No, plain carbonated water does not cause weight gain.
Why it does NOT cause weight gain:
- It contains zero calories
- No sugar or fat (if unflavored)
- Works similarly to regular water in hydration
When weight gain can happen:
- If the carbonated drink is:
- Flavored or sweetened (soda, soft drinks)
- Contains added sugar or artificial sweeteners
These can increase calorie intake and lead to weight gain.
Additional insight:
- Carbonated water may even:
- Help with feeling full (satiety)
- Reduce overeating in some cases
Key Takeaway:
Plain carbonated water does not cause weight gain, but sugary carbonated drinks can.
