The benefits of apple cider for vinegar are not fully determined. That said, in one 2018 study, overweight adults or those with obesity followed a calorie-restricted diet and drank 2 tablespoons (tbsp) or (30 ml) of vinegar daily. They were compared to a control group of people who didn't consume any vinegar. After 12 weeks, the vinegar group lost more weight than the diet-only group."
