Fat in the liver blocks the body’s ability to manage blood sugar, making it harder to lose weight anywhere else.
Scientific Claim
Hepatic lipid accumulation impairs insulin signaling and glucose metabolism, acting as a primary driver of systemic insulin resistance.
Original Statement
“liver fat dropped significantly as well. Okay? And that matters because liver fat is one of the strongest drivers of insulin resistance. So think of liver fat like sort of a traffic jam inside your metabolism. When fat accumulates in the liver, glucose handling breaks down. insulin signaling gets sloppy and fat loss everywhere else becomes harder.”

Evidence from Studies
Supporting (1)
The mitochondrial-derived peptide MOTS-c promotes metabolic homeostasis and reduces obesity and insulin resistance
This study found that a molecule from mitochondria can fix insulin resistance without touching liver fat, meaning liver fat isn’t the only or main cause of insulin problems.
Contradicting (4)
This study is about why some babies in Tanzania don't get their vaccines on time, not about how fat in the liver affects blood sugar or insulin.
Tesamorelin improves fat quality independent of changes in fat quantity
This study looked at how fat quality changed in the belly and under the skin after a drug treatment, but it didn’t check the liver or how well insulin works in the body, so it doesn’t tell us if liver fat causes insulin problems.
The Growth Hormone Releasing Hormone Analogue, Tesamorelin, Decreases Muscle Fat and Increases Muscle Area in Adults with HIV
This study looked at how a drug improved muscle quality in people with HIV, but it didn’t check the liver or how the body responds to insulin, so it doesn’t tell us whether fat in the liver causes insulin problems.
286-OR: Spatial Regulation of Glucose and Lipid Metabolism by Hepatic Insulin Signaling
The study found that even when the liver had less fat, blood sugar was still high and insulin wasn’t working right — meaning fat in the liver isn’t the main cause of insulin resistance.
