Have you tried every method under the sun to lose weight, but still are unable to find success? The apple cider vinegar diet is a lesser known method of weight loss that has been around since the early 1800s. Like most fad diets, there is little scientific evidence either way, but there are numerous anecdotal reports that attribute significant weight loss to following the apple cider vinegar diet, either alone or in combination with another way of eating such as South Beach or Atkins. The vinegar itself has been used for centuries to cure many ills, and many of its rumored health benefits have been reported by its users.
