When I used to eat a regular “healthy diet,” low in fats and moderately high in sugars and starches, I would spend most of the afternoon falling asleep. Now I almost never eat refined sugar, and I eat very little starches, and I spend all day mentally clear and wide awake. I don’t remember the last time I felt drowsy except at bed time.
Well there’s another weird thing that’s happened to me since I started this lifestyle and diet: when I do eat sugar or starches, I don’t get drowsy at all. I have a theory about why this is happening. Given what we know about all the lifestyle changes I have made, I can be pretty certain the my insulin sensitivity is extremely high. I am essentially anti-diabetic. Some of the practices are:
- Cold showers
- Resistance (weight) training
- High intensity interval training (with weight)
- Zero sugar diet
- Extremely low starch diet
- Relatively low carb diet
- Lots of meditation (reduced stress)
- Ketogenic diet
- Intermittent fasting
Having high insulin sensitivity means that my body needs to produce only a very small amount of insulin to regulate my blood sugar, even when my blood sugar goes up a lot. I’m assuming that it can do this more rapidly and with more precision than when it just has to flood the body with insulin, as it does in a body that is insulin resistant and suffers from metabolic syndrome.
According to this theory, even in the face of an onslaught of blood sugar coming from food, my body is able to quickly and efficiently regulate my blood sugar to an effective and adaptive level, without overshooting and making me feel the sleepiness of low blood sugar.
