The study by researchers at the Weizmann Institute of Science in Isreal used continuous glucose monitors to measure the BG levels of 800 healthy and prediabetic people after their meals for a week, and put this information along with what they ate, information from stool samples, and other physiological information into computers and analyzed it. They even gave them identical foods for some of their meals.
What they found was that the people differed greatly in how they responded to various foods; the glycemic index, a measure of how much your BG levels are supposed to rise after eating carbohydrate, varied among the participants. “In some cases, individuals have opposite response to one another, and this is really a big hole in the literature," said Eran Segal, the lead author of the study.
"After seeing this data, I think about the possibility that maybe we're really conceptually wrong in our thinking about the obesity and diabetes epidemic," he added. "The intuition of people is that we know how to treat these conditions, and it's just that people are not listening and are eating out of control--but maybe people are actually compliant but in many cases we were giving them wrong advice."
I also don't lose on keto/LCHF/under 50g of carbs, but others are 100% opposite. It's so weird how different we all are.
