I have an IR thermometer, which I use all the time. Great for determining oil temp, temp of your pan you want to use to sear steak, how hot your water is, how cold your concrete basement is relative to the 2 inches of foam you added, etc.
I really can’t grasp the relationship between blood sugar and ketones. For instance, the LMHRs tend to have high BS (and ketones), and I thought that was because they also tend to exercise a lot. Makes sense to me that if you’re exercising a ton, high BS would help, say to replace glycogen.
And Shawn Baker at one time had a super high HbA1c, which also made sense to me. That guy is a manimal. He’s not human, really.
But he did something - I’m not sure what - and he’s showing BS in the 50s after exercise. How is that possible?
As for something like the brain, I assume that and muscles get good at using ketones. But all I do all day long is think, and my (blood and breath) ketones are super low. The last blood ketone I took was a week or so ago, in the morning. 0.1 mmol/l.
If my brain uses ketones, why such a low value?
Part of this is because my morning BS is higher, and my ketones are lower. At night, it’s the opposite: BS lower, ketones higher. This is why it’s an “equation” to me: BS + ketones = energy.
But then you look at someone like Zach Bitter. He sometimes runs a marathon every day (on average). He does supplement carbs, but I wonder if he HAS to supplement carbs? How much protein/fat can one person convert over time to blood sugar to help with glycogen replacement (and for whatever else needs carbs)? I assume he’s over that limit.
As for ketones changing, I don’t think they really change that much. Similar to BS, if you’re keto, your BS is pretty stable. I think ketones are similar. I’ve tested multiple times per day, and they seem to not change that radically.
