I'm not any kind of physician or anything, but this is what I understand. As the body burns fat, it gives off keytones, when you reach a certain level of burn it's called ketosis. You can actually test for this condition with a strip of litmus paper dipped in urine. Anyway, if your body contains a high level of keytones, they can be reabsorbed into your body helping you to store fat when you do eat. Sort of a way for the body to prime itself for optimal fat storage when does get food. If you drink a lot of water the keytones get flushed out, making your body less able to store fat from the next meal. That is one reason, another reason is that when you are dehydrated the ratio of water to salt in your body gets a little lopsided and you will actually retain water in your cells (or between them?) and show a water gain on the scale. I think it has something to do with the chemistry of salt, whatever free electron it has attracting this or that etc etc. (I took chemistry eons ago, and I didn't remember it well even then). Also when people are trying to create a calorie deficit they tend to workout and bring on a sweat, so you have to replenish that as well.
For weight loss you should be drinking 64 oz baseline + another 8 oz for every 10 lbs you want to lose. So by my estimate you need to be drinking 120 oz. Sorry, more trips to the potty for you LOL. Actually I try and break my water drinking up throughout the day, drinking it all at once is really hard. I have a 24 oz bottle during my morning workout, another between breakfast and lunch, one between lunch and dinner and another for dinner. At meals I'm either finishing the one that I had between meals or I'm starting the next. Typically I drink 96-144 oz of water per day.
