My BP is always at a nice number when I have fasted. Why is that?
When you are young, your internal organs have excess capacity and can handle anything you throw at them and still cleanse and maintain the rest of your body. As you age their capacity diminishes until they can’t handle everything you throw at them anymore. When there is food in your stomach, 50% of the capacity of your internal organs is going to simply digesting food. When you have an empty stomach, that freed-up 50% capacity can be directed toward cleansing and maintenance of your body.
