The Claim

Genetic deletion of Nfil3 in mice fed a high-fat diet reduces weight gain, hepatic steatosis, glucose intolerance, and intestinal permeability.

Source: Nfil3 integrates circadian rhythm and microbial metabolite signaling to maintain gut–liver immune–metabolic homeostasis under high-fat diet stress

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In mice on a high-fat diet, removing the Nfil3 gene results in less weight gain, less fat accumulation in the liver, lower blood sugar levels, and reduced leakage in the intestine.

See the scientific wording

In mice fed a high-fat diet, genetic deletion of Nfil3 reduces weight gain, hepatic steatosis, glucose intolerance, and intestinal permeability, suggesting Nfil3 plays a key role in mediating metabolic dysfunction under dietary stress.

Why this might work

When the gut microbiome is disrupted by a high-fat diet, it produces fewer beneficial chemicals that keep the gut lining tight and calm the immune system. This allows harmful bacterial parts to leak into the liver, triggering inflammation and turning on a gene called Nfil3. Nfil3 shuts down the body’s internal clock that controls when fat and sugar are processed, causing the liver to store too much fat and the body to struggle with blood sugar. Nfil3 also blocks the production of protective mucus in the gut and shifts immune cells in the liver toward a pro-inflammatory state, worsening liver damage and metabolic dysfunction.

    When mice that can't make the Nfil3 protein eat a high-fat diet, they get fatter, have worse livers, and handle sugar poorly — but not as badly as normal mice. This means Nfil3 makes the damage from bad food worse.
