本周的《经济学人》的付费科技播客Babbage：大众对新陈代谢的普遍认知错在哪里？What people get wrong about metabolism —an interview with Herman Pontzer

#微博声浪计划##听见微博#

Do you run, cycle or swim to lose weight? Herman Pontzer, an evolutionary anthropologist who specialises in understanding how humans use energy, thinks you’re probably wasting your time. His idea of the “exercise paradox” suggests that the amount of energy people use in a day is constrained (by evolution) and that exercising more doesn’t end up burning more calories. Figuring out why our bodies work like this is part of Prof Pontzer’s bigger project to map out and better understand how evolution has shaped variations in human biology. http://t.cn/A6dWAmaf
