Most of the research on apple cider vinegar’s health and weight loss benefits comes from animal studies. These have been promising so far—many show improved metabolism and fat burning—but more testing in humans is needed. So far, human studies haven’t been conducted with large, controlled groups and the positive effects of apple cider vinegar haven’t been shown across diverse groups of people.^{[1]

Many claim that apple cider vinegar can curb your appetite. When you consume apple cider vinegar before a meal as a drink or incorporate it into your food, like in a salad dressing, you’ll feel fuller and eat fewer calories. However, studies show that the largest reason for a suppressed appetite seems to be that the vinegar drinkers were slightly nauseated (the grosser they found the vinegar drink, the less they tended to eat).^{[2]

- There is some evidence that shows apple cider vinegar slows the rate at which food leaves your stomach—AKA, you’re literally fuller for longer.^{[3]

Taking more than 2 tablespoons (30 ml) of vinegar per day can have potentially harmful effects. The main ingredient in vinegar is acid, after all! If you’re unsure how apple cider vinegar will affect you, start by taking 1 teaspoon (4.9 ml) per day to see how you feel.^{[9]

- Enamel erosion on your teeth^{[10]

Apple cider vinegar may cause or worsen gastroparesis in type 1 diabetics. Gastroparesis is the name for delayed stomach emptying, which is a common complication of type 1 diabetes. It makes predicting how long it takes for your blood sugar to rise after a meal difficult, meaning you’ll have problems determining when to take your insulin.^{[12]

The Bottom Line

Apple cider vinegar can help with weight loss, but it isn’t a magic solution. Any approach to weight loss that doesn’t include reduced calorie intake and increased exercise is not guaranteed to help you lose weight or burn fat. Including apple cider vinegar in your diet may help curb your appetite, but think of it as one small piece in a larger weight loss plan.^{[27]

Research source}
- Scientifically, more evidence is needed to support apple cider vinegar as a reliable, long-term method of losing weight.
- Apple cider vinegar is safe to consume in small amounts for most people, but has not been approved as a treatment for any health conditions.^{[28]

Tips

To get the full benefits of apple cider vinegar, purchase unfiltered or undistilled vinegar from a health food store rather than a grocery store. Look for “the mother”—a murky substance at the bottom of the bottle containing a complex structure of acids.^{[29]
