ALLOPREGNANOLONE, produced from Progesterone by an enzyme called 5-alpha reductase and one called 3-alpha HSD, in both Neurons and Astrocytes, is the most important of the neurosteroids. Allopregnanolone production, facilitated by PEA (PalmitoylEthanolAmide), is the reason why PEA is recommended as a painkiller, as well as its sleep-promoting and mood elevating effects.
Wikipedia describes Allopregnanolone as (I quote) “stress reducing, rewarding, prosocial, anti-aggressive, pro-sexual, sedative, sleep facilitating, pro-cognitive, memory enhancing, analgesic, anticonvulsant, neuroprotective and neurogenic”.
I call Allopregnanolone“the brain’s housekeeper”, because it is the main actor in brain maintenance and repair.

This just in, from Medscape medical news: an excellent article, entitled “Experts Aim to Use Brown Fat to Burn Fat More Effectively”, by Ute Eppinger, on March 29, 2024.
This is a very good article, which you may wish to read (click the link above). It claims that (more or less) all you need to do for obesity is to activate the brown fat. It goes on to suggest the use of Mirabegron, which is quite safe and actually, a very good medication.
However as usual, this is a synthetic medication, prescribed without any thought as to the origin of obesity’s underlying problem and with no effect on other aberrations, apart from obesity, caused by the underlying problem: this is the usual “tack” of Allopathic medicine: treatment to eliminate symptoms, without affecting the disease.
The cause of underactive brown fat, and therefore of obesity, is of course, a reduction in the quantity of thyroid 3 (FT3) available to it. Brown fat is activated by a combination of T3 and Noradrenaline: Noradrenaline is supplied in adequate quantity by the sympathetic nervous system; but stressed humans develop “Intracellular Hypothyroidism”, a.k.a. “Low T3 Syndrome”, in which their cells convert T4, the thyroid Hormone, into reverse T3 instead of normal T3. When that happens, There is not enough T3 in the serum and the brown fat, starved of T3, stop working.
Mirabegron is safe and costs less than C$2/tablet. Big Pharma would like us to prescribe it, on the basis that it stimulates brown fat and reliably causes some weight loss. However the drug, as usual, treats symptoms, not cause: it is a treatment of the end result of a pathological condition, not a treatment of the condition itself.
So Mirabegron, although effective in getting rid of the obesity, does nothing to eliminate the T3 starvation which caused the obesity by shutting off the brown fat and it does nothing to help the other symptoms associated with Low T3.
The cause of obesity is explained in my two posts on brown fat (1) BF & O and (2) “More, on Brown Fat”. Brown fat is activated by the combination of T3 and Noradrenaline (from the sympathetic innervation of brown fat). Noradrenaline without T3 does not activate it and T3, without noradrenaline, doesn’t activate it either.
You can get a handle on whether an obese person has the low T3 syndrome by checking the thyroid profile, including TSH, FT4, FT3 and rT3: that is explained in another post: how to diagnose intracellular hypothyroidism (a.k.a. “subclinical hypothyroidism”, “Low T3 Syndrome (LT3S)” and “nonthyroidal illness”.
So if you examine an obese person and find that he or she has a low body temperature, you should test for FT3 and rT 3 together: if the ratio between serum FT3 and reverse T3 is over 20, you will have diagnosed the low T3 syndrome.

Hereunder is an autobiographical report of my own medical history of chronic stress-related Intracellular Hypothyroidism (IH). I describe a 43-year history of steroidopenia and IH, which began at age 40. The step-by-step evolution of the syndrome is laid out chronologically, the eventual cure is explained with reference to detail via my “SUBSTACK” blog and a few supporting references are provided.
This post is rather long, because the chronology and the step-by-step progression of the illness described, is of importance in understanding “the bottom line”. If you find it “too much”, scroll down to “retrospective analysis” and read from there, to the end.
This history is put forward without intent to compromise known and accepted methods of management and without a plan to profit in any way from its publication. My intent is to assist others in the prevention or alleviation of this condition. I offer it in the interest of furthering my colleagues’ knowledge of the syndrome from which I suffered for 40 years.
I was born in Montego Bay, Jamaica, in 1939. I was blessed with an extraordinarily stable, supportive and appreciative family, who encouraged me to dependable self-confidence and self-reliance and rendered me extremely steady, stress resistant and subjectively tranquil. I am not subject to “anxiety” as such and have never been depressed. However as one bordering on the autistic spectrum, who instinctively examines all possibilities prior to conclusion and decision, I am admittedly subject to mild apprehension – “Id–perceived stress” – in uncertain times and in ill-defined circumstances.
Thus, as all humans do, I increase my cortisol production in response to perceived stress, thereby reducing the rate of (intracellular) conversion of thyroid 4 to thyroid 3, and I must suffer the consequences.
In my case, it took 40 years for chronic stress to “come to a head” and my eventual cure was a matter of good luck, in addition to good management.
The lesson here is that stress is responsible for many, if not most, Illnesses and that there is a way to circumvent and/or eliminate its effects.
