For about a decade, a person can develop fatty liver without any symptoms. This condition impairs insulin function, causing insulin resistance and eventual pancreatic failure, which culminates in a Type 2 diabetes diagnosis. The disease is often established long before it is detected.
Dr. Unwin's clinical data shows a 93% success rate in normalizing blood sugar for pre-diabetics using a low-carb diet. This effectiveness drops to 73% for early-stage Type 2 diabetics and just 50% after five years, underscoring the urgency of early intervention.
