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.
Early ketosis symptoms usually last for several days or up to a week in some people. This typically continues until the body is used to burning fat instead of glucose. After the several days, the levels of ketones in the body will lessen, but that does not mean you are no longer losing weight.
