Fatty Liver Expert: Your Liver Is Filling With Fat Right Now - Dr David Unwin

What It Covers

Dr. David Unwin, ranked among the UK's top 10 most influential doctors in 2018, explains how fatty liver disease and insulin resistance silently progress for up to a decade before type 2 diabetes develops. He presents data from 13 years of low-carbohydrate patient trials, his teaspoon-of-sugar food equivalency system, and his wife's GRIN behavior-change framework for sustainable dietary transformation.

Key Questions Answered

• •Hidden Sugar in Staple Foods: Using the glycemic load calculation, 150g of boiled rice contains 10 teaspoons of sugar equivalent, a medium baked potato contains 9, a ripe banana contains 6, and unsweetened cornflakes contain 8 — all exceeding a standard chocolate bar at 7.5. Carbohydrates are structurally glucose molecules bonded together; digestion breaks those bonds, releasing free glucose regardless of whether the food tastes sweet. Checking total carbohydrate content on labels, not just added sugar, is the practical corrective action.
• •The Decade-Long Silent Progression: Fatty liver develops silently for approximately 10 years before type 2 diabetes is diagnosed. Excess dietary glucose is converted to fat stored in the liver by insulin, which then causes insulin resistance, forcing the pancreas to overproduce insulin. Fat simultaneously accumulates in the pancreas, eventually collapsing its insulin-producing capacity. Prediabetes caught early yields a 93% chance of normal blood sugar on low-carb; waiting until full type 2 diabetes drops that to 73%, and waiting five more years drops it to 50%.
• •Waist-to-Height Ratio as a Free Metabolic Screening Tool: Cut a piece of string equal to your height, fold it in half, and wrap it around the widest part of your abdomen. If it does not reach, your waist exceeds half your height, signaling elevated visceral fat and likely insulin resistance. Abdominal fat is metabolically more dangerous than fat stored on limbs because it directly correlates with fatty liver progression. This costs nothing and requires no medical appointment, making it a practical first self-assessment step.
• •Low-Carb Reversal Rates Across 13 Years of Patient Data: Dr. Unwin has documented 157 cases of drug-free type 2 diabetes remission in his North Liverpool practice since 2013. Beyond blood sugar normalization, patients consistently reported liver function improving by 33–50% within weeks, blood pressure normalizing, weight loss, reduced hunger, and improved cognitive clarity. He also personally experienced needing one hour less sleep per day and eliminating a daily lunchtime nap. These outcomes emerged without pharmaceutical intervention, using dietary change as the primary tool.
• •Ultra-Processed Food Addiction as a Clinical Reality: Approximately 14% of the population meets criteria for ultra-processed food addiction, according to research by clinical psychologist Dr. Jen Unwin. Intelligent, high-functioning individuals repeatedly consume foods they know cause harm because the mechanism mirrors drug or alcohol addiction, not simple lack of willpower. The practical protocol for addressing it involves three steps: honest self-identification of the specific trigger foods, committing to abstinence rather than moderation, and securing non-judgmental social support — since policing behavior from loved ones drives concealment and worsens outcomes.
• •The GRIN Behavior-Change Framework: Developed by Dr. Jen Unwin from distilled CBT research, GRIN stands for Goals, Resources, Increments, and Noticing. The process involves specifying a concrete future health goal, identifying past strategies that worked, defining one small realistic step today, and articulating what a good day feels like. The framework deliberately avoids blame and focuses energy forward. Dr. David Unwin applies it in nearly every clinical consultation, finding it more effective than prescriptive advice because it builds intrinsic motivation from the patient's own experience and values.
• •Sugar, Insulin, and Cancer Risk: Eight forms of cancer are strongly associated with type 2 diabetes. Chronically elevated insulin inhibits apoptosis, the process by which damaged or pre-cancerous cells self-destruct. A large French study linked consuming just 100ml of sugary drinks daily to a 20% increased overall cancer risk. High sugar intake shortens telomeres by the equivalent of 4.6 years of biological aging. Fructose processed in the liver produces lipids that certain tumors consume to build cell membranes. Reducing dietary sugar and refined carbohydrates functions as a direct cancer-prevention strategy.
