The liver plays a crucial role in maintaining blood sugar stability by storing glucose as glycogen and releasing it when needed. In a healthy body, insulin signals the liver to stop releasing glucose when blood sugar is high. However, in diabetes, the liver becomes insulin-resistant and continues to produce glucose, even when blood sugar is already elevated.
Why the Liver Overproduces Glucose in Diabetes
Several factors contribute to the liver’s excessive glucose production in diabetic individuals:
1️⃣ Insulin Resistance in the Liver – Normally, insulin instructs the liver to halt glucose production. In diabetes, the liver ignores this signal, leading to excessive glucose release (Harvard Health).
2️⃣ Glucagon Overactivity – The hormone glucagon stimulates glucose production. In diabetes, glucagon levels remain elevated, further driving the liver to overproduce glucose (American Diabetes Association).
3️⃣ Fatty Liver Disease – Excess fat accumulation in the liver disrupts insulin signaling, making it harder to regulate glucose production effectively (National Institutes of Health).
The Hepatic vs. Underutilization Theory
There are two primary theories explaining diabetes:
- The Hepatic Theory: Diabetes results from excess glucose production by the liver (Gary Taubes).
- The Underutilization Theory: Muscles fail to absorb glucose properly due to insulin resistance.
Renowned researcher Gary Taubes supports the hepatic theory, emphasizing that improving liver function is essential for controlling diabetes.
How to Improve Liver Function and Reduce Excess Glucose Production
Optimizing liver function is crucial in preventing and managing diabetes. Here are effective strategies:
- Lower carbohydrate intake – Reducing carbs helps lower insulin and glucagon demand, improving liver function (Mayo Clinic).
- Increase healthy fats – Consuming foods like avocados, olive oil, and fatty fish supports liver health and reduces insulin resistance (Cleveland Clinic).
- Practice intermittent fasting – Fasting allows the liver to reset its glucose regulation, improving overall metabolic function (Johns Hopkins Medicine).
- Avoid fructose and processed foods – These contribute to fatty liver disease and worsen glucose regulation (National Institute of Diabetes and Digestive and Kidney Diseases).
Final Takeaway
The liver plays a dominant role in blood sugar regulation, and its dysfunction is a key contributor to diabetes. Addressing liver health through dietary interventions, fasting, and improved nutrition is critical for reversing metabolic disorders and achieving better long-term health outcomes.

This is a fascinating insight into the liver’s role in diabetes and blood sugar regulation. I had no idea the liver was so central to this process, especially in the context of insulin resistance. Gary Taubes’ hepatic theory makes a lot of sense—focusing on liver health seems like a practical approach to managing diabetes. The idea of using dietary interventions and fasting to improve liver function is intriguing, but I wonder how accessible these strategies are for everyone. Do you think these methods could work for all types of diabetes, or are they more effective for specific cases? I’d love to hear more about how these strategies have worked in real-life scenarios. What’s your take on the balance between medical treatments and lifestyle changes in managing diabetes?
Thank you for your insightful comment!
You’re absolutely right—many people don’t realize how central the liver is to blood sugar regulation. While these lifestyle strategies may not replace medical treatment, they can complement it effectively, especially in type 2 diabetes. For type 1 diabetes, insulin therapy is essential, but improving liver function can still help with overall metabolic balance and reducing insulin resistance.
