I also have realised teh difference in my body.Earlier I used to eat anything 'rich', i used to feel heavy, very heavy.You can imagine how heavy had I felt after 'stuffing myself with so called 'rich ' food.But i never used to feel this heaviness in body during this stuffing period past the uncomfortable point. But now I am noticing thsi change in myself.Whenever I try to eat 'rich ' food , I have started recognising this feeling of heaviness even before it starts. I sense it very well that now even if I eat one more morsel of food , I will feel heavy .So now Most of the times I am able to stop muself before any such point.

So now I think., that one's eating habits also depend on how much good tuning one has with one's body.
