Are you truly hungry (in that your stomach is growling and hurting) or is your mind hungry?
I did Weigh Down a couple years ago and found that my "settings" for hunger were completely screwed up!!! I went from eating a supersized meal at Burger King with a dessert and still feeling starved to eating half a happy meal and being completely full. Do you know what I mean?
I find it hard to imagine that your stomach could be full of two bowls of soup and still truly be hungry. I wonder if maybe it might be your head? I find that when I eat more than enough food, but it's not stuff that I consider "tasty" or "rewarding", I still feel "hungry", but it's just my head telling me that I deserve to eat something more "fun".
You know what I mean?
I think this is a head issue...part of our old eating habits that we need to vanquish!
That said, if you really are hungry in that your stomach is growling and hurting, you may want to eat a bit of protein...some lean meat, maybe a cheese stick and see if that helps. And I'd add some beans to that soup, Bamie...I think that might help, too. What about Lentils?
Regarding the water, often hunger hides as thirst. When it's really hot outside, I often come in and think that I don't ever want to eat again...I just feel exhausted and thirsty. But as soon as I get enough water in, I'm ravenous! If you haven't eaten in a while and drink your water, then find you are hungry (your belly rumbles and hurts) then you probably are, so eat something! Just make sure it includes protein for lasting fullness and veggies for more fullness and fiber.
