In the Zeit Wissen podcast, Max Rauner investigated the amount of energy the body actually requires for the heart, lungs, and brain, as well as for digestion and muscles. For this study, researchers assessed the metabolism of a representative sample of the population, top athletes, expectant mothers, and the reporter for Zeit Wissen.
Germany-based Zeit Wissen is a bimonthly journal of popular science and is created by the weekly German newspaper Die Zeit. The German expression “Zeit Wissen,” which means “Time-Knowledge” literally, alludes to the current nature of the magazine and covers the latest advancements of a wide range of subjects, including technology, science, history, fashion, contemporary lifestyles, avant-garde art, photography, health, and even gastronomy.
