I wanted to write about this topic because it seems like this claim is everywhere. I used to work for a nutritionist that would tell his clients to do this. When I googled that question, several different websites came up. When I typed this into the National Clinical Biotechnology Information website, which is where I can find peer reviewed, researched (in other words, legit) articles, I was unable to find anything about the connection between vinegar and weight loss. I did find several peer reviewd, older articles (circa 2005, 2006 and 2007) that demonstrated that vinegar can help lower blood glucose levels slightly, help kill bacteria, lower cholesterol, but nothing about it burning fat.
My nutrition practice and philosophy is based more so on evidence based nutrition, (meaning nutrition claims that are backed up with peer reviewed research studies), however I do recognize that some things seem to work and don’t have a study to back them up. After a little more digging, I found what I thought was a good article on this topic. The author states that, “Studies suggest that vinegar can increase feelings of fullness and help people eat fewer calories, which can lead to weight loss.” 1
So to answer the question, Does apple cider vinegar burn fat? It’s not the vinegar itself, but rather the fact that it can contribute to feeling full and consuming less calories.
