Sparkling water, a refreshing and often healthier alternative to sugary sodas, may hold more benefits than previously thought—especially for those on a weight loss journey. A recent study published in BMJ Nutrition Prevention & Health suggests that carbonated beverages, like seltzers and sparkling water, might aid in weight loss by promoting glucose uptake and metabolism in red blood cells.
The research builds on earlier findings from Akira Takashi’s 2004 study on hemodialysis, which showed that CO2 in the blood, much like the CO2 in carbonated beverages, can assist in glucose absorption. Takashi’s team theorizes that the carbon dioxide in sparkling water could help weight loss by enhancing glucose metabolism, potentially offering a slight boost to weight management efforts.
However, Takashi cautions that while carbonated water may support weight loss, it shouldn’t be relied upon as a primary strategy. “A balanced diet and regular physical activity remain crucial components of sustainable weight management,” he emphasizes.
How Sparkling Water Might Aid Weight Loss
The study also notes that sparkling water may serve as a natural appetite suppressant. The carbonation can cause distension in the stomach, which leads to feelings of satiety and may reduce hunger. This effect could potentially help control cravings and prevent overeating, making it a useful addition to a weight loss plan.
The Role of Sparkling Water in Your Diet
While sparkling water might provide a small advantage, weight loss results are unlikely to come solely from drinking carbonated beverages. According to weight loss and lifestyle coach Emily Morse, NASM-CPT, the weight loss benefits from carbonated water are minimal but may still help in the process. “When calories are low due to losing weight, having a low-calorie, carbonated drink like sparkling water can be beneficial as it makes the tummy feel ‘full,’” she says. This feeling of fullness can help curb cravings and keep hunger in check.
However, Morse notes that the impact of sparkling water on weight loss is “so small” that it should not be considered a standalone solution. Moreover, some people may experience bloating or discomfort from the carbon dioxide, which could be a downside for those sensitive to fizzy drinks.
Choosing the Right Sparkling Water
When selecting sparkling water, it’s important to choose varieties that are free from added sugars, artificial sweeteners, or unnecessary additives. Registered dietitians recommend brands like Nixie, Bear’s Fruit, Recess, and Waterloo, with Spindrift being particularly favored for its use of real fruit juice and its clean, natural flavor.
For those looking for a more robustly carbonated experience, Hal’s New York Seltzer Water is a top pick, praised for its strong fizz without added sugars.
Conclusion
While sparkling water can be a refreshing, low-calorie beverage that may support your weight loss efforts by promoting satiety, it’s not a magic solution. Staying hydrated—whether with still or sparkling water—is crucial for weight management, but a balanced diet and consistent exercise remain essential for long-term success. Ultimately, it’s about what works best for you and your weight loss journey.
