"The prominent medical publisher BMJ Group has retracted a study that found apple cider vinegar could help people achieve dramatic weight loss. A press release from the group cited "concerns raised about the quality of the work," as the overarching reason for yanking the March 2024 study, published in the journal BMJ Nutrition, Prevention & Health. The retraction was expected by many nutrition experts, who have long questioned claims that this kind of vinegar could remedy ills including obesity, diabetes, and even cancer."
""Upon first glance, the magnitude of effect for weight loss seemed implausible," says Eric Trexler of Duke University, who was one of the scientists who pointed out flaws in the study just weeks after it was published. The weight loss rivaled what's seen in people taking the latest costly prescription products, like Ozempic and Wegovy. Trexler says he wishes the study had been retracted sooner."
BMJ Group retracted a March 2024 study after a press release cited concerns about the quality of the work. The study enrolled 120 overweight or obese participants in Lebanon and reported that daily doses of apple cider vinegar for 12 weeks produced roughly 9% body-mass loss. The results generated global media attention and lent credibility to claims that apple cider vinegar improves health. Nutrition scientists noted the magnitude of the reported effect seemed implausible and identified methodological flaws. Critics alerted BMJ in June 2024, but more than a year passed before retraction, prompting calls for reforms in academic publishing.
