How Your Body Burns Fat During a 3-Day Water Fast #ketosis #metabolism

What really happens to your body when you drink only water for 3 days? In this science-based human anatomy documentary, we break down the hour-by-hour effects of a 72-hour water fast on your organs, hormones, metabolism, and brain.

Discover how your body transitions from using glucose to burning fat, how ketosis begins, what happens to your liver and muscles, and how electrolyte balance changes over time. We also explain the potential benefits like increased fat metabolism and short-term insulin sensitivity, along with the risks such as muscle loss, dehydration, low blood pressure, and electrolyte imbalance.

This video explores the science behind fasting, autophagy, ketosis, glycogen depletion, and survival adaptation mode — all explained through clear anatomical visualization.

If you're researching water fasting, intermittent fasting, fat burning, or metabolic health, this documentary gives you medically accurate insights into what happens inside your body after 24, 48, and 72 hours without food.
