Acetic-acid

Apple cider vinegar has one well-replicated effect relevant to weight management: modest post-meal blood glucose blunting via acetic acid. A single Japanese RCT found 0.75–1.2 kg more weight loss over 12 weeks with daily ACV. Evidence is real but modest. Safety considerations (tooth enamel, oesophageal irritation) are clinically important.

Apple cider vinegar is one of the most widely used 'natural' weight loss supplements. This article examines the clinical evidence for its effects on weight, blood glucose, and appetite, its safety profile, and how its evidence compares to other interventions.
