IMO, i would drink diet sodas to replace water.. you still need to drink lots of water.. but i would drink a diet soda instead of a normal soda.. also look for diet sodas made with splenda as the sweatener and not aspratame (sp)
some are diet big red and Diet rite cola.. both of which taste pretty good for a diet drink.
From a guy part of the "Diet Coke Generation", no. Literally, when it was introduced in the mid-80s I've been drinking it. If I didn't have the metabolism (even at 40 thank goodness) I have, I'd be a "skinny fat person".
I only drink like 1 a day when I'm at work. Usually about 12 oz. Fuckin fat pigs around here (at work) eat all this tasty food that I cant eat becuase I'm trying to lose weight so I'll have a diet coke and a healthy snack to curb my appetite.
