The present invention relates to RNAi agents, e.g., double-stranded RNAi agents, targeting the ketohexokinase (KHK) gene, and methods of using such RNAi agents to inhibit expression of KHK and methods of treating subjects having a KHK-associated disorder, e.g., liver disease (e.g., fatty liver, steatohepatitis), dyslipidemia (e.g., hyperlipidemia, high LDL cholesterol, low HDL cholesterol, hypertriglyceridemia, postprandial hypertriglyceridemia), disorders of glycemic control (e.g., insulin resistance, diabetes), cardiovascular disease (e.g., hypertension, endothelial cell dysfunction), kidney disease (e.g., acute kidney disorder, tubular dysfunction, proinflammatory changes to the proximal tubules), metabolic syndrome, adipocyte dysfunction, visceral adipose deposition, obesity, hyperuricemia, gout, eating disorders, and excessive sugar craving.
