How to use this calculator

  • Enter actual sleep duration.
  • Rate sleep quality from 1 to 10.
  • Add night wake-ups and your target sleep duration.
  • Calculate diet recovery and hunger-risk signals.

What the result means

Short or poor sleep can increase perceived hunger, reduce training recovery, and make dieting harder to sustain. The score estimates recovery support for fat loss.

Diet recovery score = duration score + quality score − wake-up penalty − sleep debt penalty.

This calculator estimates behavioral risk, not hormones or clinical sleep disorders.

Example calculation

Seven hours of sleep with quality 8/10 and one wake-up gives a good recovery score but still leaves one hour of sleep debt against an 8-hour target.

Tips for better results

  • Keep bedtime and wake time consistent.
  • Avoid late caffeine if cravings rise.
  • Treat sleep as part of the diet plan, not a separate issue.
