After 12 weeks of consumption, vinegar significantly reduced waist circumference, visceral (abdominal) fat, and body weight, in comparison with the placebo. This study supports use of apple cider vinegar in prevention of metabolic diseases, by reducing obesity.1 Another study, in healthy subjects, demonstrated that vinegar intake may increase satiety, and, thus, prevent weight gain. The same study showed that vinegar, when added to high-glycemic load meals reduced the postprandial glycaemia.2
