Glucose capacity of blood

I’m not certain where this belongs…

I’m trying to calculate the calories of glucose residing inblood. I fast and do 400 or so calories of cardio most mornings…

Let’s say my blood glucose is 200mg/dL. That would convert to 2gr/liter. The typical human body has 6liters? So that would be 12gr in the blood stream. Glucose has 4cal/gram. So even a diabetic level of BS contains only 48 calories residing in the blood stream?

indeed - my understanding is roughly 1tsp = 100 BG reading. 5 tsp and you are ready for the ER.
Thats why insulin (1/2 life of 3 minutes) has to come to the rescue right away as glucose is released into the blood by the digestive process… and why having the readily absorbed refined/processed carbs are so horrible.
Most of the glucose energy resides in glycogen stores all over

Thanks. I was trying to validate calcs. It seem so low! If someone has a healthy blood glucose level then there’s no significant calories in their blood! So any moderate to high cardio work out 600-800cal/hr is all pulled from stores either local glucose or gluconeogenesis…
