Apple cider vinegar for weight loss: Does it work?

I've read that a tablespoon of apple cider vinegar taken before meals increases metabolism. Is this true?

- No name / No state given

Mayo Clinic dietitian Katherine Zeratsky, R.D., L.D., and colleagues answer select questions from readers.

Answer

There is no evidence that taking apple cider vinegar for weight loss is effective.

Proponents of the apple cider vinegar diet claim that drinking a tablespoon (or more) of apple cider vinegar before meals or taking an apple cider vinegar supplement will help curb your appetite, reduce cravings and burn more fat. However, none of these claims has been proved.

In fact, apple cider vinegar has a very high acid content that may be irritating to your throat when consumed frequently or in large quantities. Apple cider vinegar also may interact with certain drugs, including diuretics, increasing your risk of potassium loss.

Fad diets, such as drinking apple cider vinegar for weight loss, may promise quick or easy results — but there's no "magic diet" that will peel off the pounds. When it comes to losing weight, your best bet is still a healthy, low-calorie diet combined with regular exercise.
