Been keeping a food diary for several months now. I did have to spend a bit of time at the beginning working out the calorie content of the food I eat. But after that it's mostly just copy + paste - turned out I was far more of a creature of habit than I thought.

If you want to derive any benefit from doing this you should really be trying to get your numbers correct from the start. I wouldn't leave that to a LLM.
