Most cases aren’t caused by “insulin resistance.” They are caused by diet—and that means they can be prevented or reversed.
For decades, type 2 diabetes has been explained as insulin resistance, but this theory fails to answer key biological questions. In this video, Dr. John on Health breaks down a clearer, science-backed explanation for high blood sugar: fuel overflow caused by excess fatty acids. When high-carb diets overload the body with glucose, the liver converts the excess into fatty acids. Once fat cells reach capacity, these fatty acids spill into the bloodstream—forcing muscle cells to burn fat instead of glucose. As a result, glucose remains trapped in the blood, causing rising blood sugar levels even when insulin is present.
This process is called the Fatty Acid Burn Switch, and it provides a more accurate explanation of type 2 diabetes than insulin resistance alone.
What You’ll Learn
- Why insulin resistance theory doesn’t explain key diabetes behaviors
- How fuel overflow forces cells to burn fatty acids, not glucose
- Why high blood sugar continue even with insulin
- The real metabolic driver of type 2 diabetes
- Why remission is possible with targeted diet strategies
A Path Toward Remission
If type 2 diabetes is caused by fuel imbalance, not defective insulin response, then the right dietary strategies can help restore normal metabolism. Remission is possible. Learn more at DrJohnOnHealth.com.
