A recent study from Japan suggests that sparkling water may assist in weight loss by promoting a feeling of fullness and boosting metabolism. The findings, published in the journal BMJ Nutrition, highlight the benefits of consuming carbonated beverages in dietary regimens.
Dr. Akira Takahashi, director of a dialysis center in Shijonawate, explains that the carbon dioxide in sparkling water acts similarly to a dialysis treatment, which cleanses the blood in cases of renal dysfunction. During dialysis, carbon dioxide enters the bloodstream, creating a bicarbonate solution that alters the blood's pH, facilitating glucose metabolism.
This process may contribute to weight loss by promoting the consumption of glucose present in the bloodstream after drinking sparkling water. However, the study notes that the effects are minimal; for instance, a four-hour dialysis session consumes approximately 9.5 grams of glucose, indicating that significant amounts of sparkling water would be necessary for noticeable effects.
Experts caution against relying solely on sparkling water for weight loss, as excessive consumption could lead to health issues. They recommend a daily intake of two liters of water, which is considered adequate. While the weight-loss potential of sparkling water is limited, it may serve as a supplementary aid alongside regular physical activity and a medically supervised diet.
