The Claim
In humans with nonalcoholic fatty liver disease, hepatic acetyl-CoA production via β-oxidation is not reduced compared to healthy controls, but its metabolic fate shifts from ketogenesis to oxidation in the TCA cycle, resulting in increased hepatic oxygen consumption and gluconeogenesis despite similar substrate availability.
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 nonalcoholic fatty liver disease, the liver produces the same amount of acetyl-CoA from fat breakdown as in healthy people, but it uses that acetyl-CoA differently—burning it in the TCA cycle instead of making ketones, which increases oxygen use and glucose production.
See the scientific wording
In humans with nonalcoholic fatty liver disease, hepatic acetyl-CoA production via β-oxidation is not reduced compared to healthy controls, but its metabolic fate shifts from ketogenesis to oxidation in the TCA cycle, resulting in increased hepatic oxygen consumption and gluconeogenesis despite similar substrate availability.
In fatty liver, the liver breaks down fat at the same rate as a healthy liver, but instead of turning the fat breakdown products into ketones for energy, it forces them into a different pathway that makes more sugar and uses more oxygen to do it. This extra sugar production raises blood glucose 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 breaks down fat just as much as healthy people, but instead of making ketones for energy, it uses that fat to make more sugar and uses more oxygen to do it.
