Why Did Ancient Humans Eat 3 Meals a Day?

Why do humans eat three meals a day? Breakfast, lunch, and dinner feel so natural that you might assume humans have eaten this way for thousands of years. But they haven’t. For most of human existence, your ancestors didn’t wake up for breakfast at 8, stop for lunch at noon, and sit down for dinner at 6. Hunter-gatherers ate around opportunity, season, travel, and successful foraging. Farming made food more predictable. Ancient cities turned meals into social rituals. Religion changed when people were allowed to eat. And eventually, factories and clocks helped turn three meals into the daily schedule millions of us follow today. In this video, we explore the surprising history of breakfast, lunch, and dinner, from prehistoric hunter-gatherers to Ancient Egypt, Ancient Rome, medieval Europe, and the Industrial Revolution. You’ll discover how modern Hadza hunter-gatherer research gives us clues about flexible foraging and eating, including a 2016 study that followed Hadza men for 921 hours and found substantial food consumption away from camp.
