I had a conversation today with a client, who said that since she's changed her diet to one that is lower in fat and higher in fiber, she experiences a "different kind of fullness". I asked her to explain.
She said that when she ate a "meat heavy" diet, she felt full a lot of the time, and really liked that feeling. With much less meat, and other fatty foods, she gets full, but it has a different quality.
How interesting! Wouldn't you think that full is full?
I think that when we aren't eating what we REALLY want, we can be physically full, but not SATISFIED. There's a difference between full, and SATISFIED. For me, satisfied has several dimensions, physical, mental and spiritual or psychological. If you "fill up" just one of these, say the physical, the others just might not be satisfied. This might explain my client's observation that the fullness she feels on a lower fat diet isn't the same. This might be OK with her, or it might not.
