What Happens If You Fast for 7 Days Straight? (Science Explained)

Описание: Have you ever wondered what really happens inside your body when you stop eating for 7 straight days?
In this video, we break down the science-backed truth behind a full 7-day water fast — from the moment your last meal is digested to the deep cellular changes that occur by day seven. Using modern research and evolutionary biology, we explain exactly how your body adapts, survives, and transforms during prolonged fasting.
You’ll discover how your body switches from burning glucose to fat, why ketones fuel sharper brain function, and how autophagy activates your body’s internal repair system to clean out damaged cells. We also explore how fasting can reduce inflammation, improve metabolic health, and trigger immune system renewal.
But fasting isn’t just about benefits. This video also covers the real risks — including dehydration, electrolyte imbalance, muscle loss, and the dangerous mistake many people make when breaking a long fast. We explain why hydration and electrolytes are critical, and how to end a fast safely to avoid refeeding syndrome.
Whether you’re curious, researching, or considering fasting yourself, this video gives you a complete, honest, science-based breakdown of what happens during a 7-day fast.
