Brandon Carter has built a career out of testing fitness and nutrition ideas on himself before he ever recommends them to anyone else. So when Brandon Carter sat down with Sean Kelly on the Digital Social Hour, the conversation dug straight into the science and the personal experience behind some of his most talked-about experiments.
The energy stays candid throughout — a fitness entrepreneur walking through what actually happened in his body during a year of hormone therapy and months of strict ketosis, without the usual marketing gloss.
