Based on research by health writer Wade Meredith, it explains that a 330ml can of Coca Cola contains so much sugar, your body should vomit - but the phosphoric acid "cuts the flavor", helping you keep the liquid down.
After 40 minutes, your blood sugar has spiked, your pupils dilated, and your blood pressure has risen.
The body starts to produce more dopamine, a neurotransmitter that controls the brain's pleasure centres - "physically the same way heroin works, by the way".
By the time the hour is up, you will want to urinate, and start to have a sugar crash, making you drowsy and irritable.
"You’ve also now, literally, p***** away all the water that was in the Coke. But not before infusing it with valuable nutrients your body could have used for things like hydrating your system, or building strong bones and teeth," the account concludes.
