Protien v carbs and glucose release

[gillrogers]

My dinner tonight, home made chilli and rice. Now my chilli has black beans in it. Im trying to get my head around protien and gkucose release delay. Rice is usually notorious for me with a spike. Tonight my bolus, now novorapid, kicked in and down i went fast, libre couldnt keep up and went into sensor error mode and stick tests confirmed it. Looking at the protien carb ratio of the chilli could the protien cause a long delay in release of glucose? This has happened before with anything that has pulses/beans in so im thinking it does and as ive had it happen befire i held back half a unit of insulin to give later. Am i thinking on the right track as i cant think of anythibg else that would have influenced this. Ps its a pudding after the rice that i have every day.

So i stopped the drop with 6gof glucose and that held me steady onmid 7's for an hour and a half then I slowly rose from 9.30pm ish (3 hours after starting dinner) and woke at 2am on 14!! Thats never happened like that.

Sometimes referred to as the ‘pizza effect’, the fat-protein ratio in any meal is important to consider when calculating bolus insulin dosage strategies.

The problem, as I understand it, is twofold. High fat content slows initial carb consumption, with an associated risk of hypo immediately after eating. Protein takes 2+ hours to metabolise, hence the possibility of a second spike starting 2+ hours after eating.

Personally I adapted my own software to calculate a FPU (fat protein units) number for each meal - if that number is over 3 I split bolus, with a final bolus 2hrs after eating.

I hope this makes sense?

Sort of, how do you calculate the fat protein units? Im.sure now ive read this sonewhere but cant remember where. For once im.actually glad ive had this experience as ive now got a rough starting point for this scenario to wort out now as before ive intentionally avoided it as im still learning and didnt know how id react.

I think it was part of my research that I found most useful when adding the FPU calculation to my own software.

If you have software development experience, this is the C# code excerpt from my own software that performs this calculation.

ThankYou littlevoice. I wouldn’t know where to start with the coding or what software to put it in . Tried to work out the formula example in the link you gave me but there’s 288kcal coming from somewhere in its calculation and I can’t see where it’s come from. I ended up a bit lost. I’ll see if I can google something more easier for me to understand. I’ve dealt with the high fat calculation but not one with high protein and high fat.

Ooh good lord, just found another calculator and now know where I was going wrong. There’s no way on this earth my bolus dose would work at those calculations. Based on that fpu’s calculation and using my CIR I would have given myself in total 9 units. But I only needed an extra one unit over night to sort out the mess. That’s a big difference. And I needed to drop a whole unit at normal bolus time and not have the usual bolus to cover the carbs. Oh Lordy .

Ahahah now I remember! So CIR 1:11 = 5.2 on 58g carbs - 20% 4 units at my bolus timing plus 1 unit 2 hours later.
