Compare two established maintenance-calorie estimates instead of relying on a single formula.

Moderately active male
30 years old, 180 lb, 70 in, moderate activity
A common maintenance-calorie estimate where method comparison is more useful than hyper-precise calorie targets.
Result: Mifflin and revised Harris-Benedict usually land in the same general maintenance zone, but the difference is still worth seeing.
Active female cut baseline
35 years old, 145 lb, 66 in, active
Useful when someone wants a maintenance anchor before deciding how aggressive a cut or surplus should be.
Result: The TDEE estimate gives a maintenance reference point before any goal-specific adjustment is layered on.
Very active athlete
26 years old, 205 lb, 74 in, very active
Higher activity multipliers amplify even small BMR differences between methods, which is why method spread deserves attention.
Result: At high activity levels, the method gap can become large enough to matter for planning and weight-trend interpretation.
