Power analyses indicated that sample sizes were sufficient to detect a 4.2% difference in mean TEE (Hadza vs. Western, α = 0.05) in comparisons among women (power 97%) and 7.6% difference among men (power 93%).
So the Hanza people used more energy than westerners but I guess if you can just say 7.6% more energy is not significant then I guess it isn’t.
The paper you linked is literally saying the people that move more burn more calories.
I setup moonlight+sunshine, I don’t even remember anything about the setup because it was straight forward and worked without any tinkering. I even used a raspberry pi 4 as a client and it felt fine. I say just go for it, you’ll be up and running in just a few minutes and you lose nothing if it doesn’t meet your needs.
