Imagine you're not in ketosis. A stretch for some of us, I know.
You're full of glucose. Coming from sugar, coming from starch, stored as glycogen.
You're full of glucose. So you're trying to burn glucose instead of fat.
But you can't burn glucose.
Your metabolism will run slow.
Your basal metabolic rate will be low.
You might even have trouble maintaining your body temperature while asleep.
That last one, if it's true, would be terrifying.
All the chemical processes of the human body are designed to run best at the temperature of a human body. And tuned precisely to that temperature. Change it, and the various speeds of the various reactions will shear. Nothing is going to work quite right.
That core temperature is homeostatically defended. If the literal thermostat that controls your body temperature can no longer get it up, then that implies that your metabolism is in a very bad way.
If you go into ketosis, your emergency back-up fat and ketone metabolism should work properly, and your core body temperature should rise.
A long time ago now, I came upon the writings of Broda Barnes, whom I initially wrote off as a lunatic.
https://en.wikipedia.org/wiki/Broda_Barnes
I have a copy of his book: Hypothyroidism, the Unsuspected Illness.
https://www.amazon.co.uk/Hypothyroidism-Unsuspected-Illness-Broda-Barnes/dp/B000BOB2WK
Over the years, I've seen that a lot of the things that book said were true are, in fact, true.
Forgive me, Dr Barnes. You were a brave, clever and careful man. You saw what you said you saw.
You were wrong about the cause, but anyone would have been.
Broda Barnes was a pre-war endocrinologist who was interested in thyroid disorders.
He decided, on very good grounds, that the best way to measure basal metabolic rate was to measure waking temperature.
He tested literally a thousand healthy young men to get his standard waking temperature of 36.7C/98F.
He thought the standard variation was +/-0.1C, +/-0.2F.
That is to say, he thought that if your waking temperature was less than 36.6C/97.8F then that meant that your metabolism was slow enough that it meant you were ill.
Very few people these days have a waking temperature of 36.6C.
Broda thought we were all hypothyroid. That's the bit that he was wrong about.
We've all been poisoned by polyunsaturated fats.

Wiki says:
Barnes believed that many common diseases, including heart disease, cancer, depression, arthritis, diabetes, the common cold, tonsillitis, ear infections, apparent laziness in children, various menstrual disorders, and skin disorders, were all caused or exacerbated by hypothyroidism.
He was probably right about all that. I dare say that they are all caused or exacerbated by polyunsaturated fat poisoning as well. The symptoms are very similar, in general.
One of the facts that everyone used to know about the human body was that the right temperature was 98.6F/37C.
They used to teach it in schools.
Nurses used to plot temperature charts for hospital patients.
No-one is telling me that the Victorians couldn't measure temperature accurately.

https://en.wikipedia.org/wiki/Human_body_temperature
In humans, the average internal temperature is widely accepted to be 37 °C (98.6 °F), a "normal" temperature established in the 1800s. But newer studies show that average internal temperature for men and women is 36.4 °C (97.5 °F).

Everyone is running cold, poisoned by polyunsaturated fats.

Not entirely unsurprisingly, there's them that say that basal metabolic rate has declined over the last century.

Crisco was first sold in 1912.
“What was garbage in 1860 was fertilizer in 1870, cattle feed in 1880, and table food in 1890.”

I don’t blame Proctor, or Gamble. We didn’t know the first damned thing about biochemistry in 1912. How were they to know the horror they were unleashing on the world?

Got this by email:
THANK YOU FOR POINTING OUT ABOUT THE TEMP IN KETOSIS.
my basal temp can run SO LOW but I note if I stay in ketosis (T2D now unmedicated thru keto) my temp stays up around 97 in am.
can go into 95s. the ketosis thing makes SO MUCH SENSE to me ........
I am going to do a deeper dive into my ketone levels vs my basal temp.
thanks again
