Why fat around your belly might hurt your liver
SIRT1 Transcription Is Decreased in Visceral Adipose Tissue of Morbidly Obese Patients with Severe Hepatic Steatosis

When you have too much belly fat, your body may stop making enough SIRT1 protein in that fat, which helps your liver stay healthy. Less SIRT1 means more fat builds up in the liver and your body becomes less able to use insulin properly.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

In very overweight people, only the fat around the organs (not the fat under the skin or back) shows lower levels of a protective gene (SIRT1) when the liver is very fatty — suggesting belly fat is uniquely involved.
In very overweight people, other genes known to affect fat and liver health didn’t change between those with mild and severe fatty liver — only SIRT1 did, making it stand out as a possible key player.
Chronic exposure of the liver to visceral adipose-derived free fatty acids and cytokines induces hepatic steatosis, elevates serum triglycerides, increases blood pressure, and promotes systemic insulin resistance.
In very overweight people, those with the worst fatty liver also had much lower levels of a specific gene (SIRT1) in their belly fat, which might mean this gene helps protect the liver from too much fat.
In very overweight people with severe fatty liver, the less SIRT1 gene activity they have in their belly fat, the worse their body’s response to insulin tends to be — meaning their blood sugar control is poorer.
