“Apple cider vinegar helps you lose weight.”
Limited confidence because a few small, short trials report modest weight changes, but the evidence is not reliable enough to establish a meaningful or durable weight-loss effect. A 2025 meta-analysis included a subsequently retracted trial, showed substantial heterogeneity for several outcomes and cannot resolve the uncertainty without an updated analysis.
We do not know whether apple cider vinegar produces meaningful, lasting weight loss. Some short trials report small losses, but the evidence base is limited and one unusually positive trial was retracted.
A short-term change on a scale does not establish a durable weight-management treatment. Study size, duration, diet changes and funding can strongly affect the result.
Safety note: Vinegar is acidic. Drinking it undiluted or exposing teeth to it frequently can irritate the throat and damage tooth enamel.
Talk to a healthcare professional if: Ask a clinician before using concentrated vinegar regularly if you have significant reflux, swallowing problems, delayed stomach emptying or take glucose-lowering medicine.
Apple cider vinegar is not a proven weight-loss treatment. Any real effect appears much smaller and less certain than popular claims suggest.
Treat vinegar as a food ingredient, not the foundation of a weight-loss plan. Put most of your effort into changes you can sustain.

It's a low-risk, low-cost thing to experiment with around a carb-heavy meal, but it won't substitute for the fundamentals of diet quality and consistency, and it should never be taken undiluted.
