The term U.S. Real Property interest means an interest in real property (including an interest in a mine, well, or other natural deposit) located in the United States or the U.S. Virgin Islands, as well as certain personal property that is associated with the use of real property (such as farming machinery).
Ketosis is an eating plan where the body uses ketones to fuel the brain and body instead of glucose like most people use when on the SAD (standard American diet). It can be very helpful for blood sugar and consistent energy because fat is a very stable source of fuel.
Of course, I believe that the paleo template is good starting place for optimal health but ketosis can be an add-on or tweak for people who get stuck or feel hopeless. It can be a powerful and effective way to lose weight without hunger and many of my friends have had success with it.
