I don't post zero-cal stuff I drink. Should I?

I track it because I added sodium to my tracking. I didn't add it for blood pressure but more for water retention in making sense of weigh ins that seem conflicting. Note, I weigh myslef at least once a day, lol.

Zero cal beverages often have a whole rack of other things in them (like sodium) that could be beneficial for you to track. There can often be carbs coming in the form of drinks you would not expect them to be in!

I think it's a good idea to log anyway because sometimes things like caffeine can hinder weight loss. I heard of a woman who gained a few kilos even though she had continued eating well. Turned out she was stressed at work and starting drinking more coffee than usual. Once she stopped that the weight fell of her. So it's not just about logging calories.

You know I just read about this today and started scratching my head on my own caffeine intake. It's different between individuals but never thought of it to hinder.

If sodium is a concern to you then yes, otherwise dont worry about it.

I would only track it if it contains something in it that you believe you need to track. In my case the answer to that would be "no".

I think it depends on whether or not you need to track what's in it, for instance, if you are watching your sodium intake. And also whether you drink a LOT of it. If you don't have concern about sodium, and you don't drink a ton of whatever it is, I would not worry about it. I don't drink diet drinks as a rule, but I will have a Diet Dr. Pepper every once in a while. I don't log it, because on most days my sodium intake is well below my allowance.
