Many health insurance plans have an out-of- pocket expense maximum. An out-of-pocket expense is a nonreimbursable expense paid by a patient. But out-of-pocket expenses can also include covered expenses that you are responsible for before your health-plan benefits kick in at 100 percent coverage.
The process of ketosis is one of the physiological effects of fasting in which the brain (and some other bodily processes) uses ketones produced from fatty tissues as a fuel instead of the usual glucose. This is called muscle sparing.
With no insulin (which is a fat storage hormone) present, your body burns stored fat as its primary fuel. When that happens, your body releases ketones into your bloodstream, and you are in ketosis. This state may cause a host of temporary symptoms. It will also show up in your urine as ketones.
