Apple cider vinegar is known to have fat-burning properties, so much so that it is the protagonist of a diet of apple cider vinegar (here) and some “slimming” drinks or supplements: but are these properties real or presumed? Glamor magazine has decided to find out if apple cider vinegar for weight loss works or is just commonplace by interviewing some dieticians. Here’s what came out. 
Does apple cider vinegar for weight loss work? Apparently yes, if taken immediately before, during or immediately after meals : however, these are modest results, and not such a fat-dissolving effect that we can think of relying only on this trick to lose weight.
In short, it is not a miracle remedy, but it does something.

The reason for its mild but still effective action to lose weight is simple: apple cider vinegar inhibits the activity of some enzymes that digest carbohydrate starch, making it less assimilable even in caloric terms, and it would also facilitate the digestion of proteins. and digestion in general. According to a Japanese study published in 2009 , using apple cider vinegar on a daily basis would also help lower triglycerides and body fat percentage: scientists have found that drinking from one and a half to three tablespoons a day of vinegar dissolved in 500 ml of water or other beverage, obese people lost fat mass and body weight. The credit would be acetic acid, so those who do not want or cannot use apple cider vinegar for weight loss can also try wine vinegar.
How much have the Japanese patients lost? From one to two kilos in three months, but without going on a diet. 
In short, a modest result, perhaps useful for those who already have a balanced diet.
How to take it? I suggest a teaspoon of apple cider vinegar or wine vinegar in two fingers of water during each main meal, at the beginning of the meal, but be warned: for those suffering from stomach acid and gastroesophageal reflux, the apple cider vinegar trick does not it is certain to recommend. Furthermore, in order to avoid esophageal problems, tooth erosion and stomach problems, it is better not to exceed the dose of a diluted teaspoon, and to take a treatment of 12 weeks maximum, then stop for 4-8 weeks and resume.
