Apple cider vinegar: Katy Perry and Victoria Beckham swear by it, but health experts are not convinced
- Drinking apple cider vinegar regularly keeps blood sugar levels stable, and helps with weight loss and reducing sugar cravings, recent studies have found
- Despite these results, doctors still can’t come to a definitive conclusion about how effective it really is

The drink that celebrities such as Beyoncé, Jennifer Aniston and Gwyneth Paltrow start the day with isn’t coffee; it’s lemon water, a simple concoction of warm water and fresh lemon juice.
Besides flooding the body with immunity-boosting vitamin C, drinking warm lemon water on an empty stomach is said to aid digestion, improve the skin, maintain the body’s pH level and reduce inflammation.
But how valid are these claims? According to one short-term Japanese study, published in 2009 in the journal Bioscience, Biotechnology and Biochemistry, drinking ACV was shown to help with weight loss.

Overweight men and women consumed 15ml of the vinegar mixed with 250ml of water twice a day as part of their regular diet. After 12 weeks, the participants each lost about one kilogram, although once they stopped drinking the diluted ACV, their weight returned to usual levels within four weeks.
