cakes croissants and crumpets - the cause of insulin resistance is fat not carbs

This has actually been known for some time, but there seems to be resistance to it's penetration of general consciousness. A parallel to insulin resistance itself perhaps :)
But study constructions seem to be more willing to look at it from this perspective, for example:

The simple explanation is that intramyocellular lipids inhibit delivery of glucose and oxygen into muscle cells where they are needed as fuel. Consequently glucose remains trapped in the blood where it creates problems, often leading to type 2 diabetes, and further complication; or other problems entirely, of other types.

High intramyocellular lipid levels is caused by high blood lipid levels which is caused by high fat in the diet.

Understanding this mechanism helps to understand why a plant based diet composed of approximately 80% of total calories coming from carbohydrates reverses type 2 diabetes so quickly and efficiently.

It will also help to understand how people on a diet where 80% of total calories come from carbs are also the leanest population on the planet (a population that is also perfectly healthy, ie not anorexic or malnourished in some way).

Carbs do not make us fat! It's a myth promulgated by a culture that has become dependent on distribution of calories in concentrated form (fats) for reasons of economic efficiency. Nothing wrong with economic efficiency as long as it does not become counter productive to the health of populations. Health is wealth not only for individuals, but also for populations.

The cheapest, densest, most easily distributed calories ever are vegetable oils (which are pure 100% fat). They are also empty calories, and their value as nutrition is exactly proportionate to their very low cost.

Let me add a final point to define "carbs" lest one think I'm referring to cakes croissants or crumpets, which are "foods" (using the term loosely) that derive more energy from fat than carbs, and is how we as a culture became so confused and misinformed as to what a "carb" is. These toxic substances, yep the ones we are addicted to, those ones, have carbs in them, but also have fats in them. And the fats, being such a concentrated source of calories, actually predominate the caloric composition of these food-like toxic substances.

So cakes croissants and crumpets are more accurately called "fats" than "carbs".

When I use the word "carbs" in the context of a diet composed of approximately 80% of total calories coming from whole plant carbohydrates, I am simply referring to the many tens of thousands of plants that are edible by humans in their whole natural form.
