Apple Cider Vinegar May Boost Weight Loss, Study Says

A new study found that people who drank 10 to 15 ml of apple cider vinegar per day lost an average of 15 pounds in 12 weeks.

While many health trends may be a bust or a fad, science has found that apple cider vinegar benefits may actually be true.

In a double-blind, randomized clinical trial published in BMJ Nutrition, Prevention, and Health, scientists recruited 120 Lebanese individuals with high BMIs or obesity to investigate whether apple cider vinegar could promote weight loss.


The research team divided the participants into four groups. Over 12 weeks, three groups consumed either 5, 10, or 15 ml of apple cider vinegar — consisting of 5% acetic acid diluted in 250 ml of water — once a day, first thing in the morning before breakfast. The fourth group received a placebo liquid throughout the study period.

The participants recorded their food intake and daily physical activity during the trial. They also underwent tests to determine their fasting blood glucose, triglyceride, and cholesterol levels at the study's onset and again at weeks four, eight, and 12.

After 12 weeks, the scientists found that, depending on the dose, those who drank apple cider vinegar once daily lost an average of 13 to nearly 18 pounds and reduced their body mass index (BMI) by 2.7 to 3 points.

Specifically, participants who consumed 5 ml per day lost an average of 11 pounds, while those who drank 10 to 15 ml daily experienced an average weight reduction of 15 pounds after 12 weeks.

In contrast, individuals in the placebo group lost around one pound and showed almost no reduction in BMI.

Participants who drank apple cider vinegar also experienced reductions in serum glucose, triglycerides, and cholesterol.

"It is important to note that the diet diary and physical activity did not differ among the three treatment groups and the placebo throughout the whole study, suggesting that the decrease in anthropometric and biochemical parameters was caused by apple cider vinegar intake," the study's authors wrote.

The researchers note that participants drinking apple cider vinegar did not experience side effects, so it could be a promising supplement for weight loss.


Still, they say the 12-week study period wasn't long enough to determine long-term effects. Moreover, because the study only recruited 120 people, more research is needed using a larger number of participants to determine whether the results are similar among the general population.

In addition, because it's acidic, apple cider vinegar can harm the teeth and throat if not diluted with water or other liquids. It can also be hard on the stomach when taken without food and lower potassium levels in the body. Therefore, like with any supplement, it's best to consult a healthcare provider before adding apple cider vinegar to your diet.
