1 mmol/L of the ketone body betahydroxybutyrate, measured in serum), a higher 4:1 ratio ketogenic diet can produce higher ketone body betahydroxybutyrate levels and more rapidly (up to 2 mmol/L within 24 hours of initiation). Have a good breakfast so that your body is energized for the day which also maintains the blood sugar levels. Serve with whole grain toast and sliced fruit for a complete weekend breakfast. So this shows a whole balancing mechanism, it allows a shift from purely glucose to glucose and BHB. Cool. So that coincides nicely with an increase in ketones and takes care of the BHB uptake, balancing out low glucose with increased BHB. Also here the astrocytes may start to produce lactate but it won’t do any good because under hyperglycemia, there won’t be any BHB produced. Astrocytes can store small amounts of glycogen which they, if necessary, break down to glucose and metabolize to lactate (Falkowska et al. There may be a point that can be crossed when too much glucose is available and can be considered toxic when that downregulates GLUT1 in the BBB to the point that the brain doesn’t get enough glucose.
