What Happens When You Only Drink Coke Or Pepsi?

4. Drinking Soda Instead Of Water Will Trick Your Brain Into Wanting More

Sodas are high in sugar, and that's one of the biggest problems your body will have in consuming it, but not necessarily in the way you might think. These days, we enjoy sugar and sweetened foods pretty much whenever we want, but for hundreds of thousands of years, that wasn't the case.

We evolved in such a way that our brain recognizes the addition of sugar by activating our reward system. Basically, our brain knows on a primal level that energy-rich sugary foods will help us out if we need that energy, so it pings our rewards system by giving us a rush of dopamine. This essentially tells our bodies to keep shoving sugar down our throats.

When we had a low-calory diet thousands of years ago, this was a good thing, but these days, our brains don't realize we don't need that much sugar. When we drink nothing but Coke or Pepsi, you can rest assured that your brain will shoot you up with dopamine, each and every time.

This makes you want more soda after you just finished one, and the vicious cycle that leads to tooth decay, weight gain, and other adverse health effects continues unabated.
