Daily calorie estimates typically combine a resting-energy equation using age, height, weight and sex with an activity multiplier. The result is a starting estimate, not a measurement of your metabolism; real needs vary with body composition, health, medications and activity.
Track your average intake and body-weight trend over several weeks rather than treating one number as exact. Activity categories are approximate, and exercise trackers can overestimate calories burned. Avoid extreme calorie restriction.
