Here’s just some of what happens when you drink a Coke:
Within the first 10 minutes, 10 teaspoons of sugar hit your system. This is 100 percent of your recommended daily intake, and the only reason you don’t vomit as a result of the overwhelming sweetness is because phosphoric acid cuts the flavor.
Within 20 minutes, your blood sugar spikes, and your liver responds to the resulting insulin burst by turning massive amounts of sugar into fat.
Within 40 minutes, caffeine absorption is complete; your pupils dilate, your blood pressure rises, and your livers dumps more sugar into your bloodstream.
After 60 minutes, you’ll start to have a sugar crash.
