In recent years, apple cider vinegar has become one of the most prominent trends in the dieting world. On social networks, forums, and various videos, you can find recommendations to drink it on an empty stomach in the morning, based on the belief that it "burns fat", accelerates weight loss, and even cleans the body of toxins. But when examining these claims more deeply, it turns out that reality is not quite as promised to us, and sometimes it is even less pleasant, and even dangerous.
What burns fat in the body: The claim that apple cider vinegar burns fat in the body is not scientifically based. There is no single food that can "melt" fat or cause weight loss without creating a calorie deficit. Fat breakdown processes in the body are controlled by hormones, overall energy balance, and metabolic activity, not by a specific food ingredient consumed at a certain time of day. Therefore, drinking apple cider vinegar in the morning, in the evening, or at any other time does not change the body’s fat-burning mechanism.
Where does the confusion come from: It stems from the fact that apple cider vinegar has some effect on satiety and blood sugar response. A study published in the "European Journal of Clinical Nutrition" showed that adding vinegar to a carbohydrate-rich meal can slow gastric emptying and reduce the rise in glucose and insulin levels after a meal. Again I emphasize - vinegar added to a meal! Not by itself with water.
This means a slightly longer feeling of fullness and a more moderate glycemic response, but it is important to understand that this is only a temporary effect that is not directly related to fat burning. Another important point is the way the vinegar is consumed. In studies, the vinegar was given as part of a meal and not as a drink on an empty stomach. Drinking diluted vinegar with water in the morning, as is commonly recommended on social media, has not been tested under the same conditions, and there is no evidence that it contributes to weight loss.
Damage to the esophagus: Beyond that, uncontrolled consumption of apple cider vinegar may cause health damage, mainly due to its high acidity. Vinegar (any vinegar) contains acetic acid in a high concentration, which can irritate and damage delicate tissues in the digestive system. Regular consumption, especially without sufficient dilution, may cause irritation in the esophagus, a burning sensation in the throat, and even cumulative damage to the mucous membranes.
The teeth are also not immune to this effect. High acidity is known to cause erosion of tooth enamel, an irreversible process that may lead to increased sensitivity and cavities. Daily drinking of vinegar, especially directly or in high concentration, increases this risk.
In addition, there is evidence that vinegar may cause discomfort in the digestive system, especially in people who suffer from stomach sensitivity or conditions such as reflux or ulcers. Studies published in the "American Journal of Clinical Nutrition" and other nutrition journals show that prolonged exposure to high acidity may damage mucosal tissues along the digestive tract, especially when consumption is frequent and without proper dilution.
So although apple cider vinegar is not a "harmful food" in itself, its use as a miracle cure for weight loss is not justified, and may even cause more harm than benefit when consumed incorrectly.
To summarize this unnecessary myth: Ultimately, the path to weight loss remains the same familiar and simpler path than we would like to believe: A balanced diet based on natural foods, a combination of regular physical activity, and mainly creating an appropriate calorie deficit. There are no shortcuts, and there is no single drink that can replace the basic principles of proper nutrition.
The important message is not to completely avoid vinegar, but to understand its place. As a small addition to a meal, it can fit well into the diet, but there is no reason to drink it as a daily beverage in expectation of weight loss.
