Instead, your body normally uses glucose, which it creates from carbs, to fuel your cells. You have enough energy as a result to perform your obligations. However, when you deprive your body of glucose, your organs have to work extra hard to fuel your cells. This goal is assisted by the ketone bodies that are created during the process.
When you're in a ketotic state, your body burns fat for energy rather than glucose. Your body will continue to use fat as fuel if you constantly deprive it of glucose by restricting your intake of carbohydrates. First off, studies have shown that the deeper you go into ketosis, the longer you stay in it.
