It doesn't make any sense.. The body is designed to use sweat to cool itself.. Lack of sweat is the main symptom of very slow metabolism and vice versa people with fast metabolism sweat easily.. I think that there is happening some serious adaptation to whatever is going on in your body. Nevertheless it is interesting experiment. It would be cool if we could see more extensive blood work. But I understand that it is expensive in your country..
Not necessarily true , I have a body temp of around 36.7 normally and during evening and after I eat it goes 37 C sometimes beyond.
I have a very fast metabolism and I don't sweat a lot . I can handle heat and cold well . Also , I don't know where co relation between the idea of not gaining weight easily i.e. fast metabolism and good health came from .
Retaining muscle mass and gaining some weight i.e what we call as slow metabolism in science could very well be form of an efficient metabolism . Think about it from an evolutionary perspective , I wouldn't survive longer in the wild . I will have to eat constantly to survive where as a person with "slower metabolism " would just do fine
PS: I have a relative , he is fat and as per your rationale he should be having a slow metabolism , but he sweats like anything.

Sweating is a stress-reaction and is caused by estrogen-signalling. It is why menopausal women have waves of sweating and night sweat in seriously ill people. Im not saying we dont need to sweat - the body needs the ability but it is still regulated by stress-reactions. I have personally found my sweating to finally decrease after several years of increased sweating and find it definately to be a sign of health. I feal much better and now dont sweat much at all if i strength train. The important thing here is to not confound sweating and fealing of heat with body temprature. These are mechanisms in place to help regulate body-temprature but are not directly reflective of body temprature. Many hypo-thyroid people will struggle with excessive sweating. Its normal for people to feel hot while having a lowered body temp. So I assume basically the body works better with less stressors and thus dont call for excessive corrective measures.

It's well known in veterinary science that VAD is a big problem during reproduction.
"Clinical signs of both vitamin A toxicity and deficiency include absorption of fetuses, abortions, stillborn kits, decreased litter size, low neonatal viability, and hydrocephalic kits. Vitamin A deficiency (hypovitaminosis A) can affect cartilage formation in rapidly growing rabbits, which present clinically with droopy ears (5)."
"Vitamin A deficiency can present with many different clinical signs, but the most common signs are weak or stillborn calves. In this article, we will discuss some possible reasons why this may occur in our spring-calving beef herds."
It's incomprehensible to me that a health practitioner is advising that vitamin A isn't a vitamin.

Pretty significant stuff.
Can you post their testimonies?
"Not at all. I’m just looking at and seeing the facts. Something you are apparently completely unwilling to do. And, the “it’s a vitamin” claim is now a complete joke! Please see my latest update."
Why are you responding to what Jiri wrote as though it's from me?
"A scientific fact is that the lowest rates of birth defects in the world are in regions with endemic “vA deficiency”."
Countries that have lower intakes of vitamin A may have lower rates of birth defects. That doesn't mean that lower rates of birth defects occur in women with VAD than in vitamin A sufficient women. Also, birth defects are not the only concern, still births are another.
"Same here, there have been a few mothers here following a very low vA diet, and they’ve had perfectly healthy babies while doing so."
Following a low vitamin A diet doesn't automatically mean VAD. Liver and serum levels may still be sufficient. But even if a few VAD women had healthy babies it doesn't say much about risk.
"But, we already know what actually does go wrong with vitamin A supplementation.
- Significantly increased rates of birth defects (like 2X)
- Significantly increased rates of childhood deaths (like 17X)
- Bulging fontanelle (inflammation on the brain)
- xerophthalmia "
What does this have to do with the risks of VAD especially when xerophthalmia in the third world may often be caused by malnutrition and deficiencies of protein, zinc and riboflavin rather than just VAD? With the understanding of what high dose vitamin A supplementation would do to a malnourished pregnant woman's folate status for example one can appreciate that the situation is far more nuanced than just concluding that because supplementation may cause harmful effects in this situation that VAD is a good thing!
Hypervitaminosis A does not cause xerophthalmia. Hypervitaminosis A and Accutane can mimic the early stages because high levels of retinoic acid can inhibit enzymes needed for retinal utilization in the eye.
Corneal ulceration (Grade X3A and B): Corneal xerosis can lead corneal ulceration and melting if not treated urgently. Keratomalacia, the melting away of the cornea by liquefactive necrosis, is the most severe form of xerophthalmia. It can perforate and destroy the cornea in just a matter of days. A child who appears relatively healthy but develops keratomalacia should be questioned about a recent history of measles or diarrhea, which could rapidly deplete already deficient vitamin A.
That's the end stage of xerophthalmia. Show me one case where that's happened due to Hypervitaminosis A.
@r-2 "PS: I have a relative , he is fat and as per your rationale he should be having a slow metabolism , but he sweats like anything."
You can have fast metabolism and be obese if you simply eat too much.. Now if you are obese and you eat very little that is slow metabolism.. Many woman who are doing all kinds of weird diets have this issue..

This person I know doesn't eat much at all , yet he is obese . I eat so much yet I am skinny . The scientific notion of fast and slow metabolism is just a reductionist approach for something very complex
I hold the belief that excessive perspiration might not necessarily be conducive to one's well-being, given the resultant loss of vital electrolytes. Additionally, I have encountered literature suggesting that one of the mechanisms for the elimination of toxins and Vitamin A from the body involves processes such as bad breath and perspiration. Consequently, it could be inferred that an increased frequency of perspiration potentially contributes to a heightened excretion of Vitamin A. This theoretical assertion could potentially rationalize the observed phenomenon wherein I experienced an expedited recovery period during my engagement in Mixed Martial Arts activities conducted under elevated temperatures of 40 degrees Celsius. It seems plausible that an elevated volume of perspiration corresponds to an escalated excretion of Vitamin A, thus elucidating the accelerated recuperation I underwent during the aforementioned circumstances.
@r-2 you can detox all kinds of things by exercise. Gbolduev was talking about this all the time. In my worst point I was doing nothing, because I was believing that you have to just stay home and relax to heal adrenals etc.. But if you are already toxic and you slow everything down in the body. You will not detox anything obviously.. By increasing adrenaline during exercise you dump all kinds of toxins.. Btw nobody is talking about excessive perspiration is healthy. Normal sweating is healthy. If you are o the sun in 35 celsius it is completely normal to start sweating as your body temperature rises. Detoxing in the sauna is great example. Every single person will tell you that in their worst they couldn't sweat at all in sauna and as their health improved they started sweating more easily. When I was insanely hypothyroid I couldn't sweat at all. Healthy people sweat(during times when their body temperature goes up from exercise or hot environment) from all pores on their body face, legs, hands, fingers.. To say like somebody here that sweating is just stress reaction from estrogen etc.. you can't compare sweating from hot flashes during the night to sweating from sauna or exercise lol...
There are a couple of things that appear to me
- We best not wait around for science to catch up, (thanks to Wavy for explaining just how big a project that will be) we will be long gone by the time that happens (if ever)
- It appears that several smart people here think that small amounts of VA might be needed for various things in the body (I for one suspect that VA's might help fight infection)
- It also appears that many (most) people here believe in vitamin A's toxicity at high levels (and so does science, as they know polar bear liver is toxic)
- If I was going to have a baby, I'd hedge my bets on the side of low amounts of vitamin A (not zero, not high and not supplements). (this is how my Northern European ancestors ate)
- Grant's updates always lead to vigorous discussions!
