Food Choices

I know I've spoken a lot about eating what ever you want when hungry but not much emphasis  has to be on how food makes you feel after eating.  If I feel sluggish after eating a certain food, next time I may only eat a smaller portion and add some fruit and vegetables to that meal. I also pay attention to my joints and other parts of my body like my stomach and how often food passes through my body.  How many times should one pooh in a day?  I notice when I eat more leafy vegetable the scale drops  and that should be a clue for the next time I get hungry.
