I found this book called Veganist, and it's totally interesting. She talks a lot about the health benefits of eating vegan, as well as the moral issues (which I'm not totally sure I'm buying, but whatever). Anyway, now I know what a vegan eats: Vegetables! Beans! Nuts! Fruit! Whole wheat bread! Brown rice! It actually started making me hungry just reading about all the stuff they eat that I never think to eat. Way better than salad, for sure.
I did a test on myself to see if I could make a vegan meal, based only on what was in my refrigerator at the time. It was easier than I thought. I made a sandwich with whole wheat bread, peanut butter, and raspberry jam, and I made a salad of romaine lettuce, walnuts, and just a smidgen of dressing and cheese (okay, cheese isn't vegan, but I'm not going for the letter of the law here). Anyway, it was good! Way better than I would've thought a vegan meal would be. And it even filled me up faster than my normal food would've. Interesting.
So anyway, I've kept eating that way for a few days now and amazed at how much energy I have. I've always thought I was naturally lethargic, but maybe not. I'm not sure I'm going to go completely strict on this, but I definitely think there could be something to this way of eating.
