The liver is your metabolic command center—processing nutrients, regulating blood sugar, and managing fat storage. Uniquely, the liver is the only organ that can process fructose. Research by Stanhope showed that fructose-sweetened beverages increase visceral fat. When you consume fructose (from sugar, HFCS, or juice), the liver converts it directly to fat through de novo lipogenesis. Excessive fructose overwhelms the liver, causing fatty liver disease and insulin resistance.
This companion covers the liver’s metabolic role, the fructose problem, why this causes NAFLD, the alcohol parallel, fructose sources, and practical implications for liver health. (4 min read)
