So I was reading up on an article about how low-gi foods can be misleading because of the insluin that STAYS elevated or traveling around the blood for hours on end doing damage after secretion. Then I wondered, why not tackle this Insulin problem by not just secreting a lot via blood sugar (hence don't eat stuff that releases insulin), but ALSO stop it to STAY in the blood like forever and a day. And that brings me to the question - Where exactly does Insulin go after it's done it's job and what makes it go there? Can't THAT process somehow be triggered earlier somehow so one can get rid of it earlier. Or is the article wrong by stating that Insulin sometimes stays in the blood for hours on end AFTER being secreted.

I can understand the merits of low-carb diets because they seem to reduce the need for insulin. I think low-carbing is essential if your metabolism is deranged or is in the process of becoming deranged. The latter describes most people in the U.S. who consume Neolithic agents such as gluten grains, plant oils, and granulated sugar/fructose.
However, here is the apparent paradox. Those indigenous culture and tribes who subsist on tubers have beautiful metabolism. I mean, their glucose tolerance is so much better than Westerners, who similarly eat a carb-heavy (albeit Neolithic) diet. I'm talking about (1) the highlanders of Papua New Guinea; (2) the Bantu of the Central African Republic; (3) Latin America's cassava-eating tribesmen; and (4) the Kitavans of Polynesia. Stephan Guyenet mentions these tribes in his blog:
So here's the part that I don't understand, which I hope Dr. Quilt (or anyone who proposes eating 50g of carbs or less) can answer. How is it that a carb-heavy diet can promote such beautiful metabolism? Granted, these indigenous cultures are not eating Neolithic agents. However, if you eat tubers like yams, potatoes, and yuca, insulin will be deployed post-meal and WILL SPIKE to deal with skyrocketing BG, even in those who are healthy. How is it that these peoples can keep their FBG so low? Unlike post-prandial insulin spikes, the fasting blood sugar does indicate the health and state of your metabolism.
Wouldn't the serum insulin level in these people be higher than in the Inuits or San Bushmen (another traditional culture that ate low-carb)? I mean insulin will spike at least 3 times daily in these peoples, compared to slight insulin rises in the Inuits after protein consumption. Btw, Stephan believes that post-prandial insulin spikes do not contribute to obesity (I would go further and conclude that they do not harm metabolism nor contribute to the onset of chronic and degenerative diseases).
So I fully understand the merits of low-carbing. However, it seems that you can stay perfectly healthy by eating a carb-heavy diet, as long as you steer clear of gluten grains, sugar, and other Neolithic agents. There WILL be insulin spikes. But they don't seem to cause any harm as long as you avoid the aforementioned Neolithic items. So what am I missing?
