Does sparkling mineral water help with weight loss?
Sparkling water is not a weight-loss solution on its own. A 2025 review in BMJ Nutrition, Prevention & Health says carbonated water is "not a standalone solution for weight loss" and that its CO2 effect is too small to expect weight loss. USDA lists plain carbonated water at 0 kcal, so swapping it for a sugary drink cuts calories.

Does sparkling water burn fat or cut weight?
A 2025 review by Akira Takahashi in BMJ Nutrition, Prevention & Health proposes that CO2 from carbonated water may be converted to bicarbonate in red blood cells and may speed glucose use. The author then concludes: “the amount is so small that it is difficult to expect weight loss effects solely from the CO2 in carbonated water.” The review contains no new human weight-loss trial.
Does it make you feel full?
The review says gas from carbonated water can distend the stomach and induce satiety, and cites earlier studies reporting reduced hunger. We did not open those studies, so treat this as a possible short-term effect, not proof of weight loss.
Is mineral water fattening?
No calories are listed for plain carbonated water. USDA FoodData Central lists “Water, carbonated, plain” at 0 kcal per 100 g. Flavored or sweetened versions differ, so check the label. This USDA entry is plain carbonated water, not a specific mineral water brand.
What about minerals and bloating?
The review notes that carbonated water high in sodium has been linked to lower blood glucose in one study, with the mechanism not fully understood. It also says carbonated water may cause bloating and gas, which may matter for people with IBS or reflux. Ask a doctor if you have a medical condition.
