Daily ingestion of vinegar with 5% acetic acid can result in weight loss, according to a study conducted by Tomoo Kondo from Mizkan Group Corporation in Aichi, Japan and colleagues.
Early studies have already shown that ingestion of acetic acid the main active ingredient in vinegar suppresses body fat accumulation in animals. The current study proved that acetic acid works also for human body to help weight loss.
Three groups of obese subjects with similar body weight, body mass index, and weight circumference were told to drink daily 500 ml of a beverage with 30 ml, or 15 ml, or zero ml of a vinegar. 30 ml of vinegar contains 1.6 grams acetic acid which is common in all sorts of vinegar. The trial lasted three months.
All measured parameters including body weight, body mass index, visceral fat, waist circumference, and serum triglyceride levels were significantly lower in the two groups ingesting vinegar. Those who drank 30 ml of vinegar during the treatment lost about 6.5 lbs of body weight.
The authors concluded that “daily intake of vinegar might be useful in the prevention of metabolic syndrome by reducing obesity.”
Acetic acid is known to provide a range of benefits. It can help weight loss, diabetes, heart disease, or even cancer.
Caution: Undiluted vinegar with 5% acetic acid can be too strong for most people. It should be diluted with water before ingested. Acetic acid is highly erosive and can damage tooth easily. So you should not drink undiluted vinegar.
