Mine is mixed. I did simplify things when I skipped vegs and added meat but I do love reproducing textures as I love great textures. I am very good at making quick protein rich super crunchy things lately.
I think it’s normal people don’t focus on recipes so much after a while (I only do that to some extent because I still introduce new ingredients and figure out good ways to makemore enjoyable, more protein rich - less fatty - food AND because making new recipes is my hobby, I miss it if I don’t do it for a while) as they figure out how they should eat. They either lose the desire for the old things or make great replacements or maybe something else happens (carnivore made me quite lazy so I don’t complicate things too much. never was into complex recipes but now, if I can just eat some simple carni food with joy, I really don’t want to bother with something else unless I really want something special). And they focus on other things while eating the simple food that works so well.
I don’t do the bloodwork and supplements route personally, I just listen to my body (or something not but if it’s loud enough, I do as I want to feel great).
I started with higher-carb vegetarian keto (40g net carbs, probably up to 100g total) where I half-lived on sweets out of necessity (everything was carbier than my sweets. and I was an experienced low-carber… but I loved vegs). It wasn’t simple at all. I am not able to eat very simple but still, there are levels and some of my mostly carnivore days are pretty simple. it’s significantly more difficult without meat especially with vegs, I had to track all the time.
Fasting is harder as I lower carbs but IF is how I live so that changed little. I do try to go for OMAD, it started to get easier physically and it has its benefits but it’s not always viable.
I used to do so many experiments to figure out how I can minimize my energy, fat and protein intake (as I tend to overeat them all. sometimes carbs too but I can’t accidentally overeat carbs while I can it with both fat and protein. my normal items are quite low-carb to begin with or used in tiny amounts) but I got enough data (unless I drastically change something again) to have some good idea about how to eat. So I mostly just try to use my knowledge about myself now.
Tracking is tiresome and at this point, borderline useless (I got my data already) so I barely ever do that.
I am at the point where I know what to do and should try harder to do it really well.
