The research draws parallels between the effects of fizzy water and the haemodialysis process, where only a minimal amount of glucose is utilized, indicating that the impact of carbonated water on weight loss is limited.

This effect could be particularly beneficial for individuals struggling with hunger, as carbonated water may enhance feelings of fullness by prolonging food retention in the stomach.

Experts affirm that while drinking plain sparkling water is generally safe and promotes hydration, it may cause digestive issues for some.

Ultimately, for effective weight management, the NHS recommends a balanced diet and regular physical activity, with fizzy water serving only as a minor supporting factor.

A recent study published in BMJ Nutrition, Prevention & Health suggests that carbonated water may have a minor impact on blood sugar levels, potentially aiding in weight loss.

However, experts like Professor Sumantra Ray caution that there is insufficient evidence to recommend carbonated water specifically for glucose metabolism, highlighting the need for further research.

The potential benefits of carbonated water must be balanced with possible harms, particularly if the beverages contain sodium, glucose, or other additives.

In fact, during dialysis, only about 9.5 grams of sugar is used after processing a large volume of blood, underscoring the negligible effect of carbonated beverages.

Despite these findings, the study indicates that carbonated beverages can act as appetite suppressants by creating gastric distension, which may lead to increased feelings of satiety.

Nevertheless, some individuals, especially those with sensitive stomachs or conditions like GERD, may experience discomfort such as bloating and gas from consuming sparkling water.

Additionally, the acidic nature of sparkling water raises concerns about dental health, as it can weaken tooth enamel, although it is less harmful than sugary drinks.

In conclusion, while there may be some metabolic benefits to carbonated water, it should not be relied upon as a primary tool for weight loss.
