Why insulin resistance is good

We’re always told that insulin resistance is the root cause of diabetes type 2. But that may be wrong. Insulin resistance could be a GOOD thing.

Dr. Fung explains it well in this insightful new post. Basically, insulin resistance is the way the cells protect themselves from excess insulin and glucose in the blood (the real problem):

Dr. Fung: Insulin Resistance is Good?

I love Dr. Fung’s take on inflammation in this post as well. It has bothered me for quite some time when people claim that inflammation is the cause of X (i.e. heart disease). Inflammation is usually a symptom of a problem, it’s the body’s default response to damage. The cause is something else.

In the case of heart disease the cause is damage to the interior of the blood vessels. This damage results in inflammation – but that’s just a symptom. The cause of the damage? Many things. High blood sugar. High blood pressure. Toxic chemicals (e.g. from smoking). And probably oxidized small dense LDL particles.

Excess bad carbs can be behind all these causes of heart disease, except perhaps smoking.

The thing is that we can’t solve the problem by attacking a symptom of the problem. Diabetes type 2 can’t be cured by targeting insulin resistance. Heart disease can’t be cured by targeting inflammation.

We need to take away the cause, which in many cases is eating too many bad carbs, too often (a normal Western diet).

    I think what you are saying is this: you cannot blame the fire fighters for stomping all over the flowers in your garden while they were trying to put out the fire raging through your house.

    I think IR evolved as an adaptive mechanism for nutrient partitioning, where it takes different values at different tissues. Whole body IR is used to rapidly store a glut of food. This physiological IR works very well as long as it is then switched off when no longer required.

    Modern diets switch it on chronically and lock it on. This is NOT adaptive.

    If this were so, why does Jackie Eberstein continually have to reduce hee carbs? She's been LCHF & IF for decades. And she's thin too. IR cannot be so easily cured, we have many exsmples. Still you have no theory of IR our own friends doedn't disprove. :(

    Please expand on how insulin resistance is used to store energy.
    Isn't it the other way around, it prevents storage?
