Insulin Genetic Factor

Nutrition
1

I came across an article (that I can’t post here) that stated the amount of insulin people release after a meal can be 10x different than the next person, as in, some people release 1 unit, some 10. Even when eating the same amount of carbs,fats,protein during the meal. This is what they referred to as the Genetic Factor.

They also showed how in some studies, the lab rats who released more insulin per meal did best on HIGH FAT diets. Those who released the least amount of insulin per meal did best on HIGH CARB meals. This is in terms of fat lost on a “diet”.

My question is, how can one determine how much insulin one’s body releases? I don’t mean specifically for meals, but, how can I know if I generally release a lot or a little?

Did the article cite a study that found this at all? If so you can most likely link those.

But my guess is that, for non-clinical ways of measuring, would be to ingest a certain amount of carbohydrates, and check to see how you feel about an hour after ingestion. I would think that the more Insulin you produce, the more tired you would be due to the brief low-blood sugar period where the Insulin mops up glucose.

Those who produce less Insulin would probably have more stable blood sugar levels and have it mopped up at a slower rate, thus avoiding any significant crash.

And ANY sort of link or reference to that article or study would be appreciated.

The article was written by Lyle McDonald, actually. He has some articles on TMuscle right?
