Recent studies estimate that the Hadza, a hunter-gatherer tribe in Tanzania, consume between 80 and 150 grams of fiber per day, a dramatically higher intake compared to the average Western diet. This extraordinary fiber consumption has been a subject of great interest in understanding ancestral health and its impact on the human microbiome.

Studies of modern hunter-gatherers, like the Hadza of Tanzania, show ancient energy expenditure could range from 1,900 to over 8,000 calories per day, depending on factors like age, gender, and environment, revealing how many calories did ancient humans eat per day was highly variable.

In a groundbreaking 2012 study, researchers used advanced techniques to measure the energy expenditure of the Hadza, a traditional hunter-gatherer group in Tanzania. The findings revealed a counterintuitive truth: Hadza adults burn a similar number of calories per day as average Westerners. This challenges the long-held assumption that their active lifestyle results in a higher total daily energy expenditure, and provides critical insights into **how many calories do the Hadza eat** in their unique nutritional environment.

Despite leading highly active lives, research suggests that contemporary hunter-gatherer populations, like the Hadza, do not burn significantly more calories each day than average adults in industrialized societies. This surprising finding sheds new light on the complex question of **how many calories did ancient people eat a day?**
