Diluted Apple Cider Vinegar Before Meals

American and European folk medicine — vinegar tonics predate the apple cider variety by centuries

Evidence: Modest — meta-analyses show small but real reductions in fasting glucose; NOT a weight-loss tonic

What it is and what it is used for

Apple cider vinegar diluted in water, taken before or with meals. A 2021 meta-analysis of RCTs found it reduced fasting plasma glucose and improved glycemic and lipid parameters — effects real but modest, likely via slowed gastric emptying and carbohydrate absorption. It is not a proven weight-loss aid: the Mayo Clinic states experts have found no meaningful weight loss or long-term hunger control.

Folk history

Vinegar tonics are ancient — Roman soldiers drank posca, water soured with vinegar, on the march. American folk medicine made the apple cider version a cure-all in the 20th century, crediting it with everything from weight loss to 'detox.' The science kept only the smallest of those claims: a genuine, modest nudge to blood sugar.
