Deep dives
The Risks of 72-Hour Water Fasting
Engaging in a 72-hour water fast can lead to detrimental effects, especially for those who are metabolically inflexible. Many people, including those with normal weight, struggle to switch their energy source from glucose to fatty acids when deprived of food. This inability results in the depletion of glucose and glycogen stores within the first day, leaving the brain without sufficient energy, which can cause fatigue and poor performance even in regular activities like exercising. This situation is compounded by high insulin levels, which prevent the release of stored fat from fat cells, thus exacerbating feelings of hunger and weakness, making such fasts impractical and potentially harmful for most individuals.
