Ok, so it seems that I am eternally on a quest to figure out why I'm hungry all the time. I've thought so many times that I've found a cure/miracle food/eating method or routine for it, but the hunger has come back again stronger than ever!
The last few days, I've been drinking less water as an experiment, and voila.... Hunger is way less, I'm eating smaller meals and not ravenous at 10am after an 8am breakfast!
I'm still drinking 8 or more glasses of water (about 2 litres), whereas before I was drinking 3 or 4 litres of water per day.
So, does drinking water in excess make you hungrier, and if so, what's the science behind it? Does it dilute stomach acids/juices? Has anybody else had this experience?! Or is it even possible since water is supposed to fill us up and suppress our appetites?
If you drink excessively you can gradually become hyponatremic, i.e. the sodium level in your blood falls (the reason why massive amounts of water drunk quickly would be fatal). Increased intake of sodium would help to counteract that, so in theory a desire for the salt in food could be connected. Whether that's the case in you of course I have no idea!
Was 4L a day because of thirst? Needing that much would be unusual for most people, there are some causes of excessive thirst worth excluding if that was the case. (4L for a petite inactive person would obviously be different to 4L for a huge, sweating sportsman but your post didn't indicate your needs).
It may of course be unrelated and you've just finally got used to what you're asking your body to do with your diet!
I don't have a scientific answer, but I've experienced the same phenomenon. I'm eating around 3500-4000 calories per day, I consume around 3-5 liters per day including during 1.5 hours rowing.
The hunger never bothers me, but I do notice a gnawing in my stomach sometimes between meals.
