These are estimates based on Mifflin-St Jeor, one of the best-evidenced calorie formulas available. Other formulas exist and give slightly different numbers — all are estimates. Use this as a starting point: track your weight trend over 2–3 weeks and adjust by 100–200 kcal if needed.
Your numbers are just the start.
Calculators give you a starting point. The real work happens with a coach who knows your schedule, your habits, and what's actually getting in the way.
If that sounds useful, we offer a free initial consultation — no commitment, no hard sell. Just a conversation to see if we're the right fit, or if we can point you in the right direction.
