What should you know about water fasting — and is it medically safe?

Water fasting involves consuming only water for a defined period. In this episode, we explain the metabolic effects, potential risks, and when medical supervision is essential, particularly within European clinical guidelines.

You’ll learn:

• What water fasting is and how it differs from intermittent fasting

• How the body shifts from glucose to ketone metabolism during prolonged fasting

• Potential short-term effects: dehydration, electrolyte imbalance, dizziness, low blood pressure

• Risks for people with diabetes, cardiovascular disease, eating disorders, or on prescription medication

• Warning signs that require medical assessment, including fainting, confusion, or palpitations

• Why rapid weight loss during fasting may reflect fluid loss rather than sustained fat reduction

• Situations where medical support or prescription requests related to fasting may be declined for safety reasons

We also discuss safer, evidence-based approaches to weight management and metabolic health.
