There is a lot of information on the Internet about the effectiveness of apple cider vinegar for weight loss, but the evidence base for such "recommendations" is extremely small.
Research on rodents
showed that acetic acid can actually affect the breakdown of fats and prevent their accumulation. But the results of animal studies are not enough to consider them a call to action.
A small study involving volunteers found out the effect of vinegar on suppressing appetite and reducing the amount of food consumed. Those who consumed vinegar did eat less.
But in fact, a decrease in appetite was associated with nausea caused by vinegar.
The most cited study concerns the effect of vinegar on weight loss. Japanese scientists gathered 155 overweight people. They were divided into three groups and offered to drink 500 milliliters of fluid per day. The first group added 15 milliliters of vinegar to the liquid, the second 30 milliliters, the third received a placebo.
Three months later, those study participants who drank water with vinegar lost a little weight: the first group an average of 1.2 kilograms, the second group - 1.9 kilograms.
However, the researchers themselves reported the calorie content of their diet - their results may be inaccurate. In addition, the study was published in 2009, and since then these results have not been reproduced.
And no study has studied the effect of apple cider vinegar directly on the body.
