Therapeutic Fasting

Definition

Prolonged and voluntary abstention from food under medical supervision for therapeutic purposes, distinct from religious fasting or intermittent fasting, aiming for specific medical benefits.

How it works

Therapeutic fasting triggers deep biological processes: after 12-16 hours without food, the body exhausts its glycogen reserves and shifts to lipolysis for energy. This metabolic transformation may promote autophagy (cellular cleaning), reduce inflammation, and improve insulin sensitivity. It can be used to treat certain conditions such as resistant epilepsy, severe obesity, or metabolic disorders. However, prolonged fasting requires strict medical supervision due to risks (nutritional deficiencies, cardiac arrhythmias, electrolyte disturbances). Duration and modalities must be adapted individually according to health status.

Role

Therapeutic intervention mobilizing energy reserves and cellular detoxification mechanisms under medical supervision.

Examples

• Fasting for 24-48 hours to treat certain forms of epilepsy, Therapeutic intermittent fasting protocol (16-20 hours of fasting), Brief supervised fasting to reset metabolic markers

Recommendations

Therapeutic fasting should only be undertaken under strict medical supervision with regular biological monitoring. Ensure adequate hydration and take prescribed vitamin supplements. Gradual transition to refeeding is necessary to avoid refeeding syndrome.

Key takeaway

Therapeutic fasting may offer specific metabolic benefits but requires professional medical guidance.
