I go between 120-125 lbs usually, so really I only need to drink like 60 ounces of water, but I drink way more than that. I don’t actually measure, but I carry around a 24 ounce Contigo travel cup all the time, and I refill that easily 4 times a day. And that’s not counting more flavorful drinks that I don’t contaminate my water bottle with.
Going by simple math, you should be drinking about 85 ounces of water a day, or 2.5 liters Personally, I think if you need to nickle and dime every ounce of fluid in your food to meet that criteria, then you haven’t created a satisfactory water drinking habit, yet
We don’t usually have to talk about salt in drinks, but while salt is an important nutrient, it would also fall into the CRAP category I mentioned earlier, because it’s dehydrating just like caffeine, refined sugars, alcohol, and processed chemical ingredients that need flushed from your body with… Water. So no, you can’t just count a bowl of campbell’s soup as water. If we’re talking condensed soup, where you know exactly how much water you add to it, I suppose you could count some, but not all of the water added. You have to account for the negative affect of the salt in the soup. However, not all soup is created equal. If we’re talking homemade soup made from homemade stock that has nothing other than water, bones, and the juices extracted from the vegetables in it… Then heck yeah, I’d let that pass for your water content. That’s liquid gold.
Milk I would also consider acceptable, but really shouldn’t be counted at full liquid value because of the fat, protein, and sugar suspended in the water.
