>>3This. Since following some of Ray Peats findings i feel so much more energetic and i still consider them day-to-day despite having a relatively starch-heavy diet for budgetary reasons.
Most people building off of his work should be taken with a huge grain of salt though. As a tranny i had to confront a popular bugbear in the peatarian community, which is the role of estrogen in metabolism. It is often claimed that high-estrogen lowers metabolism, even though i found no studies attributing these to estrogen alone. One study even indicates estrogen accelerates metabolism! The theory about low estrogen/high progesterone being an indicator of female health is first directly connected to the supplements people on raypeatforum liked to push and second to the effect of *tissue-bound* estrogen, also called aromatase, which forms in response to *falling* levels of free estrogen. I'm not surprised to have seen the forum pivot hard to a vitamin a diet, that seems even shakier than keto, for no discernable reason other than selling new supplements.
From my own experience, having adult-woman levels of estrogen is a non-factor next to diet or sleep. While i do feel more sensitive to cold and tend to eat less, this could just as well be due to the loss in muscle mass, and it's hardly comparable to how i felt on my pre-peat diets.
