A 36-hour fast prompts the body to begin utilizing stored fat for energy. However, this period of food deprivation also carries potential health risks. Individuals undertaking such a fast may experience a drop in blood sugar levels, leading to weakness or dizziness. Dehydration is another concern, as the body doesn’t receive fluid intake from food during this time. While fat metabolism increases, maintaining adequate hydration and monitoring for symptoms of hypoglycemia are crucial. Experts recommend careful consideration and potentially medical consultation before attempting extended fasts. The body’s response can vary based on individual health and activity levels.
