I was sitting with a friend of mine, and she was telling me that she is taking two teaspoons of apple vinegar directly after her meals. She heard that apple vinegar is a fat burner and it accelerates weight loss. Although apple vinegar has never been documented to do anything but add a nice flavor to salad dressings, it has suddenly become a weight loss cure for many people.
Personally, I do not agree with this assessment, because the high acidity of apple cider vinegar can be harmful for the stomach.
Apple cider vinegar is also popular as a natural appetite suppressant, which is why some people consume it before their meals or directly after. One study showed that apple cider vinegar has the ability to delay gastric emptying which is a good thing for normal individuals (not for people suffering from ulcer and reflux).
It increases the satiety feeling, meaning you can stay full for a longer time. This prevents you from eating more, which is possibly one reason that you lose weight. But it does not burn fat. It only delays the feeling of hunger.
There is no substitute for exercise, eating less and lean.
Apple cider vinegar is a natural source of potassium (5mg/serving). It is healthy to cook with it, or have it as a salad dressing, especially to treat mild hypertension.
But … A weight loss miracle? I doubt very much.
