This is a common source of confusion, but carbohydrate intolerance is a symptom of diabetes, not a cause. Diabetics that go on Keto diets are still diabetic. If you give them a piece of toast, their blood sugar goes through the roof. It's like that joke about going to the doctor and saying "It hurts when I do this" and the doctor says "Well, don't do that anymore".

On the other hand, eating a whole-food plant based diet can actually reverse type 2 diabetes. People stabilize their blood sugar even while eating things like whole wheat bread, potatoes, rice and fruit, and generally have to have their insulin reduced and then eliminated to avoid hypoglycemia.

There is a theory gaining traction that insulin resistance is caused by fat in our muscle cells that somehow blocks the activity of insulin. So eating a very low-fat diet allows this fat to clear out, allowing insulin to work again, so you can eat carbs without your blood sugar spiking.

The fat in muscle cells is called "intramyocellular lipids". We know that it's associated with insulin resistance, the only debate is whether it's the cause or the effect, or if something else is causing both. Based on what I've read, I subscribe to the theory that it's the cause.

Being overweight or obese is the cause of 90-95% of cases of Type 2 Diabetes. https://www.webmd.com/diabetes/diabetes-causes#1

Being overweight usually is tied to overconsumption of calories. Most people don't consume too much fat or protein: it's just difficult to eat a jar of crisco or an entire ham. However, in western cultures, overconsumption of calories is largely associated with highly processed, sugary foods. Chips, soda, snacks, etc.

I will concede that's not the reason for everyone who is overweight, but for many, it is the case. It's predominantly too many carbohydrates.
