so lunch AND dinner or just early dinner? always feel like these hourly windows are underspecified since you can cram a ton of food in that time

If it's a 10 hour window presumably most people are eating multiple meals, but it's not really underspecified since you can eat whenever you want during that time.

There are other people doing 4 hour windows for IF in which case it's more like a single meal, but that's not what this study tested.

(This is just explaining the idea, not advocating IF)
