Fasting for 36 hours is a popular online trend touted as a bodily “reset.” While advocates promote benefits for metabolism and mental clarity, the reality is more complex than social media often portrays.
The process involves the body initially burning available glucose for energy. Once that is depleted, it turns to stored glycogen before increasingly utilizing fat reserves.
In extended fasts, this can lead to ketosis, where fat becomes the primary fuel. Some also cite increased autophagy, a cellular recycling process that may be enhanced when nutrients are scarce.
Individual experiences differ significantly. Some people feel more focused and less bloated, while others struggle with fatigue, irritability, and poor concentration.
Risks do exist, including dizziness, headaches, dehydration, and electrolyte imbalances, particularly if hydration and nutrients are neglected.
Such fasting is not advisable for everyone. It can be dangerous for those who are pregnant, have diabetes or low blood pressure, a history of eating disorders, or take certain medications.
Experts suggest starting cautiously, staying hydrated, and consulting a doctor before longer fasts. Ultimately, sustainable health is built on consistent nutrition, exercise, and sleep, not extreme short-term measures.
