I sure in the heck don't know.
Ketosis is basically a state wherein your body has low supplies of glycogen due to a high fat/protein and low carb food intake. For most people, this is achieved by keeping net carb intake around 30-50g per day maximum. Ketosis will usually begin after a few days of this eating pattern.
When you're in ketosis, your liver starts to produce glycogen as your muscles cease storing it. Your body utilizes the fat in its system, along with your dietary fat, to produce ketones in the body - reservoirs of fat energy - to draw on for fuel in place of glycogen.
It's technically a much more efficient energy source, and your body is better at metabolizing it. You also end up shedding water weight/fat in short order while still maintaining muscle mass/strength.
