One of my parents has become dangerously underweight. We’re working with doctors on it. But one thing that they agreed would help would just be calorie counting. (They don’t realize how little they’re eating.)

I’m getting my parents Apple Watches (ultras if not too heavy; for battery life). [having recently spent time in hospital trying to untangle events regular vitals tracking sounds very smart]

Question:
What are good ways to track food / calorie intake on watch?

Natively. 3rd party. Whatever.

Huge bonus if it can be done with voice control.

Thank you all for any help 🙏
