Here’s what happens after you drink a Coke:
In the first 10 minutes: Ten teaspoons of sugar (100 percent of your recommended daily intake) hits your system.
In 20 minutes: Your blood sugar spikes and causes a burst of insulin. Your liver responds by turning the sugar it comes into contact with into fat.
In 40 minutes: Your body has absorbed the soda’s caffeine. Your pupils may dilate, your blood pressure rises, and your liver “dumps more sugar into your bloodstream.” The adenosine receptors in your brain are blocked to prevent you from feeling drowsy.
