Well, according to Weight Watchers, you can count it.

I put cream in mine so I don't count it. I have no idea if that's rational.

Many diets allow coffee, but because it's a diuretic (makes you pee) it's usually not counted as a water source. Same thing with diet sodas.

Weak tea is more accepted as water substitute. And then there are the purists who won't imbibe anything but plain water.

When dieting, I don't count coffee as a 'water', but I do know that you can lots of drink coffee and drink very little other liquids and survive for years. I know this because I've lived it. I don't recommend it, though. ;)

i dont know about what the diets follow. but i dont count coffee as water. In yoga preachings, we were taught that water is a NATURAL MEDICINE and we cant count it as coffee or tea.

just my opinion.

It is allowed in most diets I am pretty sure, but I think unless it's plain - no cream/milk/sugars you don't count it as water.

So what I do is when journaling my daily foods and counting the calories (well, I let myfitnesspal.com count them for me lol) I will count my fat free half and half that I put into the coffee but not the coffee itself; and then I won't count the coffee into my water intake.

No I don't count it because its like alcohol and dehydrates you my Dr told me when I went in to urgent care years ago for borderline dehydration. Have one cup and drink water the rest of the day.

Decaf could count as water the same with herbal tea, but to a point. You wouldn't want to try and get all of your water intake from substitute sources.
