Is water fasting really so effective and useful?

The practice of complete abstinence from food while maintaining a drinking regime triggers autophagy, the process of recycling damaged cellular organelles. When glycogen reserves are depleted, the liver switches to ketogenesis, breaking down fat stores to nourish the brain.
Physiological changes during water starvation carry both therapeutic potential for metabolism and serious risks for the electrolyte balance of the blood.
Biochemical changes in the rejection of nutrients
After three days without carbohydrates, the body exhausts the reserves of the liver and rebuilds the enzymatic systems. Lowering insulin levels to basal levels removes the blockage from lipase, the enzyme responsible for adipocyte lipolysis.
- slows down the rate of basal metabolism to conserve energy;
- increases the sensitivity of cellular receptors to glucose;
- the marker of systemic inflammation, C-reactive protein, decreases.
During this period, the kidneys begin to actively remove sodium and potassium, which requires strict control of the mineralization of consumed water to prevent arrhythmia.
Risks of prolonged nutritional deprivation
Fasting for more than seven days provokes catabolism of muscle tissue, as the brain requires amino acids for gluconeogenesis. Loss of muscle mass leads to sarcopenia and decreased strength endurance.
- bile thickens, increasing the likelihood of concretions;
- blood pressure drops due to hypovolemia;
- the load on the kidneys increases due to the excretion of ketone bodies.
Medical monitoring is required to prevent ketoacidosis, in which blood acidity shifts to critical levels, threatening the functions of the central nervous system.
Withdrawal from starvation and refeeding syndrome
The abrupt introduction of carbohydrates after prolonged abstinence causes the release of insulin and the rapid movement of phosphates inside the cells. The syndrome of renewed nutrition leads to acute heart failure and muscle spasms due to a lack of electrolytes in the plasma.
The first meals should consist of light vegetable broths with the gradual addition of heat-treated fiber and easily digestible protein. The safe adaptation of the gastrointestinal tract takes the same amount of time as the period of abstinence itself. Gioca su Casino Midas e metti alla prova la tua fortuna.
