The Claim
In individuals with nonalcoholic fatty liver disease (NAFLD) and hepatic triglyceride content ranging from 5% to 52%, impaired ketogenesis during a 24-hour fast is associated with increased acetyl-CoA oxidation in the TCA cycle, elevated hepatic oxygen consumption, and higher rates of gluconeogenesis and plasma glucose concentrations, indicating that altered acetyl-CoA partitioning—not acetyl-CoA production—drives hyperglycemia in fatty liver.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with fatty liver and moderate to high liver fat, a 24-hour fast leads to reduced ketone production, which coincides with increased use of acetyl-CoA in the energy cycle, higher oxygen use in the liver, and greater glucose production and blood sugar levels, showing that how acetyl-CoA is directed within liver cells—not how much is made—causes elevated blood glucose.

In fatty liver, the liver stops making ketones during fasting and instead burns fat for energy in a way that produces more sugar. This happens because the fat breakdown products get used in a different pathway that requires more oxygen and builds sugar from scratch, which raises blood sugar levels.
What the research says
1 studyStudy: Impaired ketogenesis and increased acetyl-CoA oxidation promote hyperglycemia in human fatty liver.
In people with fatty liver, their liver stops making ketones during fasting and instead burns fat for energy in a way that uses more oxygen and makes more sugar, which raises blood sugar levels. This happens because the liver changes how it uses fat, not because it makes more fat.
