Carbonated waters and weight loss: Don’t expect too much | CNN
Fizzy, sparkling, carbonated, or seltzer—whatever you call it, bubbly water has long been a favorite for its refreshing taste. On Tuesday, January 21, 2025, experts shared new insights into its potential impact on weight loss, shedding light on both benefits and misconceptions.
Social media has been buzzing with debates about whether carbonated water can help or hinder weight management. Some argue that it might increase weight by stimulating appetite, as suggested by a small February 2017 study. This study indicated that carbonated drinks raised ghrelin, the hunger hormone, but the results came from male rats and only 20 human participants, making the findings far from conclusive.
However, many believe that sparkling water might actually promote weight loss. One reason is that its fizzy bubbles can create a feeling of fullness, making people less likely to overeat. Additionally, water, carbonated or not, plays a vital role in metabolism. It supports lipolysis, the process by which the body converts stored fat into energy.
A recent study has introduced a fascinating new perspective. Researchers have discovered that carbonated water might lower blood glucose levels, an essential factor in managing weight. Stable blood sugar helps the body burn fat more effectively between meals.
“When carbonated water is consumed, CO2 is absorbed into the blood vessels in the stomach,” explained Dr. Akira Takahashi, a physician at the Tesseikai Neurosurgical Hospital in Japan. He emphasized that this process could influence glucose levels in ways that benefit weight management.
The study explored how carbon dioxide in water interacts with the body. Natural carbonated water, found in volcanic springs, is infused with minerals and bubbles. Most commercial sparkling water, however, is made by adding CO2 under pressure. Despite the difference in origin, both types seem to share similar effects on the body.
It’s important to note that not all carbonated beverages are created equal. Soda and sweetened sparkling waters contain added sugars and calories, which can lead to weight gain. Plain carbonated water, with no additives, is a healthier choice. It provides hydration, aids digestion, and, as research suggests, may help with appetite control.
Experts stress moderation and awareness. Drinking carbonated water alongside a balanced diet can be a useful strategy, but relying solely on it for weight loss is not advised. Healthy eating and regular exercise remain the cornerstones of any effective weight management plan.
The new findings add to the growing list of reasons why sparkling water has become a favorite among health-conscious individuals. It offers a calorie-free alternative to sugary drinks, keeps you hydrated, and may even support your weight loss journey.
As more studies explore the benefits of carbonated water, one thing remains clear—it’s a refreshing way to stay healthy. Whether you enjoy it plain or with a twist of lemon, fizzy water might just be the perfect companion on your path to better health.
