At my annual physical last year my liver enzymes (ALT/AST) were elevated and an ultrasound showed "mild to moderate hepatic steatosis" — fatty liver disease, or NAFLD. My doctor said the main treatment was weight loss and avoiding alcohol (I barely drink). Six months of keto later, I just got a follow-up ultrasound and my doctor said the fatty liver is "essentially resolved" and my liver enzymes are back to normal range. I want to share this because NAFLD is apparently extremely common and I had no idea keto specifically helps with it.
Keto reversed my fatty liver — the diagnosis nobody talks about

NAFLD (non-alcoholic fatty liver disease) is one of the most common chronic liver conditions — estimated 24% of the global adult population has it, most are undiagnosed. Your story is important because it's more common than most people realize and keto is one of the most effective dietary interventions available.
Why keto specifically reverses fatty liver:
NAFLD is largely driven by excess dietary carbohydrate, particularly fructose and refined carbohydrates, which the liver converts to fat (de novo lipogenesis). This is actually where "fatty liver" comes from — not from eating fat, but from the liver converting excess carbohydrates into fat that accumulates in liver cells.
Keto eliminates both refined carbohydrates and fructose (from fruit and sugar). Without this flood of carbohydrate-derived fat synthesis, the liver can clear existing fat deposits. Additionally, ketosis increases fatty acid oxidation — the liver burns fat. The combination of less fat production + more fat burning reduces hepatic steatosis relatively quickly.
Multiple studies show 3-6 months of ketogenic diet reduces liver fat by 50-70% in NAFLD patients. Your experience of "essentially resolved" in 6 months is consistent with the published literature.
My liver enzymes were also elevated at my keto start — ALT was 67 (normal upper range 40). At my 6-month follow-up it was 28. My doctor noted it without much comment but I know from reading that ALT normalization in fatty liver is a significant finding.
The "fat causes fatty liver" misconception is so deeply embedded that people are shocked to hear dietary fat doesn't cause NAFLD — excess carbohydrate and sugar does. Keto is essentially the opposite of what one would intuitively expect to fix fatty liver, which is why your story is valuable to share.
NAFLD is also strongly linked to insulin resistance and metabolic syndrome. Keto addresses all of these simultaneously — it's a holistic metabolic intervention, not just a diet. Improving insulin sensitivity, reducing liver fat, normalizing blood sugar, improving lipids — these are all interconnected and keto addresses the upstream cause (excess carbohydrate and insulin) rather than individual symptoms.
This should be in every fatty liver discussion thread online. My husband was diagnosed with NAFLD and told to "eat healthy and exercise more" — the standard advice that had him eating whole grains and low-fat yogurt, which do nothing to address the actual cause. After reading your post and similar stories, he started keto 4 months ago. His liver enzymes at his last check were normal for the first time in 5 years.
The "it's not from eating fat" explanation was genuinely shocking to me when I first understood it. I had a fatty liver and was eating low fat, avoiding eggs, limiting butter — exactly backwards. The metabolic science being the opposite of conventional wisdom is frustrating but also liberating when you understand it. Thank you all for the additional context and mechanism explanation.
