Why/how Does Fat Increase Blood Glucose?

Freema said:
yes thats also the reason why I have started lowering my proteins and hightening my fats but I seem to have a hard time loosing weight since that change even on a 1000 calorie diet and very hard training weekly like at least 12 hours a week....

Hi @Freema - I don't want to derail this thread but your comment here made me wonder if you weren't possibly overtraining & undereating thereby slowing your weight loss progress. I might be worth backing off on the exercise (particularly any hard cardio) & eating maintenance calories for a week or so to see if that doesn't kick start things for you. Just a thought
 
Maybe the High sudden Waves like flooding of insulin do change more fats than the expected "normal"10% conversion into glucose than when insulin comes from the pancreas in a more natural flow and that higher wave induces the accellerated conversion of fats and ends up in the second wave of spiking of glucose originating from the fats some hours later

Yes you may be right I am thinking of that too But I love training hard and dont want to get out of my good period of it , I am the kind that can fall down into passivity when depressed and it is in the back of my head always , so I am thinking more of eating some more for a couple of days to calm my body away from fearing servere hunger

As I said before, the process of gluconeogenesis creates glucose in the blood from protein or fat. It needs insulin to be low as well as low bgl levels, it it is self regulating. As glucose is created, so insulin goes up (in a T2 that is) and this turns off the gluconeogenesis path. So the body just makes what it needs to survive,
The blood bgl comes firstly from carbs metabolism which is the most efficient means. If there are low carbs then the body uses protein instead, but this is only about 10% efficient compared to carbs. If there is low protein as well, then eventually the body turns fat into glucose. But this is an emergency situation needed to maintain glucose for vital services such as the brain lungs and heart. It is very inefficient and will not flood the blood with glucose, just merely top up the low levels to a slightly higher level, It will not give much in the way of spike on a meter. You are, I fear, giving too much prominence to fat as a source of blood sugae (in a T2).

The case for T1D seems different. Excess fat seems to interfere with the insulin that was injected as a bolus and stops it from acting on bgl for a while possibly by making the liver storage path resistant so that bgl is not stored for a while and bgl remains high from the carbs or protein. We only have the experimental results but no explanation yet for T1

EDIT to Add: Tonight we had pumpkin soup with bread and butter (moi aussi) and it had 2 quarts of double Scream in it [Halloween touch there].. so an HF meal for me, with second helping. Bulletproof coffee to follow, and half a pack of salted cashew nuts. My pre prandial was 4.2 mmol/l, my 2hr PP was 5.4, and my 4hr PP was 4.6 So no spike so far.

Okay Yes and insulins seems to be low very often but not low enough and not for long enough in type 1 because of the frequent injektions so glucoegenesis would NOT happen in waves in between insulin injektions

So you say It is two different roads or triggers that creates glucose from carbs on the one hand and on the other proteins and Then fats in the third Road ?

Yes, I believe that is true.
 

I hear ya @Freema - cardio is my happy place too but I just have to remind myself that excess cortisol from too much cardio can increase insulin resistance which defeats at least one of the purposes of the exercise I actually use cardio (mainly HIIT cycling or mountain biking) to help me keep my weight up as for me it increases my appetite (I'm aware it doesn't work that way for everyone) but in the hopes of staving off a full type 2 diagnosis I tend to stick to relatively low impact (& low cortisol!) stuff like yoga, hiking, kayaking & resistance training. Either way - anything you can do to keep your mind/body from getting stressed has got to be good for you right?
 
A regulator. That is why very few hypos on hf too.
