This is a great read - a mix of human interest story and science. This goes into nutrition, physiology, biology, and has a commentary on how a lot of the knowledge here is still evolving. I learnt a lot from this one.

“PONTZER GOT A LESSON in the value of food sharing in 2010, when he traveled to Tanzania to study the energy budgets of the Hadza hunter-gatherers. One of the first things he noticed was how often the Hadza used the word “za,” which means “to give.” It’s the magic word all Hadza learn as children to get someone to share berries, honey, or other foods with them. Such sharing helps all the Hadza be active: As they hunt and forage, Hadza women walk about 8 kilometers daily; men, 14 kilometers—more than a typical American walks in 1 week.

To learn about their energy expenditure, Pontzer asked the Hadza whether they’d drink his tasteless water cocktail and give urine samples. They agreed. He almost couldn’t get funding for the study, because other researchers assumed the answer was obvious. “Everyone knew the Hadza had exceptionally high energy expenditures because they were so physically active,” he recalls. “Except they didn’t.””
