The Claim
A 12-week isocaloric low-fat, high-protein, high-fiber diet results in only modest changes in gut microbiota composition in adults with liver or muscle insulin resistance, and is less effective at modulating the gut microbiome than a high-monounsaturated fat diet in this population.
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 insulin resistance in the liver or muscles, a 12-week diet low in fat but high in protein and fiber causes only small changes in gut bacteria compared to a diet high in monounsaturated fats.
See the scientific wording
A 12-week isocaloric low-fat, high-protein, high-fiber diet induces only modest changes in gut microbiota composition in adults with either liver or muscle insulin resistance, suggesting it is less effective than a high-monounsaturated fat diet at modulating the gut microbiome in this population.
Eating more olive oil and similar fats changes the types of bacteria in the gut, which then produce more short-chain fatty acids. These fatty acids trigger the gut to release a hormone that tells the liver to stop making too much sugar and start storing it as glycogen, improving how the liver responds to insulin.
What the research says
1 studyThe study found that eating a diet high in healthy fats like olive oil changed gut bacteria more than eating a low-fat, high-protein diet in people with insulin resistance—especially those with liver issues. So yes, the high-fat diet worked better for gut bacteria.
