Self check-ins are completed independently within the app. No direct messaging or ongoing feedback between consultations.
Designed for those who want structure, guidance, and accountability without needing high-touch daily support.
Designed for those who want the highest level of support and a fully guided approach.
This calculator estimates your daily energy needs using Mifflin–St Jeor (BMR). If you enter a reliable body fat %, it can optionally estimate BMR using lean mass instead.
Your estimated maintenance calories are calculated by multiplying BMR by your selected activity level (PAL).
Instead of giving one “perfect” number, it provides a calorie range to reflect real-world variation, then recommends a starting point inside that range based on your current context (e.g., stress/sleep/dieting history).

WHY ACCURACY MATTERS
Most calculators can be meaningfully off for individuals due to differences in daily movement (NEAT), dieting history, sleep/stress, cycle status, medications, and training load. That’s why this tool uses a range + calibration approach, not a single rigid number.
DISCLAIMER:
This calculator provides estimates only and is not medical nutrition therapy. It is not suitable as a standalone tool for people who are pregnant/postpartum/breastfeeding, under 18, or with a history of disordered eating/amenorrhoea; in these cases, aggressive deficits are restricted and professional support is recommended. If you have a medical condition requiring therapeutic nutrition (e.g., kidney disease, type 1 diabetes, complex pregnancy issues), please seek individualised guidance from a qualified health professional before making significant dietary changes.
