Why Do We Think We Need Three Meals a Day?

Breakfast, lunch, and dinner feel like a natural timetable, but people have not always eaten by that clock. Work hours, later dinners, factory bells, schools, transport, and city lunch options all helped shape the routine. We trace how morning, midday, and evening meals became a familiar social pattern, then ask what that pattern means for us now. Three meals work well for many people, but history and nutrition do not make them a universal rule.
