Fran Susín, an expert in diet, on sparkling water: “There are studies that show that it helps a lot with digestion”
The nutritionist shares a new video on his TikTok profile where he focuses on the benefits and common myths of drinking fizzy water.
For years, sparkling water has lived under a cloud of myths and mixed opinions. Most commonly, people claim it “bloats you,” “makes you hungrier,” or “isn’t good for your diet.” But the science is straightforward: sparkling water does not make you gain weight. It contains no calories, no sugar, and can absolutely fit into a healthy lifestyle.
The main reason is almost laughably simple: sparkling water is still just water. The only difference is the added carbon dioxide that creates those bubbles.
It has no calories, no fat, and no carbs — meaning it can’t cause weight gain. The confusion usually comes from lumping it together with sodas and sweetened carbonated drinks, which do contain sugar, syrups, or artificial sweeteners. But not all fizzy drinks are created equal.
Bloating isn’t the same as gaining weight
One of the most common complaints about sparkling water is that it “makes you feel bloated.” And yes, that can happen — but only temporarily. The carbonation can cause mild abdominal distension, a short‑lived sensation that has nothing to do with gaining fat or actual body weight.
@fransusin_ 💧 ¿Agua con gas… sí o no? Pues depende de ti 😉 A mí, por ejemplo, el agua con gas me va bastante mal: barriga hinchada, gases, distensión… Pero ojo: también hay estudios que dicen que puede mejorar la digestión e incluso bajar el colesterol. ❗Importante: el agua con gas no engorda, así que no la descartes por eso. Lo que puede pasar es que te inflame un poco si ya tienes el estómago sensible. ✅ Mi conclusión: si la aguantas bien, adelante. 👇 ¿Tú cómo te llevas con el agua con gas? #FranSusín #Salud #Nutrición #ConsejosSaludables #EtiquetasNutricionales #AlimentaciónSaludable #Mercadona #Hacendado #Carrefour #Lidl #Aldi

Nutrition expert and content creator Fran Susín offers a candid take based on his own experience. “For me, sparkling water causes gas and bloating,” he says. Still, he emphasizes that this varies widely from person to person and isn’t a reason to demonize it.
Science-backed benefits
Beyond debunking myths, sparkling water comes with real advantages:
- It hydrates just as well as still water, helping you meet your daily fluid needs.
- It may support digestion for some people by stimulating gastric activity.
- It can increase feelings of fullness, which may help reduce overeating.
- It’s a healthy alternative to soda, making it easier to cut back on added sugars and empty calories.
When sparkling water might not be the best choice
While it’s safe for most people, it’s not ideal for everyone. Individuals with acid reflux, frequent gas, or irritable bowel syndrome may experience more discomfort — just as Fran Susín does. It’s also worth checking the label, since some sparkling waters contain added sodium, which matters if you’re watching your salt intake.
