Do fizzy drinks fill you up more than water?

Here's why:

* Volume: While fizzy drinks can have a larger volume due to the carbonation, this volume is mostly air and doesn't contribute to satiety.

* Nutrients: Water is essential for hydration and provides zero calories. Fizzy drinks often contain high amounts of sugar, which can make you feel temporarily full but can lead to cravings and overeating later.

* Fiber: Water and fizzy drinks lack fiber, which is a key component for feeling full.

In conclusion: Fizzy drinks may initially provide a feeling of fullness due to their volume, but this effect is temporary and can even lead to overeating. Water is the best choice for hydration and feeling truly full.
