy estimates, but BMR is typically measured under stricter lab conditions. TDEE is higher because it includes activity, movement and digestion.
Total kcal/day rises with body size, so kcal/kg/day helps interpret the result relative to weight. It is an estimate, not a diagnosis of metabolic health.
Results are estimates generated locally in your browser from standard resting metabolic rate equations. They are for informational purposes only, not medical, nutrition, diagnostic or weight-management advice. RMR can vary with body composition, medications, hormones, illness, pregnancy, recovery status and measurement conditions. For clinical nutrition planning, consult a qualified healthcare professional or registered dietitian.
