Fat Burning Power of Fasting: 12 Hours, 24 Hours and 48 Hours Explained

In this episode, Dr. Jockers breaks down exactly what happens inside your body during a 12, 24, and 48-hour fast. You’ll discover how these fasting windows affect fat burning, metabolism, and even your brain’s performance. The science behind it will show you why fasting is far more powerful than just skipping meals.   You’ll also learn how fasting lowers insulin, boosts growth hormone, and increases ketones—helping your body preserve muscle while burning fat. These shifts not only fuel your energy but also enhance mental clarity, creativity, and focus. The longer the fast, the deeper the benefits for your body and brain.   Beyond fat burning, fasting activates cellular repair processes like autophagy and stem cell production. These changes promote gut health, reduce inflammation, and support anti-aging at a deep level. By understanding these stages, you’ll be able to create a fasting routine that works best for your unique health goals.     In This Episode:  00:00 Introduction to Intermittent Fasting 03:20 The Science of Fasting: 12 to 14 Hours 08:40 The Science of Fasting: 16 Hours 14:03 The Science of Fasting: 20 to 24 Hours 17:43 The Science of Fasting: 3 to 5 Days 18:43 Fasting Strategies and Recommendations 20:39 Conclusion and Final Thoughts   If you want to burn belly fat…boost your energy levels…balance blood sugar…or relieve swelling in your legs or feet… Then you need to check out PureHealth Research immediately.
