In the quest for healthier alternatives to sugary drinks, sparkling water has emerged as a popular choice. Also known as carbonated water, it is infused with carbon dioxide gas under pressure, creating its characteristic bubbly texture. But is sparkling water truly beneficial for weight loss, or is it simply a passing trend?
The Importance of Hydration in Weight Loss
Before exploring the specifics of sparkling water, it's crucial to understand the vital role hydration plays in weight management. Adequate water intake is essential for various bodily functions, including metabolism and appetite regulation.
Reducing Appetite
Sometimes, the body confuses thirst with hunger. Sparkling water, like still water, can help keep you hydrated, potentially reducing unnecessary snacking.
One of the primary reasons people incorporate sparkling water into their weight loss journey is its potential to curb hunger. Studies suggest that carbonated drinks can enhance feelings of fullness. For instance, one study revealed that participants who consumed carbonated water reported feeling fuller compared to those who drank still water.
Substituting Sugary Beverages
Sugary beverages like soda and fruit juices are significant contributors to weight gain. Replacing these drinks with sparkling water can substantially reduce calorie and sugar intake, which is essential for weight loss. Many flavored sparkling waters are also calorie-free, providing a refreshing and flavorful alternative without the added guilt.

Aiding Digestion
Another potential advantage of sparkling water is its ability to aid digestion. Research indicates that carbonated water may stimulate gastric motility, facilitating the efficient movement of food through the digestive tract. Some people with a 'slow' stomach, so to speak, find carbonation helps with their gut motility.
Common Myths About Sparkling Water and Weight Loss
Several misconceptions surround sparkling water and its impact on weight loss:
Myth 1: Carbonation Leads to Weight Gain
Some believe that the carbonation in sparkling water can cause weight gain by causing gas and bloating. However, scientific evidence does not support this claim. While some individuals may experience temporary bloating due to carbonation, it does not directly contribute to weight gain.
Myth 2: Sparkling Water is Bad for Teeth
There's a common myth that sparkling water is bad for your teeth. While it’s true that sparkling water is slightly more acidic than still water, the acidity is not enough to erode tooth enamel significantly.
Can Sparkling Water Aid Weight Loss?
Yes, sparkling water can be a helpful addition to a weight loss plan. As discussed earlier, the carbonation in sparkling water may help reduce hunger and keep you feeling fuller for longer. This can lead to reduced calorie intake and, consequently, weight loss. Sparkling water and seltzers such as LaCroix and Topo Chico are often seen as a healthier alternative to soda because they don’t contain sugar or artificial sweeteners.

The Impact on Blood Glucose Levels
A recent Japanese study explored how sparkling water might lower blood glucose levels, potentially aiding weight loss. Akira Takahashi, MD, a researcher and physician at Tesseikai Neurosurgical Hospital in Shijonawate, Japan, designed the study to investigate what happens in the body when people drink sparkling water.
The study compared the process of drinking sparkling water with dialysis, a process in which a machine filters blood to remove waste and excess water when the kidneys no longer can adequately perform this function. His data showed that when carbon dioxide enters the blood and red blood cells, it changes the pH. The slight increase in alkaline in the blood allows the cells to absorb a little more glucose, which lowers blood sugar levels.
However, the glucose reduction is minimal. According to Takahashi, the impact of CO2 in carbonated water is not a standalone solution for weight loss.
Feeling Fullness
Beyond the impact on metabolism and blood pH levels, there are reasons why people looking to lose weight may turn to sparkling water. General weight loss advice recommends increasing intake of fluid, fiber, and protein as a means of amplifying satiety with lower calorie intake.
There’s some research to suggest that the carbonation found in sparkling water increases satiety more than other fluids by increasing stomach distension. Usually people don’t like bloating, but that feeling of fullness can lead them to eat smaller portions or avoid unnecessary snacking.

Potential Drawbacks
While sparkling water has many potential benefits, it’s important to acknowledge that it’s not a magic solution for weight loss.
Some flavored sparkling waters contain artificial sweeteners, which can cause cravings for sweet foods. Additionally, some individuals may be sensitive to carbonation, experiencing gas or bloating after drinking sparkling water.
Expert Opinions
New research shows that drinking sparkling water to help lose weight may not necessarily be a winning strategy. To break down the study's findings, ABC News chief medical correspondent Dr. Tara Narula joined "Good Morning America" on Wednesday and explained that for those looking to carbonated water to support weight loss, the "clinical effect is very, very small -- it might help, but is really probably not clinically relevant."
She said the researchers "compared what happens when you drink a carbonated beverage to what happens to patients with kidney disease who are on dialysis." The data, Narula explained, showed that "when carbon dioxide gets into your bloodstream, your red blood cells, it changes the pH and makes the blood a little more alkaline -- and in that setting, the blood cells are able to absorb more sugar, or glucose, dropping your blood sugar level. National Academies of Sciences, Engineering, and Medicine has determined that about 15.5 cups for men and 11.5 cups for women per day is adequate."
Practical Tips for Incorporating Sparkling Water into Your Diet
Here are some practical tips for incorporating sparkling water into your diet to support weight loss:
- Replace Sugary Drinks: Substitute sodas, juices, and other sugary beverages with sparkling water.
- Drink Between Meals: Next time you’re feeling hungry between meals, try reaching for a glass of sparkling water instead of a high-calorie snack.
- Add Flavor: Add a slice of lemon, lime, or cucumber to your sparkling water for a burst of flavor without added calories.
- Make Your Own: Our Sparkling Water Maker allow you to enjoy fresh, bubbly water right at home, with zero calories and zero sugars. Mineralizing chlorine filter: It eliminates chlorine and adds minerals found in spring water.
The Role of Ghrelin
Not all research supports the idea of carbonated water as helpful for weight loss. Some studies suggest drinking sparkling water raises levels of the hormone ghrelin in the body, which can increase hunger - “although the significance of this is unclear,” Donelan says.
The stomach releases the hormone ghrelin to signal to the brain that it’s empty. Ghrelin levels increase between mealtimes and decrease when the stomach is full. One study that included lab rats and 20 humans concluded that carbonated drinks increased the hormone. People who drank either unsweetened or artificially sweetened carbonated drinks had triple the blood levels of ghrelin compared with those who drank plain or degassed sparkling water.
