The Claim

Endogenous glucose production during insulin stimulation is suppressed to a lesser degree in men compared to women, and the degree of suppression is correlated with whole-body insulin sensitivity in women but not in men.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

During insulin stimulation, the liver in men releases more glucose than in women, and this difference is linked to how sensitive the body is to insulin in women but not in men.

See the scientific wording

Endogenous glucose production during insulin stimulation is suppressed less effectively in men than in women, and its suppression correlates with whole-body insulin sensitivity in women but not in men, indicating sex-specific differences in hepatic insulin action.

Why this might work

In women, insulin effectively shuts down fat breakdown in fat tissue, keeping fatty acids low, which lets the liver respond properly to insulin and stop making glucose. In men, insulin fails to suppress fat breakdown, so fatty acids flood the liver, blocking insulin’s signal and preventing it from turning off glucose production. This failure only links to overall insulin sensitivity in women because their liver responds cleanly when fat levels are low.

    The study found that in men, the liver doesn’t stop making glucose as well as it should when insulin is high, but in women, it does — and this difference is tied to how sensitive their whole body is to insulin, but only in women.
