Does apple cider Vinegar can help weight loss? Apple cider vinegar is a type of vinegar made by the fermentation of apple cider. During this process, sugar in the apple cider is broken down by bacteria and yeast into alcohol and then into vinegar. Apple cider vinegar contains acetic acid (like other types of vinegar) and some lactic, citric and malic acids. It’s yet to be determined if the benefits of apple cider vinegar are worthwhile for weight loss. Even still, some suggest that the acidity of the vinegar mixed with the pectin found in apples can offer an easy answer to dropping pounds.
