Originally it was fat-loss. It never happened but I saw this is a nice direction 
In the very beginning when I went to low-carb, I wanted to lose fat (and I did then) BUT if I already started to focus on my woe more and read various things about styles that seemed okay for me, I realized it’s time to start my big journey towards my ideal, sweet spot woe! I keep improving in average, I have worse days but no way I could go backwards longer term.
So it’s mostly health and well-being but losing fat is kinda important too, I just never was in a big hurry. I never was obese, maybe borderline and I did want to lose fat more then. And now when I kinda had enough of my 8 years stall (and sometimes gain but I am bad at gaining just like I am bad at losing. I am awesome at stalling while overweight).
My first priority is still health and I have some tiny hope than maybe one day I will have some normal amount of energy instead of my usual low and rare extreme low. I already had better moments, maybe…
And well, fun and joy, always. I am a hedonist so that’s very, very important. I want to be a near perfect hedonist, eating whatever gives me the biggest joy. And food that my body doesn’t like clearly not like that. But as my best food is the tastiest at the same time, I only need to train myself out of wanting the tasty, not good food It’s not as easy or hard as it may seem, it’s complicated. But practice makes better 
I can relate to what @Shortstuff wrote too. I never did food things out of motivation, actually. I never could sacrifice things as I don’t do something out of motivation. I do it out of joy or curiosity or yep, because it’s how I live and I can’t just change it (apart from having off days here and there). I don’t keep myself on keto or on carnivore-ish, I just… Can’t eat differently, only temporarily and that feels off and I inevitably come back to feel right.
Even in the beginning, it was okay while lasted, never had to find some motivation to do it as it wasn’t bad and wasn’t hard apart from missing my vegs too much sometimes.
Oh and I think it’s motivation that I am better mentally on extreme low-carb. It’s only regarding food, I don’t feel different otherwise. Carbs mess with my mind somehow and I am hungrier, I want sweets etc. (And if I eat sweets, nothing gets better. Not hedonistic at all 
) Compulsive eating emerges, I lose my perfect satiation and satisfaction… Nope.
But I don’t get much from these negative carby side effect on OMAD so that’s a good way to mitigate the problems quite seriously. So I have anti-motivation to stay on track all the time. Still, I know it’s important for my health to stay very low-carb most of the time. And I would do even sacrifices for health, I just don’t need to do it (or I don’t know about that), lucky.
I really, really like my food. I can’t always eat enough eggs and meat and fat, it would be very bad to lower their amount due to stupid carbs! Or not lowering anything just starting to overeat massively again… I hate that.
So I have motivation but I don’t really have urges to raise carbs so motivation or not, I do keto most of the time anyway as it’s the easiest and best.
I wrote joy and fun. It’s not just the joy of eating. I am curious and love experiments They help a lot. (But everything is an experiment. Eating a ton of sugar is an accidental experiment to me… But all my planned ones are strict It’s fun! Of course I choose my rules well as I don’t resist temptation. But well planned experiments help with avoiding temptation.)
Maybe it was too complicated but me and food is complicated from some viewpoint. From others it’s simple. I just eat whatever I consider right or whatever I fancy or whatever I am compelled to (the latter is always stronger). Okay, it’s not simple.
This forum kinda motivates me too…? Whenever I read about people eating right and enjoying it, I feel more tempted to do the same. I follow my own desires but they aren’t completely unrelated to everything that isn’t me. So the forum helps a bit. Maybe motivation isn’t the right word for this.
