Yeah, it’s very personal, and there’s no rule that say you should eat later in the day.
Personally, it’s way, way easier for me to eat in the afternoon - I’ve never been a breakfast person, and I have trouble falling asleep on an empty stomach. I also have this thing where it’s hard for me to stop eating once I’ve started, so eating in the morning means fighting against myself for the rest of the day!
So yeah, people shouldn’t be stuck on a specific window and do what works best for them - physically, psychologically, and according to their life schedule. It won’t change the results.
