The Claim
A 3-week ketogenic diet does not significantly improve hepatic insulin sensitivity in adults with obesity, as measured by insulin-mediated suppression of endogenous glucose production during a hyperinsulinemic-euglycemic clamp, despite reductions in basal glucose production.
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, a three-week ketogenic diet does not increase the liver's ability to respond to insulin by reducing glucose production, even though baseline glucose production decreases.
See the scientific wording
A 3-week ketogenic diet does not significantly improve hepatic insulin sensitivity in adults with obesity, as evidenced by no difference in insulin-mediated suppression of endogenous glucose production during a hyperinsulinemic-euglycemic clamp, despite reduced basal glucose production.
When someone eats very few carbohydrates, the liver stops making as much sugar at rest because it switches to burning ketones for energy instead. But when insulin is present, the liver still doesn't stop making sugar as it should, because the signals that tell the liver to shut down sugar production in response to insulin remain unchanged.
What the research says
1 studyAfter three weeks on a keto diet, obese adults made less sugar in their liver at rest, but their liver still didn’t respond better to insulin when it told the liver to stop making sugar — so the diet didn’t fix the liver’s insulin resistance.
