To be precise, some of the fuel does need to be glucose. There is no such phenomenon as solely relying on ketones for energy, and the brain is especially glucose greedy.
In a sufficiently fasted state, all of that glucose will be endogenously produced rather than coming directly from food, but it does need to be there.
- techbio 5y agoEndogenously, from the fat/glucose pathway. Not sure that any glucose is required to be consumed directly. But we do love sweets, and fat cells love saving energy.
