I was reading a post, “Gary Taubes and the Cause of Obesity” on a site called ScienceBasedMedicine. The author, Harriet Hall, said:
“… serum insulin levels are driven by the carbohydrate content of the diet.”
Many people think this. As you know, it is inaccurate. Dietary carbohydrate is not the sole driver of serum insulin. But it persists in people’s minds. It is the reason people go on low-carb diets … thinking they can reduce their blood glucose and insulin by eating fewer carbs. Unfortunately, that means eating more fat and…
High-fat diets have been shown to increase insulin levels, because fat (especially saturated fat) can decrease insulin sensitivity. When cells become resistant to insulin, the pancreas produces more insulin to compensate, resulting in high serum insulin levels or hyperinsulinemia.
Also, when cells becomes resistant to insulin, glucose in the blood can’t enter cells so blood glucose levels rise.
Here’s an unfortunate result … high insulin levels can feed insulin resistance, which can feed high insulin, which can feed insulin resistance … in a self-propagating manner:
That quote in my title, “Fat Affects Your Blood Sugars” came from this video out of the Joslin Diabetes Center. People think it’s just the carbs that affect blood sugar; it’s the fat too:
