I didn't perceive it as negative.
I just wanted to say I've been there, down that thought-route but then I recalled that objectively I am having better nutrition now than ever in my adult life so that is not what worries me and that the only item I could wonder about is the effect of long term ketosis BUT the level is only mild and not extreme, Eskimos and all other populations living on a high proteic, low carb diet live with it all their lives and pregnant mothers experience it for 9 months at a time safely so realistically the probability that it will do damage to my health is less than the probability that sheer boredom will drive me to do damage to myself by absently knawing into my fist pretending it's bacon! -Dark humour but you get the gist-
