I do nothing to maintain, it happens anyway (but I am still fat. I hope it will be the same later too). Losing fat is the nearly impossible thing to me, it took a lot of time just to get the method for it and following it is another matter… I tracked to figure out how to get satiated while not eating a ton, which items to minimize or avoid (except on OMAD where the goal is eating as much as I can for my meals, it’s not trivial for me on carnivore. only on higher-carb), which items gives me the highest satiation… But I learned about good timing and other things as well. So I got info from tracking, it surely never helped me directly with fat-loss…
Planning can be useful too (even if I don’t stick to the plan, just partially).
Tracking for a little while in the beginning may be especially useful but not everyone needs that. If you don’t, that’s great, I would drop it if I could, tracking is a chore… But gives me fun numbers sometimes And it helps with my decision making but that’s individual too. I can avoid late eating if I eat right during the day. My body has some quite fixed rules where tracking can help.
If one eats various carby items on keto, the carb limit may be too easily breached without tracking. I had to track my carbs on my original keto. If one barely eat carbs, have a big carb limit or don’t care so much about being in ketosis as much as possible, tracking may be never necessary. My vegetarian keto was impossible to do without tracking. I don’t need to track carbs on carnivore or even just somewhere close to it, I track for other reasons.
Tracking is most important when I experiment and try to figure out something and it’s related to my macros.
But I am always curious about how much meat and eggs I eat, how low I keep my dairy consumption… I had a time when I had a spreadsheet with many rows and I had average, minimum, maximum numbers… I liked to get numbers but not the work so I dropped it. I do it again for November but I will eat simpler. But this month I will track how much I eat from different animals, it will be interesting! (Even though I know it probably will be 90% pork…)
So it’s kind of a hobby driven by curiosity… Even if it’s a chore, I love cooking too and still can find it tiresome sometimes.
So… You should do what you need or want to do. If you don’t know if you need tracking, don’t do it yet. Give it a chance that you get success without bothering with it.
Maybe tracking a typical day occasionally give you some insight though… But maybe it’s not important for you.
