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.
In practical terms, consuming protein at or above .8 grams per pound is enough to kick you out of ketosis. Ideally, an optimum ketogenic state would require you to be at about 75% fat, 5% carbohydrates, and 20% protein, which would allow you to perhaps maintain lean muscle mass.
