The Claim
A 3-week ketogenic diet reduces basal endogenous glucose production by approximately 21% in adults with obesity, independent of changes in hepatic insulin sensitivity, indicating a shift in hepatic fuel utilization toward ketone bodies.
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 adults with obesity, following a ketogenic diet for three weeks lowers the liver's natural production of glucose by about 21%, and this happens without improving how the liver responds to insulin, suggesting the liver starts using ketone bodies instead of glucose for energy.
See the scientific wording
A 3-week ketogenic diet reduces basal endogenous glucose production by approximately 21% in adults with obesity, independent of changes in hepatic insulin sensitivity, suggesting a shift in hepatic fuel utilization toward ketone bodies rather than improved insulin action.
When the body runs on ketones instead of glucose, the liver stops making as much glucose because it no longer needs to supply energy to other tissues. The liver switches to burning ketones for its own energy and lets other tissues use ketones too, so there is no need to produce glucose from scratch.
What the research says
1 studyAfter three weeks of a keto diet, the liver of obese adults made 21% less glucose while resting, even though insulin didn’t work any better on the liver. This suggests the body switched to using ketones for energy instead of glucose.
