There are a lot of words in that article that are beyond my understanding. My personal experience is I developed insulin resistance by eating too much candy, cookies and pastries. It usually turns out that articles like that confuse fat and sugar, that they almost never give the rats or the people a diet that actually separates the carbohydrate from the fat. And they never give the rats or the people real fat. They usually give them manufactured fats like soybean oil, not grass-fed butter. My personal experience was when I dropped the carbs and the manufactured fats and started eating grass-fed beef, butter and cream, pastured eggs and chicken and green vegetables slathered in animal fat, coconut oil or butter with only an occasional bit of sweet potato for my carbohydrate portion, my insulin resistance became a non-issue and I lost weight and feel 1000% more healthy.
