Hi All, 

I would argue that elevated fasting blood glucose in the context of a low
carb diet is suggestive of excessive protein intake and inadequate fat
intake. When we need energy, our livers will utilize proteins to produce
glucose for energy, by a process of gluconeogenesis. The liver will make use
of dietary proteins or, when these are not available, self-proteins, usually
beginning with breaking down and using muscle proteins for glucose.
