It's all downhill when you hit <insert 40 or 50> years old!" is one of the most heard phrases by not yet middle-aged lifters at family events. But is that true? In this episode we address "metabolic myths" related to energy expenditure changes over the lifespan, so-called "differences" between the sexes, and also cover some crazy realities like the true extent of individual differences in energy expenditure, and how things change (or don't change) during pregnancy. Make sure to tune in to this episode of Iron Culture so you can start more sentences with "umm actually…" at family gatherings.
