The apple cider vinegar diet involves adding apple cider vinegar to an otherwise healthy diet and is based on the premise that apple cider vinegar speeds up the body's ability to retrieve nutrients from and break down fats and proteins quickly and efficiency, which in turn speeds up metabolism, according to Healthline. In addition, apple cider vinegar contains pectin, which is thought to give a sense of satiety after eating, which works to lower the chance of overeating or compulsive eating. However, not all experts recommend the diet, while some say its effects on weight loss are minimal at best.
Among members of the medical community, belief in apple cider vinegar for use in weight loss and the apple cider vinegar diet is low, notes Healthline. Some experts say that apple cider vinegar does not likely affect weight loss or burn fat, while others say there is no convincing evidence of apple cider vinegar's effect on metabolism.
One 2014 study found that there is some evidence that vinegar in general can help with obesity and hyperglycemia, however, reports Healthline. It may help with maintaining the body's pH level, including both acidity and alkalinity, and in some studies, apple cider vinegar helped to manage post meal blood sugar levels. It is also a good supplement or topical ingredient for improved skin health.
