Is a Potato + butter on a normal western diet the same as substituting a potato for butter on Keto/LCHF diet?
Maybe a question best posed to the Lower Insulin group, but since many of the great minds there are active here as well and out of matter of convenience here goes… My understanding in a “potato skin” is that adding fat to a potato on a typical western diet will give some deceptive BG responses.
Yet the insulin response is increased (de-coupled) suggesting insulin resistance.
Analogous to PIR (physiologic insulin resistance)?
I wondered if this is just a sign of healthy fat adaptation; preference that keeps prolongs elevated BG fueling beta-Cell ATP and or other feedback inhibition absent.
Unfortunately, some variables used to measure insulin resistance aren’t always specific.
Plasma NEFA ought to be considered one of them.
Plasma NEFA also goes up if you fast, but that doesn’t imply fasting causes insulin resistance.
If this has a long term effect, we’d expect that more high fat dairy would be correlated with more insulin resistance (or measures of it). High fat dairy is negatively correlated with insulin resistance. This doesn’t mean the short term effect we are seeing is causing this inverse relationship, but it does suggest that something else is going on that is more important than this.
