The Study
Acetic Acid Influences BRL-3A Cell Lipid Metabolism via the AMPK Signalling Pathway
This study looked at liver cells from rats growing in a dish. It shows that when these cells are treated with acetic acid, certain fat-related chemicals change in a way that might reduce fat buildup. But this doesn't prove it would work the same way in a real animal or person.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
This study looks at how acetic acid, found in vinegar, affects liver cells in a dish. It shows that acetic acid turns on a 'fat-burning switch' and turns off a 'fat-making switch' in rat liver cells.

Key takeaways
Summary
Based on the study abstract and findings.
- 1While the results are from rat cells in a lab, they suggest acetic acid could help reduce liver fat in humans under fasting or low-carb conditions.
- 2In liver cells, 4–8 mM acetic acid reduced fat storage, increased fat-burning genes, and decreased fat-making genes within 1–6 hours.
- 3When the key switch (AMPK) was blocked, these changes didn’t happen.

Acetic acid turns on a key energy sensor in liver cells, which tells the body to start using stored energy.
If you regularly consume something like vinegar (which has acetic acid), it might help your body switch to burning fat faster when you're not eating carbs or during fasting.
Acetic acid helps reduce fat buildup in rat liver cells, and this only happens when a specific energy-sensing pathway (AMPK) is working — if you block that pathway, the effect goes away.
When rat liver cells are treated with a specific amount of sodium acetate, it turns on a key energy-sensing switch in the cells within a few hours.
In liver cells from rats, blocking a key energy sensor called AMPK stops acetic acid from changing fat levels and fat storage — suggesting that acetic acid needs this sensor to work.
Acetic acid might slow down fat-making in rat liver cells by turning off key fat-related genes.
