Most of the studies you cite to support your "belief" that low carb diets are superior have similar problems: they also change protein content, vitamin levels, etc. without controls.
It depends. On a low carb diet, protein is not really changed (low carb should be a moderate protein diet) but carb content is reduced while fat content is increased. Of course, the nutrition one gets changes, as a result and indeed it is not perfect as more than one thing changes. I agree. Some studies have a control group whereas others don't. But, at least these studies aren't simply observations where people are followed, asked what they ate and then an association is made between what they ate and heart disease or cancer rate when so many factors can differ between these two groups. These studies are much more tightly controlled with much less confounding variables. Some of the studies I provided are indeed randomized controlled trials and these are much more solid than cohort or epidemiological studies for obvious reasons that I explained many times before.
The following 24 studies are all randomized controlled trials, one of which is a systematic review:

Quotea rational vegan will supplement it just like a rational strict carnivore would supplement vitamin C.
I earlier showed you a study where men ate an exclusively meat diet for one full year without Vitamin C supplement and showed no symptoms of vitamin deficiencies. You choose to ignore it. I provided information on the lack of scurvy in Inuits who practically eat only meat and fat all their lives and how raw meat cured some sailors and explorers of scurvy. I also myself lived on only meat and nothing else for more than one year and developed no Vitamin deficiency. This sort of deficiency would start kicking in quite quickly and it hasn't in people following a strict carnivore regimen.
QuoteMales are MUCH less likely than females to suffer from breast cancer, but you would not tell that to a man with breast cancer; would you?
Breast cancer is indeed much less likely in men. I never said ABSENT, or that scalp hair loss in women was unheard of but LESS LIKELY.
QuoteAdding more E or bicalutamide would cause very real side effects for me, much worse than dutasteride. lhrh agonists are very expensive. And none of those three methods would suppress DHT as effectively as dutasteride.
I didn't realize you had orchiectomy so LhRh agonists are useless. I understand about the estrogen. But, have you ever tried taking bicalutamide? What were the side-effects? Bicalutamide would block DHT very effectively, it is used in men with prostate cancer with castrate levels of T.
QuoteNormal is the range of a menstruating cis woman.
You don't consider pregnancy normal? Traditionally, women became pregnant several times during their lives and spent most their reproductive years being pregnant or breastfeeding. I consider pregnancy actually more normal than fluctuating levels every month and suspect women were traditionally exposed to much higher levels of E for a longer time than they do now.
I disagree. Pregnancy is indeed VERY normal.
QuotePregnant women's levels do not crash by 1000 or more every week. Such rapid and frequent fluctuations of such large magnitude are not within the typical female experience and I think most women would not do well emotionally with such wild changes.
Many transwomen report feeling BETTER on injections, usually taken weekly, than on orals where levels fluctuate much less. Most women actually do fine despite these fluctuations as long as interval is kept to about a week. You are deeply mistaken in that respect. I do well, have no emotional ups and downs. Your situation is not the norm.
QuoteI can think of several: extreme constipation, candidiasis, blood clots, estrogen-positive cancer...
I have high levels of E and my clotting times have remained perfect. Pregnant women have extremely high levels (up to 75,000 pg/ml) and despite this, their risk of thrombosis remains under 0.2% (largely in women predisposed) whereas risk increases post-partum when levels crash. Studies in men with prostate cancer (aged up to 91 yrs old, average age 75) have shown high levels (up to 700 pg/ml) not to increase risk of clots and to actually protect against it. A study found no incidences in transsexual women taking very high doses of IM EV. I have several times provided the references/studies for these. Just look back through my posts.
I have never heard of either a link between estrogen and constipation and candidiasis. I have neither of those despite very high levels and have never read any such report from transwomen on high levels, expect perhaps you. Can you provide actual scientific support for this?
Cancer is very low in transsexual women despite for decades, being prescribed sometimes VERY aggressive doses of estrogen. Pregnancy, a time of very high levels of E, has been inversely associated with breast cancer in ciswomen and in randomized controlled trials, estrogen taken alone or without progestogens known to increase risk of breast cancer, has actually neither increased the rate of cancer and even reduced incidence. Even in women with prior breast cancer, studies have shown either no recurrence, low recurrence or less recurrence on estrogen. High doses of estrogen are sometimes actually prescribed to women with advanced breast cancer and one such study even found E to be better than tamoxifen, an "anti-estrogen", in terms of survival rate. Overall, it seems that estrogen is more protective than anything else. Women get breast cancer after the age of 40 and especially 50 when their estrogen levels drop.
Pathol Oncol Res. 2012 Apr;18(2):123-33."even a slight decrease in their circulatory estrogen levels associated with insulin resistance may increase the risk for cancers, particularly in the organs having high estrogen demand (breast, endometrium and ovary). On the other hand, postmenopausal state with profound estrogen deficiency confers high risk for cancers in different organs with either high or moderate estrogen demand. After menopause, hormone replacement therapy improves insulin sensitivity and decreases the enhanced inclination to malignancies in postmenopausal women."
Journal of Clinical & Translational Endocrinology 2 (2015) 55-60"There is no increase in cancer prevalence or mortality due to transgender HT."
"While some guidelines for transgender medical care express concerns for elevated cancer risk with certain hormone regimes, current data suggest that the risk of cancer may not rise."
"Although studies are small, overall cancer incidence in transgender men and transgender women to-date has not been found to be different than their respective male and female controls [5].
There are no reports of change in breast cancer specific risk among transgender individuals on estrogen compared to secular trends of male breast cancer incidence.[/u] Rates are lower relative to secular trends of female breast cancer rates."
