Apple Cider Vinegar has not shown significant and sustainable weight loss in humans.
One of the most common claims suggests that drinking a small amount of apple cider vinegar before meals or taking an apple cider vinegar supplement helps curb appetite and burn fat. But no studies have been done on a big enough sample group to prove that apple cider vinegar does cause people to lose weight. There is little scientific support for these claims. Studies of apple cider vinegar for weight loss have not consistently shown significant and sustainable weight loss across diverse groups.
