What prolonged fasting can do to the human body | Explained
The article examines the physiological effects of prolonged fasting, triggered by activist Sonam Wangchuk's 19-day hunger strike in New Delhi. It explains that during extended fasting, the body shifts from using consumed calories to burning fat stores, leading to weight loss (2-10%), increased ketones, and decreased blood pressure and blood sugar. Studies cited include a Nature Metabolism trial showing increased coagulation factor XI (raising thrombosis risk) and a Chinese Nature study documenting reduced blood glucose, increased uric acid, and a shift toward fat metabolism. Adverse effects include muscle protein breakdown, headaches, insomnia, and metabolic acidosis. The article notes that risks are higher for individuals with diabetes, low blood pressure, or other medical conditions.
