The Claim

In mice fed a high-fat diet, intragastric administration of 0.3% or 1.5% acetic acid over a 6-week period is associated with reduced accumulation of body fat and liver lipids, with no observed changes in food intake or skeletal muscle weight, suggesting a metabolic effect independent of caloric intake or muscle mass.

Source: Acetic acid upregulates the expression of genes for fatty acid oxidation enzymes in liver to suppress body fat accumulation.

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

Giving mice vinegar (acetic acid) in their stomachs while they eat fatty food seems to help them store less fat in their bodies and livers, even if they eat the same amount and don’t gain or lose muscle.

See the scientific wording

In mice fed a high-fat diet, intragastric administration of 0.3% or 1.5% acetic acid for 6 weeks is associated with reduced accumulation of body fat and liver lipids, despite no changes in food intake or skeletal muscle weight, suggesting a metabolic effect independent of caloric intake or muscle mass.

What the research says

1 study
  1. Study: Acetic acid upregulates the expression of genes for fatty acid oxidation enzymes in liver to suppress body fat accumulation.

    The study gave mice acetic acid while they ate a high-fat diet and found they stored less fat in their bodies and livers, even though they ate the same amount of food. This matches the claim exactly.
