Frequently asked questions
How are calorie needs calculated?
We estimate your BMR (Mifflin-St Jeor) and multiply by an activity factor to get TDEE — your maintenance calories.
How big a deficit is safe?
Roughly 250–500 kcal/day is a common, sustainable range for steady loss, but individual needs vary — consult a professional.
Is this medical advice?
No — it's an educational estimate. Speak to a healthcare or nutrition professional for personal guidance.
