Glucose is only necessary for a minority of cells.
High glucose indicates that my dietary intake is basically above my body’s needs.
This usually goes hand in hand with insulin and the longevity research points to low glucose and low insulin as being keys to longevity and health.
This is because glucose oxidation is more destructive than fat oxidation (more free radicals) in mitochondria so it promotes faster aging and potential DNA damage.
Also, if I want to remain ketogenic, the liver uses glucose as a trigger and will no create ketones if glucose (and so insulin) is elevated.
This means that I would be storing fat instead of burning fat when glucose goes up.
I also feel better on high ketone, low glucose.
