I mean, sure. But doing it poorly always comes before doing it well. So, the best advice for people that aren't aware of how much they eat is fine to start at anything basic. Probably the more basic the better. Though, as you note, that will be different for different people.

That last is notable. I agree that personal signals are very different between people. But so is basic capability to track things.

What is truly obnoxious here, is that what works for you will also not be static. Expect that what worked for you now will someday not work.
