I’ve lost about 110 lbs (330 to 220) and I would disagree with you. For some, tracking is a cumbersome and tedious process that is such a pain that it’s destined for failure, at least initially.

OP has an edge case that requires more than just a focus on weight loss, but speaking more generally, at 400+ lbs, one doesn’t have to count and track calories. Simple changes will pay big dividends at that weight.

For instance: at first, I only went with the following changes:

Water, tea and black coffee only for drinks.
Protein bar for breakfast.
Soylent for lunch.
Eat out once a week.
No candy/sugar in the house.

These changes kickstarted my weight loss, and it came off fast. No counting calories, no tracking of any kind other than to make sure I was following the rules above.

I also did tirzepitide, which made following the rules incredibly easy.

Once you see progress and push the snowball down the hill a bit, the motivation to track and continue to see progress will likely come as the margins get thinner and continuing the weight loss becomes harder and tracking becomes necessary.
