Fasted Training Risk API

Assess muscle loss risk and performance impact for fasted sessions, with strategy recommendations and fueling timing protocol.

Endpoint

  • GET /api/v1/fitness/fasted-training-risk
  • POST /api/v1/fitness/fasted-training-risk/post

Parameters

Name Type Required In Description
fasting_hours number (8-24) Yes Query/Body Current fasting window length.
training_intensity string Yes Query/Body low,moderate,high,very_high.
goal string Yes Query/Body fat_loss,muscle_gain,recomposition,maintenance,performance.
cortisol_stress_score number (1-10) Yes Query/Body Stress score input for risk pressure.
lang string No Query Response language (en,es,de,fr,pt,ja,hi,ar).

Why Use This Endpoint

  • Prevent muscle-loss outcomes in aggressive fasting workflows.
  • Decide when to modify or fuel pre-session.
  • Build safer fasted-training automation in coaching products.
