So of course, a carrot, which is naturally "low fat" wouldn't count toward what I'm saying here.

Of course, that's well understood. I'm thinking more on things like diet coke. You present it as a fact that it's unhealthy - but do you have any evidence or sources to back up such a claim?

Like you, I tend to believe it's better to avoid such products completely, and if I do drink such products (happens very rarely), I go for the variant with sugar, as I believe the non-sugar variant is even less healthy.

Still, I do not promote this as facts, I promote it as my belief - because I don't think there exist much if any evidence that diet coke is less healthy than water, nor any evidence that diet coke is less healthy than sugary coke.

Of course, doing big research on such topics costs money, such money tend to come from the companies pushing the coke, and their agenda is of course to prove that their products aren't poisonous - there is quite much of a bias there.
