My friend says she drinks apple cider vinegar at bedtime to help her eat less and lose weight. Could it work?
A. Scientific evidence doesn't support drinking apple cider vinegar to dampen appetite or help with weight loss. But even on a commonsense level, it's not likely. Here's why: changing only a single part of our routine — such as drinking a shot of apple cider vinegar each evening — can't help us shed excess pounds as effectively as broader efforts that include changing our overall diet and exercising more often.
Beyond that, apple cider vinegar's high acidity level makes bedtime a less-than-ideal time to drink it. Anyone prone to heartburn or gastroesophageal reflux disease (GERD) should avoid eating or drinking anything acidic at least 30 to 60 minutes before sleep to lessen the odds of uncomfortable burning in the chest. Over time, drinking undiluted vinegar can also erode your tooth enamel.
People who still want to consume apple cider vinegar can do it more safely and comfortably if they mix a small amount into a large glass of water or combine it with other ingredients in salad dressings.
