I'd typically take all this advice with the understanding that they're all selling things in some way, may have a radical leaning for engagement and would calibrate my behaviors accordingly - but things being as you've described, i'd say really internalize it.

Ken Berry is very much an advocate for full carnivore, even if you can only afford hot dogs and says that milk is useless for anyone beyond breast feeding age. Of course grass fed/finished meat, ethically raised animals is the best way to go.

Snacking on bacon, pork rinds. High fat content will help stave off any cravings hunger and sugar cravings.
I do one meal a day, assisted by a bulletproof type of coffee: grass fed butter + mct oil, I do grass fed ghee + coconut oil.

You have a tough path ahead, but its a path nonetheless.  

 Going in and out of ketosis also  sucks, so really try to stick with it and avoid the keto flu as much as possible 

 Keto-chow a mineral and salt suppliment helps with getting what you need because you'll be losing a lot of liquid and minerals in that transition phase. 

 yeah, speaking of which, fasting is starting to come up in my mind a lot about something that would help

this peripheral neuropathy is driving me absolutely nuts in recent weeks, today, my right hand is totally prickly and weird, itchy for no reason... and i've had a constant problem with what i now think is dermatitis herpetoformis, which is a reaction to gluten proteins! something i've had problems with since my mid 20s, extremely irritating, get it on my hands, elbows, knees, and very rarely feet

feeling pretty dark mood today with all this on my mind and how i'm feeling physically 

 I've really dropped off this past month - sugary alcohol, less strict with carbs and multiple meals, might be noticing early symptoms myself so I'm going back. 

Two things I noticed with the ketovore&one meal a day brings an  eternal but subtle tunnel vision through out the day from the fast and the diet change definitely with energy levels + skin flare ups way less and more managable.

Also just remembered Paul Saladino, started 100% carnivore and shifted a little for a more wholistic evolutionary diet, but still primarily meat based.

think in general they'd agree that short term ketosis is helpful. At the minimum you've done an elimination diet and can introduce things after

Rooting for you. ✌️
