Historically, when did the main meal occur in many societies due to dictated labor patterns?

Answer

Later in the day, midday or evening

The emphasis on a large, structured breakfast appears to be a relatively modern construct, often aligning with industrialized work schedules. Historically, in many societies, the primary, substantial meal of the day was timed to occur later. This timing was dictated by the need for substantial fuel only after the morning's physical labor had already been underway. Therefore, the largest caloric intake was typically reserved for midday or evening, reflecting the energy demands of physical work patterns that differed significantly from modern routines.
