Dr Joseph Kraft did a lot of work on insulin. Basically we all have a baseline level. When we eat, it goes up to try to convert food to blood glucose. When we eat sugary food (a.k.a. carbs) insulin goes up more. When we eat low carb, it still spike but not as high. Then it tapers back down to our normal level. For some people that normal level is way high. For others it's normal but it takes a lot longer to come back to it. Dr Kraft laid all that out.
Long and short of it is that low carb does spike insulin less than carby food. Fasting is even better. And if you can keep your insulin levels lower for a while, that normal "baseline level" you walk around with starts to get lower too. That's when you are really flying high. Fasting is the best way to that.
I got all my levels completely under control using intermittent fasting. I became a zealot to the cause. I still am. Yet I've fallen off the wagon. I am trying to get myself back on now. Since falling off, the weight is coming back and I assume the internal damage is also. Articles like this remind me how what I was doing wasn't just about losing weight, it was about reducing risk of cancer, diabetes, and a slew of other conditions. Time to get real again!
I’m thinking once the diabetes is cured, I’ll continue fasting for a time to lose more weight. And then I’ll switch to periodic fasts, such as a week every two months.
