Default Sources of Blood Glucose

Quick question,

I'm aware of a couple sources of blood glucose. First, is the obvious one - eating carbs. Then there is the liver "dumping" sugar into the bloodstream - Gluconeogenesis. Apparently, the kidneys get in on the glucose dumping game as well.

Source: Gluconeogenesis - Wikipedia, the free encyclopedia

And I've read there are short term sources of energy. I think I remember from my Atkins days, years ago, that in the first few days of induction things like triglycerides are burned off quickly.

I'm wondering if there are any other sources of BG in our bodies?

Any place that can store glycogen for fuel is a source. So the liver, as you mentioned, and muscles, quick fuel for them.

The fundamental sources remain carbs and, in the case of gluconeogenesis, glucose produced from non-carbs like protein - the foods we put in our mouths. That glycogen may be shuttled off to the liver for later dispensing, as in liver dumps, but whatever we eat is eventually going to show up in our bloodstream as glucose. This is why the ketogenic plans work better because by sharply reducing carbs and maintaining a proper ratio of protein & fats, we can somewhat deplete the stores of glycogen so that the liver has fewer reserves to convert to glucose and the 'dumps' aren't so big.

As Shanny's said all we eat can be turn into glucose it just that all carbs are turn into glucose then if you have excess protein the body can turn that into glucose and even a tiny bid of fat can be turn into glucose if in a starving situation. The problem with diabetes is that the body has a hemostatic system to control blood glucose. Glucagon that is also produced in the pancreas stimulate the gluconeogenesis and among others hormones causes the increase in glucose. Insulin is supposed to not only reduce glucose in blood but to suppress glucagon. The problem is the hemostatic systems doesn't work well as it should. So the first substrate to reduce is carbs which is basically glucose, your body doesn't need any, it already has more that it should. Proteins are needed for tissue repair and other vitals functions so you need to provide only for what you need, that will depend on age and exercise levels, but in excess will turn to glucose just not as quickly and efficient as with carbs. Fats has to be your main fuel since is your best source.

I'm slowly internalizing that "fat is good". Think it will take a bit more time.

Was asking because I'm seeing patterns in BG levels relative to how I eat, as opposed to what I eat. Was wondering if what I was seeing was my liver at work. As usual with this condition, things appear to be more complicated than anticipated.

Yep,

We've got a complicated system and the numbers we see on the various foods are only a starting point.

We are all different and over the month we change, particularly the ladies amongst us. And that ignores the complications that things like infections, stress and tiredness throw into the mix.

Our meter is the tool that tells us whether this food or that works for us, the way we serve it in the amount we eat. On these occasions me, me and ME are the only ones we should consider.
