I am trying to find out whether fiber turns into glucose in the body as Dr. Westman states or whether fiber has no effect on blood glucose as Dr. Rosedale states.
My partner was reading Keto Clarity and showed me this rather strange paragraph: DOCTOR'S NOTE FROM DR. ERIC WESTMAN:
"There is often confusion between counting "net carbs" and "total carbs." "Net carbs," determined by subtracting the fiber grams from the total grams of carbs, works well for those who are not very rnetabolically sick or who don't have much weight to lose. But because some of the fiber is absorbed as glucose and your goal now is to become ketogenic, the more prudent approach is to not subtract even the fiber grams from the total grams of carbs."
This flies in the face of my understanding, said in The Rosedale Diet book by DR. RON ROSEDALE:
"A more useful classification of carbohydrates is as either fiber or nonfiber carbohydrates. High fiber carbohydrates are found mostly in vegetables and nuts. The major advantage of fiber is that it can’t be broken down into sugar, which means that it doesn’t raise blood sugar levels or send your insulin and leptin levels soaring. In fact, only bacteria (including some that inhabit our gut) can digest fiber at all, and they di- gest a type of fiber called soluble fiber into good fats that are used for energy by the cells that line our intestines."
Can anyone shed some light on this apparent disagreement? I'd really love to know all the possible metabolic pathways for fiber.
