This is a higher level of physical activity in minutes per day spent walking etc. The paper gives average mass and lean mass for Hadza, males come in at 50.4 kg total, 43.7 lean. So that leaves something below 13 percent for body fat.

Also fairly short people. How many parents are willing to "stunt" their childrens growth? I quotations because--is there really a problem with these people's height, or has our growth been over-stimulated in some way? Not just talking the Hadza, this is a repeating theme, a lot of these modern hunter gatherer groups are short. I don't know if it's diet related or just genetic (although if it was genetic, I'd wonder if there's some advantage then to them being short)?
