The carbon dioxide in seltzer may slightly boost metabolism — but these zero-calorie drinks can also help you feel fuller and cut down snacking.

The body absorbs the carbon in a way that “may support weight loss,” according to a new study, but carbonated drinks are not a “standalone solution”

Don't expect to shed pounds solely due to your choice of beverage. The benefits of drinking carbonated water for weight loss are “so small that it is difficult to expect weight loss effects solely from the CO2 in carbonated water,” the study notes.
