Estimate the daily calorie intake that may help you maintain your current body weight at your selected activity level.
Maintenance calories are an estimate. Day-to-day expenditure changes with movement, training, sleep, body composition and other factors, so use the result as a starting point rather than an exact requirement.

Maintenance calories are the approximate daily energy intake that would match your energy expenditure closely enough to keep body weight relatively stable over time.
Energy expenditure varies from day to day, so a small range better reflects real life than treating one calculated number as perfectly exact.
Use it as a starting point, then compare your intake with your weight trend over several weeks and make gradual adjustments if needed.
