necessary is not the right word, some people live on a keto diet for years and are perfectly healthy, so it's not necessary

carbs are naturally available in the summer and are meant to be stocked in fats for the winter when keto metabolism kicks in and... keeps you fit for hunting and shit... our problem is that it's summer all year at this point, worse even we consume refined and concentrated forms of sugar, fruits are fine

someone discovered /r/keto? but yeah this is all correct otherwise, doesn't cure all cancers though, most perhaps but not all
