Could your favorite fizzy drink be a secret weapon for weight loss? New research offers insights into sparkling water’s potential benefits.

A report published in BMJ Nutrition, Prevention & Health compared how carbon dioxide affects blood glucose by examining carbonated water consumption and hemodialysis treatments (a type of dialysis). The results showed that when CO2 entered the bloodstream, glucose levels dropped from 118.3 to 98.6 mg/dL, suggesting potential metabolic benefits.

However, the study notes: “The amount is so small that it is difficult to expect weight loss effects solely from the CO2 in carbonated water.”

But before you feel deflated, there are other ways sparkling water could support your weight loss goals, according to the Cleveland Clinic. The bubbles can help you feel fuller, potentially reducing unnecessary snacking between meals. Plus, it can be used to help kick a sugary soda addiction.

“It can be difficult to transition from sweet drinks to water, but flavored seltzers and sparkling water can help,” registered dietitian Lauren Sullivan told the Clinic. “Water, whether plain or carbonated, is better than high-calorie, sugar-infused drinks.” Just keep in mind, not all sparkling waters are created equal. Skip varieties with added sugars, artificial sweeteners or high sodium levels.

To achieve even greater weight loss, Dr. Josh Kaplan, founder and CEO of Dr. Well by BuildMyHealth, recommends incorporating sparkling water into a broader plan that includes consistent physical activity, a balanced diet, adequate sleep, effective stress management and proper hydration, Healthline reported.

“Drinking fizzy water is just part of the equation for effective weight loss,” explained Kaplan. “It could be used as an alternative to high-calorie drinks, but to achieve real progress, it must be used in conjunction with diet and exercise.”

While sparkling water isn’t a miracle weight loss solution, research suggests it can be a valuable tool in your health journey — especially when combined with healthy lifestyle habits.
