because you consume your own raw fat and raw meat when fasting.

that might cause you overall feel good or better short-term but worse long-term, your body ate yourself (your own fat and muscle), this is called autophagy.

You get a temporary "high" from the clean internal raw nutrients being mobilized – similar to eating raw meat or raw fat in large amounts.

Long-term it's destructive. Your body is literally eating itself to survive. You deplete irreplaceable stores of raw fat, enzymes, vitamins, and structural proteins faster than you can rebuild them. Once the easy reserves are gone, you start breaking down vital organs, glands, and brain tissue.

For sustained healing and rebuilding, you must constantly supply external raw fat and raw meat from animals.
