I'm working in an office where Coke, Coke Zero, and Sprite are stocked in the fridge and free to take. And it's very hot outside!
So for a while there I merrily drank a Coke Zero a day. Even though I know it's bad for me, it's just so refreshing. And there's no calories!

Coke and other sugary fizzies
We know sugar is bad for us. We also know that Coke is loaded with caffeine and calories. So it's really a no-go area.
In addition, fizzy drinks have been linked to lower bone density, since they can block your bones' absorption of calcium. Coke is also extremely acidic. The acid residue can be extremely hard on the kidneys since they have to filter it.
Diet Coke and other sugar-free options
Diet options don't have calories or sugar, but they have the same effect on your bones and kidneys. And, ironically, diet options have also been linked to weight gain.
Diet options also contain aspartame, which is an extremely controversial sweetener. I have definitely experienced bad skin and headaches from drinking Coke Zero and Diet 7up in the past.
Keeping Beautiful's verdict
There is a lot of controversy over just how bad sugary and diet fizzy drinks are for you and many of the claims may be exaggerated. However, considering it's your body, do you really want to risk it?
Aside from anything else fizzy drinks are really addictive, and if you don't break the habit now it could become a lifetime one. If you treat yourself once in a while its fine, but remember treats are for occasional consumption only!
