What are the differences between Diet Coke Diet Coke caffeine free and coke zero?

The answer to that is ah-bious! Diet coke caffiene free is diet coke with out caffiene. Coke zero has no calories or sugars. Diet coke is for fat people on a diet or people that wanna stay in shape.

That's actually somewhat not true because yes, it does help people on a diet that like coke but coke 0 has no calories so I think it is scientificly proven that coke 0 is't not as fattening.
