It has occurred to me recently that I have been eating less, and I am really excited by this. I have tried to do this intentionally before in the name of eating only my fair share or being healthy, but the thing that has really whipped me into shape has been cooking for myself and buying in bulk.
I didn't cook for myself at school, and the cafeteria was "all you can eat." I took whatever I wanted. I tried not to waste food, but it still happened sometimes when I didn't like a dish.
Now that I cook for myself, I know that I have to eat what I cook because there just isn't another option for lunch or dinner, etc. I know that I can't eat as much as I want, because the food comes at a price and it comes from somewhere.
For example, take bread. Now that I make my own bread, every piece has the feeling of time and effort attached to it, and I am much less likely to OD on it.
My lunch today consisted of: one slice of bread, a half cup of cooked lentils, a couple tablespoons of tuna salad, one 1/4" slice of cheese, a carrot and an apple. That's like...epically healthy in my world.
