These are the exact two points I was going to mention. The phosphoric acid in cola-type sodas (both regular and diet, so any coke or pepsi or generic brand cola) steals calcium from your bones. With osteoporosis rates as high as they are (especially for women), I try to avoid these most of the time now.

Caffeine is a natural diuretic, so whatever water is in the beverage is basically negated by the caffeine. Also, I believe diabetics (type 2, anyway) are more prone to high blood pressure, and caffeine isn't good for the blood pressure and can cause an increase in blood glucose levels for some people.

All that said, I still drink diet soda every day I opt for diet ginger ale and diet orange soda, both of which are phosphoric acid and caffeine free.
