The struggle (with keto) is real. I love and hate that way of eating. About 30 years ago I did a strict Atkins Diet (long before "low carb" was popular) and I never felt better. I did it for 9 months, and then started having a strange medical symptom (skin related) that none of the doctors could figure out, and since no one knew much about low carb back then, they all chalked it up to my way of eating, so I gave it up and started eating like everyone else.
Then a few years ago when I remembered how great I felt doing low carb, I learned all I could about the keto way of eating and followed it strictly. I lost weight and usually felt great, but there were days when I would feel pretty bad (either mentally, physically, or both) and I would wonder if it was diet-related. If I posted on the keto forum, of course they would insist it was NOT caused by the diet, or they would tell me what additional supplements and vitamins and minerals I needed to add to my diet. I never could figure out if any of it were true, and you really shouldn't be haphazardly throwing new vitamins and supplements at your body without knowing for sure your body NEEDS them, so there were side affects from those, interactions with my medications, etc. In the end, I went with "moderation is the key" and stopped doing strict keto and added back in some carbs. I still try to limit them as much as possible, but I'm definitely not staying under 50 grams a day, either.
It could very well be that the keto way of eating IS a good thing for some people, but that it takes our bodies a long time to adjust to it so who knows if your symptoms are a result or not. Or if they would go away if you stuck with it until your body chemistry regulated. There are just too many variables involved when eating strict keto, and not enough known about it. My doctor was strongly against it, BUT my blood test numbers all looked good from eating that way, so who knows?
