this is fascinating, I couldn't have guessed this.

This is in the same category as: sit on the couch watching TV and you're spending almost the same amount of calories as a walking person.

Maybe it also matters how you spend those calories. Fasting helps a lot, westerners don't fast. I assume hunter tribes fast more and also have lots of short bursts of energy.

“ sit on the couch watching TV and you're spending almost the same amount of calories as a walking person.”

Some quick googling tells me that walking burns 4x as many calories as sitting. Or maybe I missed your point and you were just claiming that the stated fact is as surprising as this fact would have been had it been true?

I am off, you are right. I remembered something vague but it must have been: watching tv while eating (140 calories an hour) vs slow walking at 220 calories an hour.
