To be honest, I'm not too educated on food science. I know that I began counting calories; once I started taking in less calories than I was burning, I started losing weight. I dropped over one hundred pounds in a relatively short amount of time. At the time, I don't really focus on sodium or other things that people get hung up on... maybe I'll pay for that later - I don't know. I just know that, regardless of fat, when I started counting calories, I lost weight.
If you're frightened of dying, and you're holding on, you'll see devils tearing your life away. But if you've made your peace, then the devils are really angels, freeing you from the Earth.
