Short Summary
Main recommendation: Practice intermittent fasting by stopping all snacking and eating, including bedtime snacks, after dinner, so the body has time to burn off excess blood sugar and reverse type 2 diabetes. Dr. Jason Fung says this can reduce or eliminate diabetes medications, and that it works alongside cutting carbohydrates and keeping a food journal.
Key Points
- Dr. Fung explains type 2 diabetes as the body holding too much sugar (glucose) from the diet, likened to a sugar bowl that spills over into the blood.
- Fasting means any period without eating; the body then draws stored calories and sugar back out of storage and burns them.
- Snacking has risen sharply since the 1970s, and snacks often add total intake and tend to be highly processed carbohydrates.
- A real-life example, Eduardo, went from many medications to none after his eating was reduced from six meals a day.
Details Worth Noting
- Concrete instructions: Keep a normal overnight fast of about 12 to 14 hours, with dinner around 7 p.m. and breakfast between 7 and 8 a.m., and eat nothing after dinner.
- Concrete instructions: Eat three meals a day, or two if preferred, with no snacks in between; drink water, tea, coffee, or herbal tea during fasting periods.
- Concrete instructions: When hungry between meals, drink something hot such as tea or hot water; hunger typically settles if ignored.
- Concrete instructions: Consider a magnesium supplement for cramps, which some people experience while fasting.
- Concrete instructions: Once the no-snack habit is established, gradually shrink the eating window to about 8 hours, for example by eating breakfast later or dinner earlier.
- Concrete instructions: Keep a food journal, check blood sugars, and fast safely. If dizzy or showing low blood sugar symptoms such as shaking or sweating, check sugar levels; dizziness may signal low blood pressure, which may require medication adjustment or a little salt, per Dr. Fung.
- Headaches are common when starting fasting; according to Dr. Fung they usually go away after a while, though the cause is not well understood.
- Dr. Fung states that if blood glucose drops, medications can be reduced, potentially to the point of remission. He also says a multivitamin can cover nutrient needs if concerned.
Bottom Line
Intermittent fasting, centered on eliminating snacks and late-night eating, is presented here as a practical way to lower blood sugar and reduce medication needs, but this is the speaker's account and not professional medical advice; medication changes should be made with a clinician.
