Dr Deborah Lee explains: “In 2009, one Japanese randomised controlled trial reported some favourable results about the dietary intake of vinegar on weight loss. In this study, the vinegar used was apple cider vinegar.
“Over a 12-week period, 155 obese participants (BMI 25-30) were divided into 3 groups – vinegar 15 ml per day, vinegar 30 ml per day, or no vinegar.
“By week 4, reductions in BMI and Body Fat Ratio (BFR) was seen to decrease in the vinegar group. By 12 weeks this was statistically significant. Waist circumference and, waist-hip ratio, and blood levels of triglycerides all started to decrease from week 8.
“Over the study period, those drinking daily vinegar had a reduction in body weight between 1-2 kg.

“Vinegar – otherwise known as acetic acid – directly inhibits specific genes responsible for fat synthesis and also down-regulates various genes associated with the production of triglycerides. It also stimulates the oxidation (breakdown) of free fatty acids.
Dr Lee explains the vinegar should always be diluted.
She says: “If drunk neat it has been shown to cause caustic burns in the oesophagus.
“There have been rare case reports of low potassium levels in people who drink excessive amounts of vinegar.
Apple cider vinegar’s benefits exceed weight loss and can help lower cholesterol and help regulate blood sugar levels after meals.
However some people aren’t convinced that apple cider vinegar does help lose you lose weight and those taking it should be mindful of the risks.
Tara Gadre, co-founder of gym Strength House and Wellbeing Contributor at Tictrac commented: ““Apple cider vinegar is often touted as a method for weight loss, but there is actually little scientific research to support this claim. Previous studies have shown that administering acetic acid, which is found in apple cider vinegar, could potentially increase fatty acid oxidation, however, more research is necessary before claims of weight loss can be made.
“The main component of weight loss is understanding energy balance by creating a calorie deficit, so while apple cider vinegar may be great as a salad dressing, understanding this principle and seeking help and support from a professional nutritionist or dietician is the best way to lose weight.”
A calorie deficit is when you are burning more calories than you are consuming. This inevitably helps you lose weight because you are eating less food and less calories. Your calorie deficit can be increased with regular exercise and healthy foods.
