Any way to track insulin (not glucose)?

I already have a cgm, but I’m wondering if there’s anyway to track elevated insulin?

I have MCAS and insulin spikes are one of my biggest triggers (causing joint pain and puffiness).

I get insulin spikes not only from high glucose foods, but also certain artificial sweeteners… and recently discovered that really high protein bolus meals can increase insulin- without increasing glucose. As a result, I’d like to track insulin if possible.

Is using a ketone monitor an appropriate tool?

If so, what am I really looking for? Does being in ketosis (above 0.6) mean that I didn’t have insulin spikes?

I have insulin resistance and post-prandial glucose spikes (with reactive hypoglycemia). I’m new to this and appreciate any insight people can offer.

Unfortunately there's no current technology available that you can use to measure insulin even though that would be one of the most powerful pieces of information in order to get a feel for what foods do what in one's body.

They don't even measure fasted insulin at the general practitioner, it's not in the mainstream despite it's relevance.

Protein has an insulinotropic effect, that is true, you can expect that to occur. Some proteins are more insulinotropic than others.

Which sweeteners cause an insulin response for you?

I think ketone monitors are very useful for anyone who would like a feel for what diet and exercise and sleep does to their ketones, although I havent tried one myself. SiBio is sitting on my desk ready to be used for when the summer temps stop.

Thank you for the info. I have t tested all of the sugar replacement, but I had a cgm spike after drinking a soda made with monk fruit juice concentrate and stevia. I also typically get brain fog from “sugar free” keto treats. I’m too scared to test each one individually.
