Who should speak to a clinician first
Anyone pregnant or breastfeeding; with diabetes or blood-sugar medication; with a history of eating disorders; with cardiac, kidney, or liver conditions; on medications that may be affected by fasting; underweight; under 18.
When to stop fasting
Persistent dizziness, fainting, chest pain, severe headache, confusion, irregular heartbeat, vomiting, or anything that feels wrong. Break the fast and seek medical attention.
Longer fasts and medical clearance
Fasts beyond 48 hours warrant prior clinician review, especially with any pre-existing condition or medication.
Refeeding caution
Long fasts require careful re-introduction of food. Refeeding syndrome is rare but serious. Follow structured guidance.

Eating disorder caution
Fasting frameworks can be harmful for individuals with disordered eating. If this applies to you, please prioritize professional support over our platform.
Medication caution
Many medications interact with fasting (insulin, blood pressure, blood thinners, more). Do not adjust medication without your prescriber.
