Overview
- New reports from German outlets synthesize prior research and emphasize that apple cider vinegar is not a standalone weight‑loss solution.
- AOK warns that the acetic acid content in typical vinegar is too low to support many sweeping health claims.
- Evidence cited includes a 2004 Arizona State University study showing vinegar before carb‑heavy meals can blunt post‑meal blood‑sugar spikes.
- A 2017 University of Tehran trial with 39 participants found appetite‑suppressing effects only when the drink was used within a calorie‑restricted diet, while a 2011 rat study reported cholesterol changes that do not translate directly to humans.
- Safety guidance stresses dilution to protect teeth and the stomach, with practical use limited to small amounts—such as one to two teaspoons in water—as a flavoring or minor aid within dieting or fasting plans.
