How does fat leave the body during ketosis?

When your carb intake is very low, these glucose stores drain down. Since your body doesn't have enough carbs to burn for energy, it burns fat instead. As your body breaks down fat, it produces a compound called ketones. The ketones, or ketone bodies, become your body and brain's main source of energy.

Yes, a 16-hour fast can start to put you in a state where your body begins burning fat for fuel and producing ketones, especially if you're already eating low-carb, but you might not be in full, deep ketosis until closer to 18-24 hours or longer, depending on your diet and body, as it takes time to deplete glucose stores. Many people enter mild ketosis overnight (12+ hours), but longer fasts (20+ hours) or combining with low-carb eating often ensures deeper fat burning.
