I know fizzy drink on the whole isn't good for your teeth or your body in general. Unfortunately, I drink alot of Pepsi Max. On average I drink about 2 litres a day. This I know can't be good for me or anyone for that matter but I am not worried about whether or not it is good for me. What I want to know is whether or not it is fattening (such as a block of chocolate is). On the bottle is says it contains 'no' fat, 'no' sugar, infact.. it doesn't seem to contain anything at all but a small amount of sodium (from memory) which brings me to the conclusion it isn't fattening - it is basically just water with some flavouring. That said, does that mean someone could drink as much Pepsi Max as they want and never put on weight because of it?
