I am in hour 104 of an extended fast( coffee and water). Yesterday my BG went to a 41mg/dl which had me concerned but I felt fine so I didn’t eat and a BHB of 6.8mmol/L. Today 3 hours after waking I was 56 & 5.5. My assumption is that my free BHB wasn’t as free, it needed to be used and conversely I needed more energy so either gluconeogenesis or fat oxidation of triglycerides created the glucose.
My question based on this then are: If I could test blood fats would I see a higher level of triglycerides? I suspect these are what is being broken down for the amino backbone and the fat oxidation.
Thanks for any input, corrections or discussion.
