Does drinking water help with fat loss?

I've recently seen the merits of drinking large amounts of water and it's effects on fat loss being mentioned in a lot of places. In one day I saw it mentioned in Craig Ballantyne's blog, Lyle McDonald's bodyrecomposition.com forum and in two newspaper articles.
Time for me to add my 2c.
Overall - the research seems mixed. Whether drinking extra water has an effect or not remains to be truly proven. The original research showed that drinking two liters of water raised metabolism about 100 calories. That would definitely add up. The latest research says the old research was wrong and that although cold water does raise metabolism -- it's a very small effect.
So last year cutting edge trainers recommended additional water for fat loss. Now they don't.
I guess the research next year might show the opposite and water will help again. Until the next research project shows differently and that water doesn't really help- etc etc etc.
As much as you should always study research, you have to learn to apply it in the real world.
So regardless of the research - I work in the real world with real clients. Scientists and internet forumites can debate amongst each other. I'm interested in real world fat loss, what works and what doesn't - so here's my take.
Dehydration inhibits fat loss. This I'm convinced of. In fact dehydration will eventually kill you , and fat loss slows down a lot at that point!
So before we worry about extra water intake - we need to worry about minimal and optimal fluid intakes.
Let's look at a typical beginner clients fluid intake per day before they come to see me (and EVERYONE tells me they drink A LOT of water by the way).
Wake up: A cup of coffee
Mid morning: coffee,
Lunch: Diet soda
Afternoon: Coffee or diet soda
Dinner: diet soda, occasionally wine or a beer.
So you could make the case that the average beginner is not adequately hydrated anyway - never mind hydrated for training/fat loss/dieting etc.
I have rarely seen a client come in drinking more than about 16-20oz a day in the beginning stages.
So here's what we did at our gym: we bought half gallon jugs and slapped our logo on it.
Every new client gets one - and we tell them : fill it up first thing in the morning - make sure it's finished when you go to bed. Most clients don't have a problem with that -- and some start drinking more water on top of that.
This seems to do two things - adds much needed pure water to their systems, and eliminates the crap they were already drinking.
So does it have an effect on fat loss? I think in the early stages - it does. But the effect is more becasue we're going from dehydration to optimal hydration than anything else. I don't think the "super-hydration" stuff that is being preached really amounts to anything.
But as usual – in the real world most of us just aren’t drinking enough pure water – I think there can be a ton of benefits to increasing water intake in general. Is an extra glass or two of clean water be likely to hurt you much?
