FAQs

What’s the difference between BMR and TDEE?

BMR is the calories your body burns at rest. TDEE (maintenance calories) adjusts BMR for your activity level to estimate daily energy needs.

How do I choose the right activity level?

Pick the level that reflects your typical week, not your best week. If you’re unsure, start with moderate and adjust based on real-world weight changes over a few weeks.

What calorie deficit or surplus should I use?

A moderate change (often around 250–500 kcal/day) is a common starting point, but individual needs vary. Consider health conditions and consult a qualified professional for personalized guidance.
