Maintenance calories are commonly estimated from resting metabolic rate plus activity. The estimate is a starting point and should be adjusted based on stable weight trends.
How to interpret the result
If weight is stable over several weeks, your actual maintenance may be close to your average intake. Day-to-day changes are normal.
Safety and limitations
Maintenance estimates are general guidance and should be adapted to individual needs and qualified advice where relevant.
