The claim
Drink apple cider vinegar daily to burn fat. Morning shots. Bedtime drinks. Gummies. The internet sells ACV as a fat-burning staple, and the claim has run for years.
The study that made it famous got retracted
The widely publicized 2024 weight-loss trial behind the fad was later retracted (retraction notice). Retraction removes a study from the evidence base. The single biggest pillar of the ACV weight-loss claim no longer stands.
What the remaining evidence shows
Small trials show, at most, small short-term effects on weight and blood sugar. The studies have quality concerns and inconsistent replication. Mayo Clinic states that meaningful or lasting weight loss has not been established. What remains is a folk remedy with no established effect on real weight loss.
What works instead
The honest answer has no vinegar in it. Sustained diet changes. Regular activity. For people who qualify, GLP-1 medicines under medical supervision have the strongest drug evidence. Our gelatin trick guide lays out the trial numbers.

Questions, answered
Does apple cider vinegar burn fat?
No established effect. Weak trials show small short-term signals at most. Mayo Clinic says lasting weight loss is not established.
What happened to the 2024 study?
It was retracted. Claims built on it lost their main support. That is how science corrects itself, and it is worth respecting.
Are ACV gummies any better?
No. They are candy with vinegar branding. Same weak evidence, plus sugar.
