What factor does the table suggest imposes difficulty when labeling a post-noon meal as breakfast for someone on a standard schedule?

Answer

The social expectation of the time slot imposes a cognitive load

The insight derived from observing schedules like the 6:00 AM–10:00 AM window versus the 11:00 AM–1:00 PM window reveals a psychological barrier. Even when an individual wakes late (e.g., 11:00 AM) and eats at 1:00 PM, making that meal functionally their breakfast (the first meal after sleep), the deep-seated **social expectation** that breakfast belongs strictly in the morning creates a **cognitive load**. People mentally resist labeling a post-noon ingestion as 'breakfast' because it violates the learned cultural norm tied to the time slot. For those adhering to a standard rhythm, skipping the morning window often results in that meal slot being categorized as 'lunch' by default, even if the body has technically just broken its overnight fast.
