Episode 434: Fit But Unhealthy?

For this episode, I share some thoughts on the topic of "fit but unhealthy." Recently, pro triathlete Lionel Sanders shared some details about his health concerns. This came as a surprise to some as he is visually very healthy and performed at a very high level. Some have hypothesized it is due to his hyper carb fueling strategy. Others have suggested endurance training to the degree taken by professional athletes is unhealthy.
