The fizz and texture in carbonated drinks trick your brain into thinking you're eating something, even if there are no calories.
Scientific Claim
Oral sensory stimulation via carbonation enhances dopaminergic signaling in the brain, increasing perceived satiety independent of caloric intake.
Original Statement
“We have oral sensory nerves in our mouth. Okay? So oral sensory nerves are things that perceive different sensations in our mouth. And we've seen it with sodas where a sweet flat beverage compared to a sweet carbonated beverage. The sweet carbonated beverage actually gets more of a dopamineergic hit.”
