Frequently Asked Questions
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the energy your body needs at complete rest. TDEE (Total Daily Energy Expenditure) adds your activity level on top, giving your total estimated daily calorie needs.
How is this calculated?
Using the Mifflin-St Jeor equation, widely regarded as one of the more accurate BMR formulas for the general population, combined with an activity multiplier.
Should I eat exactly this many calories?
TDEE is a starting estimate for maintaining your current weight. To lose or gain weight, you’d typically adjust below or above this number — a registered dietitian can help tailor this to your goals.
Is this accurate for everyone?
The Mifflin-St Jeor equation is well-validated for most adults, but research shows it tends to underestimate needs for athletes and for adults over 65 with obesity. If either applies to you, treat this as a starting point to adjust from rather than a precise target.
