Unlocking the Link: How Insulin Resistance Drives Metabolic Syndrome

Type 2 diabetes was long considered an irreversible and progressive disease due to the belief that it involved “pancreatic burnout.” However, newer research shows that type 2 diabetes is actually reversible in many cases. This is because the underlying cause is not permanent damage to the pancreas, but rather a reversible dysfunction caused by ectopic fat deposition.

According to the “twin cycles” hypothesis proposed by Dr. Roy Taylor, type 2 diabetes involves two cycles – a liver cycle and a pancreatic cycle:

The Liver Cycle

• A diet high in refined carbs and constant eating leads to chronically high insulin levels
• The excess insulin promotes fat storage in the liver, leading to fatty liver disease (hepatic steatosis)
• Fatty liver causes hepatic insulin resistance, which is an overflow phenomenon rather than true starvation of cells
• With fatty liver, cells are already overloaded with glucose and fat. Additional insulin cannot force more glucose into overloaded cells.
• The post-prandial hyperinsulinemia leads to backup of glucose inside liver cells due to lack of capacity to store more energy
• This intracellular glucose backup causes reduced insulin signaling and glucose uptake – perceived as insulin resistance
• The liver insulin resistance and hyperinsulinemia form a vicious cycle promoting further dysfunction

The Pancreatic Cycle

• The excess fat made in the liver gets exported and deposited in the pancreas as well over years
• Pancreatic fat accumulation impairs insulin secretion by beta cells
• This leads to reversible dysfunction of the pancreatic beta cells rather than permanent damage
• The beta cell dysfunction reduces insulin production, leading to hyperglycemia
• Thus high blood sugars emerge as beta cells fail to compensate for insulin resistance

Implications of diabetes

• Both phases involve ectopic fat deposition – not permanent “burnout” of cells
• Type 2 diabetes is reversible in many cases by addressing root causes of hyperinsulinemia and excess body fat
• Losing even 10-15% of weight can improve fatty liver and pancreas, restoring normal glucose metabolism
• Lifestyle interventions like diet, exercise, fasting can all help reverse type 2 diabetes by reducing insulin levels and body fat
• A disease model focused on reversibility opens up new pathways to treating type 2 diabetes for clinicians

In summary, seeing type 2 diabetes as a reversible metabolic disorder enables a more empowering approach focused on lowering insulin and body fat rather than just managing blood sugars. Lifestyle measures like diet, activity and fasting should be the foundation of treatment even before medications are considered.
