Drinking vinegar alone will not make an individual lose weight, although it may help individuals on a balanced weight-loss program by reducing appetite and lowering blood sugar levels. A medical study conducted in 2009 suggested that vinegar may help to slow weight gain.
Proponents of vinegar use assert that it provides many benefits. Apple cider vinegar is the most popular vinegar for weight loss and other health benefits. Ingesting vinegar may increase feelings of fullness and lead to reduced calorie intake. Vinegar is an antimicrobial and can kill certain strains of bacteria. Vinegar has been proven to lower blood sugar levels and improve insulin sensitivity. Apple cider vinegar may be useful for those with diabetes. However, those that suffer from diabetes and are prescribed medicine to lower blood sugar should check with their physician before using apple cider vinegar.
The Mayo Clinic asserts that while apple cider vinegar is used by many for weight loss, effects are not proven and overconsumption of vinegar is unhealthy. Vinegar is highly acidic and may irritate the throat if too much is consumed, or if it is consumed in large amounts. Vinegar may also interact with supplements and drugs such as diuretics and insulin, resulting in low potassium levels. Health experts at the Mayo Clinic suggest that the healthiest way to lose weight is to exercise and reduce caloric intake.
