Fizzy water might give a small boost to glucose metabolism, which can support weight loss. However, this effect is too minor to rely on without proper diet and exercise.
Sparkling Water and Weight Loss
A study published in BMJ Nutrition, Prevention & Health suggests that carbonated water could enhance glucose metabolism slightly. This process helps the body convert energy. But the impact is minimal, and sparkling water alone is not enough for weight loss.
Experts emphasize that the best way to manage weight is through regular exercise and a balanced diet. Overconsuming fizzy water might also lead to digestive discomfort, and its long-term effects are still unclear.
How Does It Work?
Sparkling water may:
- Create a feeling of fullness, reducing hunger.
- Speed up digestion.
- Lower blood glucose levels slightly.
Researchers found similarities between how the body processes fizzy water and hemodialysis, where blood is filtered and glucose levels drop slightly.
During hemodialysis, carbon dioxide (CO2) is absorbed and converted to bicarbonate (HCO3), which activates enzymes that help glucose absorption. But even in hemodialysis, the glucose reduction is small, making the effect of carbonated water negligible for weight loss.
Expert Opinions
Drinking sparkling water may indirectly support metabolism, but it’s not a substitute for healthy habits. Side effects like bloating and gas can occur, especially for those with sensitive stomachs or conditions like IBS or acid reflux.
Professor Sumantra Ray of the NNEdPro Global Institute says more research is needed to confirm these benefits. He stresses moderation and warns against overconsumption of fizzy drinks containing additives like sodium or sugar.
Final Takeaway
Enjoy sparkling water in moderation, but focus on balanced meals and exercise for sustainable weight management.
