Blood Sugar Levels During an Extended Fast – Sep 2017

Here are some observations based on data of my Blood Sugar levels during a 25-day Extended Fast.

  • Blood Sugars go up significantly during the first few days of a fast. [2017-12-06: See (Fasting induces a form of autonomic synaptic plasticity that prevents hypoglycemia)].

    Although there are redundant control mechanisms that maintain glucose homeostasis, a rise in circulating epinephrine is a key event in the response to food deprivation. This effect involves epinephrine release from the adrenal medulla, which increases hepatic glucose production, inhibits insulin release from pancreatic β-cells, and stimulates glucagon release from pancreatic α-cells. Taken together, these findings support the idea that the NPY-dependent rise in circulating epinephrine contributes to the increase in glucose production that is needed to maintain euglycemia during food deprivation.

  • The Blood Sugar “high” level is still nowhere near a dangerous level.
  • Blood Sugar peaks at 3-4 days into the fast and then drops rapidly.

  • Blood Sugars drop into the range considered low by the meter and stay that way through the rest of the fast.

  • The two high values are related to HIIT (High Intensity Interval Training Exercise). See my Cori Cycle BLOG post for more details.
  • After the fast my blood sugars are better than they were before the fast but I have added an exercise component to my routine.
