does anybody know if a certain insulin type is better for those who are following a low carb higher protein/fat diet. i know protein and fat convert to glucose slower which is why i am wondering if novolog would be the better insulin for me. Apidra is fast acting and seems to leave my system a few hours after the correction and coverage.
From my experience with novolog, it works very well for me with my low carb diet. I eat an average of 40g of carbohydrates a day and most of those are fiber carbs, Anyway, you should experiment and see how it works for you, Most of my Type 1 D-Friends using apidra tell me its the perfect insulin for High carb and high sugary meals because it knocks out that spike perfectly. if you're on a high fat diet (low carb) Novolog has that lasting effect we need ;-) as long as I've been doing the low carb I had no issues. Except for when I try to bolus for Cheese (i love cheese!), every type 1 knows cheese is a pest when it comes to its looong lasting affects :-)
I use Apidra & Regular on low carb, using split bolus doses (MDI). I have gastroparesis & need slower acting insulin that stays around, though I can see how Regular would be helpful for low carb without delayed digestion. You sure don't want to use R to correct highs:)
Like Desiree I experience that the NovoLog has a rapid onset combined with a longer tail. But you have to find that out for yourself. The fastest analog Apidra is for some people like water and for most it is a blessing. The reason is not know to me. It could be caused by some individual differences in the insulin receptor or the environment of the receptor or the body chemistry in general.
We often test at fixed times after meals, and while this may be a good strategy for deciding whether to correct, it doesn't help us answer questions about how well our insulin has matched our meals. And as you and others have noted, low carb, high fat/protein tends to result in meals that have a glucose curve over 2-4 hours rather than 1-2 hours.
So it may be good to just do some "experiments." Eat a typical low carb meal and test at 1hr, 2hr, 3hr and see how well your insulin matches your meal profile. You can adjust your insulin timing (I actually often take my humalog at my mealtime rather than 15-30 minutes before). Your dose should result in a return to preprandial at 4-5 hours. But if you are back to preprandial at 2hrs and you still have food remaining to be digested, you may have some mismatch. Some people split their insulin shots, half when you eat and another half a half hour or hour later. But mostly, your glucose curve should be your guide. The key indicator that the insulin is just too fast is going hypo at 1-2 hrs and then rising back up at 2-4 hours.
thanks everybody, always so helpful! i'm going to ask for a sample of novolog at next weeks appointment. hope everybody else is doing well!
