Advanced Recovery Tool

Recovery-Driven Calorie Engine

Set a smarter daily calorie + macro target using sleep, HRV/RHR changes, stress, soreness, activity load, and training type.

What this tool does

This calculator adjusts your calorie and macro target for today based on recovery signals (sleep, HRV/RHR trend, soreness, stress) plus expected activity load.

Who and when to use it

Use if your wearable and recovery metrics swing day to day.
Use on training days to avoid under-fueling hard sessions.
Use on poor-recovery days to avoid forcing aggressive deficits.
Best for intermediate/advanced users running weekly training blocks.

How to use this tool (step by step)

Start with realistic maintenance calories and body weight.
Enter recovery markers from your last 24h (sleep, HRV/RHR delta, soreness, stress).
Select today’s planned session type and expected steps.
Run the engine and apply the output for one day only.
Re-check after 7-14 days of trend data before changing weekly baseline calories.

Example interpretation

If readiness drops (poor sleep + HRV down + RHR up), this tool may keep protein high and shift energy toward recovery-supportive carbs instead of forcing a deep cut. If readiness is strong, it supports normal training fueling and execution.

FAQ

Should I use this instead of a weekly plan?

No. Use it as a day-level adjustment layer on top of your weekly macro structure.

Can I use this without a wearable?

Yes, but estimate HRV/RHR deltas conservatively and rely more on sleep + soreness + stress signals.

How often should calories change?

Daily output can vary, but weekly baseline changes should usually wait for 1-2 weeks of trend data.

What if output feels too high or too low?

Adjust maintenance input first. Most unstable outputs come from unrealistic baseline calories.

Is this for medical recovery?

No. This is nutrition planning guidance, not medical advice.
