Your food diary, translated into hormones
Ration estimates your cortisol and glycogen response from what you eat and when you train.
You log meals and workouts, but nothing tells you what they did to your energy, stress, and recovery.
A forecast, not a lecture
Ration runs your logged foods and exercise through a mechanistic model and draws the estimated response curve for your day.
- Cortisol impact from meal timing and training
- Glycogen status through the day
- See how moving one meal changes the curve
Grounded in research
The model is built from published human data. Every article that explains it cites the studies.
Common questions
Is this a medical device?
No. It is an educational estimate built from published research, not a diagnosis or a lab result.
What does it need from me?
Just your food and exercise log. No wearable required.
