📚 Understanding Your Results

🔥 BMR (Basal Metabolic Rate)

Your BMR is the calories your body burns at complete rest — just to keep your heart beating, lungs breathing, and organs functioning. This calculator uses the Mifflin-St Jeor equation (2002 study, most accurate for most adults).

⚡ TDEE (Total Daily Energy Expenditure)

TDEE = your BMR × an activity multiplier. It represents the total calories you burn in a day. This is your maintenance number — eat less to lose weight, more to gain.

⚠️ Accuracy Disclaimer

Equations have ±10% variance. Athletes, older adults, and those with hormonal conditions may see different results. Use as a starting point and adjust based on real-world results over 2–3 weeks.
