First, let’s state the obvious: carbonation is a gas delivery system. Every single can of Diet Coke is pumped with carbon dioxide, which creates those fizzy bubbles. When you drink it, you’re literally swallowing a bunch of CO₂—and that gas has to go somewhere.
Your body isn’t a magician. It can’t just wave a wand and make those bubbles disappear. Instead, they travel through your digestive tract, and if you drink too fast (or too much), you’ll end up with a belly full of trapped air. That’s burp territory, friends.
But here’s the kicker: Diet Coke isn’t just fizzy water. It’s also packed with artificial sweeteners—specifically aspartame and acesulfame potassium. These are the real troublemakers when it comes to the low-end gas (if you know what I mean).
