Jason Fung - Intermittent Fasting for Type 2 Diabetes Reversal | The Diabetes Code Clinic (Part 4)
Dr. Jason Fung explains that type 2 diabetes is essentially the body's inability to manage excess sugar, primarily from diet. He suggests that intermittent fasting can help reverse this condition by giving the body time to burn off excess sugar stored as energy. Fasting is defined as any period when you're not eating, allowing the body to use stored calories. He emphasizes that during fasting, the body uses stored sugar and fat, which can lead to a reduction in blood glucose levels and potentially reverse diabetes. Practical steps include eliminating snacks, especially after dinner, and gradually extending fasting periods. He provides examples of individuals who have successfully reversed their diabetes through these methods, highlighting the importance of reducing meal frequency and avoiding processed snacks. Dr. Fung also addresses common concerns about fasting, such as nutrient intake and managing hunger, suggesting solutions like drinking hot beverages and taking magnesium supplements.
Key Points:
- Intermittent fasting helps reverse type 2 diabetes by allowing the body to burn excess sugar.
- Fasting periods should be extended by eliminating snacks and avoiding eating after dinner.
- Reducing meal frequency to two or three meals a day can help manage blood sugar levels.
- Processed snacks should be avoided as they contribute to higher blood sugar levels.
- Monitoring blood sugar and adjusting medications as needed is crucial during fasting.

2.2. 🔄 Role of Intermittent Fasting in Diabetes Management
3. ⏳ The Role of Fasting in Diabetes Management
- Fasting allows the body to tap into stored sugar and fat reserves, which is crucial for maintaining energy balance.
- During fasting, the body initiates gluconeogenesis and ketogenesis, processes that convert stored glycogen and fat into energy, thus preventing hypoglycemia.
- This metabolic switch is essential to burn excess stored sugar and fat, contributing to weight management and improved insulin sensitivity.
- Conversely, continuous eating without fasting leads to disrupted metabolic processes, resulting in excess sugar and fat retention, which can exacerbate insulin resistance.
4. 🍽️ Nutritional Needs and Fasting
- Body fat serves as a reserve of stored calories, enabling individuals to fast without immediate food intake, particularly when blood glucose is high, which indicates excess energy availability.
- During fasting, it is crucial to supplement nutritional needs with multivitamins to ensure adequate intake of essential vitamins and minerals.
- Lowering blood glucose levels during fasting can allow for medication reduction, which may lead to the remission of type 2 diabetes.
5. ⏰ Timing and Eating Habits
- A standard fasting period typically lasts 12 to 14 hours, spanning from dinner to breakfast the next day, which supports metabolic health by allowing the body to enter a state of repair and energy utilization.
- Eating after dinner disrupts the fasting period, preventing the body from utilizing stored energy and instead promoting the storage of excess calories, which can lead to weight gain.
- Late-night eating results in stored calories rather than burned calories, as the body doesn't have an opportunity to use them before sleep, which negatively impacts weight management and overall health.

7. 🥦 Processed Foods and Their Consequences
- Highly processed foods, often wrapped in cellophane, contribute to poor nutrition compared to whole foods like vegetables.
- To mitigate the negative impact of processed foods, consider adopting intermittent fasting by eliminating snacks, especially processed ones.
- Begin intermittent fasting by stopping eating after dinner and not consuming bedtime snacks.
- Manage hunger and cravings during fasting periods with hot drinks such as tea or water.
- Take magnesium supplements to address cramps that can occur during fasting.
- Monitor blood sugar levels to avoid symptoms of hypoglycemia and adjust salt intake to counteract dizziness.
- Initial headaches from fasting are common but typically decrease over time.
- Processed foods can lead to various health issues, including obesity and chronic diseases, emphasizing the importance of dietary changes.
8. 📝 Implementing Intermittent Fasting
- A patient successfully reversed diabetes and stopped multiple medications by changing his eating habits from six meals a day to a structured intermittent fasting schedule.
- Key steps include reducing carbohydrate intake, maintaining a detailed food journal, eliminating snacks between meals, and avoiding food after dinner.
- Start by adjusting the eating window gradually, either by delaying breakfast or having an earlier dinner, aiming for an 8-hour eating window and a 16-hour fasting period.
- Consistent monitoring of the fasting practice is crucial to ensure effectiveness and sustainability.
- Be prepared for potential challenges such as hunger or energy dips, and adjust the approach as needed to maintain long-term adherence.
