## What BMR means



BMR is an estimate of the calories your body uses at rest. It is not your full daily burn because it does not include walking, workouts, job activity, digestion, or general movement.

TDEE adds an activity multiplier to BMR. That TDEE estimate is usually the better starting point for setting calorie targets.
## Why women should treat calculators as estimates



No calculator knows your exact body composition, cycle-related water shifts, training adaptation, step count, or dieting history. The result is a starting point, not a verdict.

Use the estimate for two to three weeks, track body weight trends and energy, then adjust. Daily scale changes can be noisy, so use averages when possible.
## Macro priorities



Protein supports muscle retention, recovery, and fullness. Fat supports preferences and dietary flexibility. Carbs often support training quality and make many diets easier to sustain.

The best macro plan is one you can repeat. Start simple, then adjust around hunger, training, digestion, and food preferences.
## FAQ

### What BMR formula does this use?

It uses the Mifflin-St Jeor formula, a common estimate for general calorie planning.

### Are 1200 calories enough for women?

Sometimes 1200 appears as a lower bound in calculators, but it is not automatically appropriate. Activity, size, training, hunger, and medical context matter.

### How often should I recalculate macros?

Recalculate after meaningful weight change, activity change, goal change, or several weeks of stalled progress.
