this is an interesting study to see. it’s a survey of mortality among japanese men and women and how their diets correlate with causes of death

personally, i’m not sure i find this a compelling argument against keto for men. their finding is increased mortality if their carbohydrate intake is <40% of their total energy expenditure. 40% is a pretty high bar for keto, where you’re looking to be at 5% at most (at most, 20g of carbs a day = 80 calories; 2000/80 comes out to be about 4%)

so probably, a lot of these people aren’t in keto, which i would consider a clinically relevant distinction (we don’t know for sure, since the nuances of the population’s eating habits weren’t published)

second, i don’t know that i would want to try keto in japan? like, i don’t know what their fat sources are, but… if i ate enough fish to sustain myself on keto, i’d get fucked up by mercury. and like… idk how much better it is? but a lot of my food comes from beef and dairy, which i don’t think are as commonplace there (i know it’s bad for the environment. i know. i know. i don’t want to starve though. i’m sorry)

i’m not that educated on how food looks in japan. but it strikes me as very keto unfriendly. depending, this might be a huge factor, or a minor one, but it’s hard to say without clarification

anyways, it’s an interesting post from a transmasc point of view. i originally fled carbs while running on estrogen. i feel like i tolerate them better (not well, per se) on testosterone. there’s a definite challenge on keto to eat enough calories on testosterone, especially now that i work out and i’m trying to build a considerable amount of muscle

but at the end of the day, i still feel better on keto, and now that i’ve figured out how to reliably provide like 3k calories in fat, i’m doing pretty well
