Dear Mark: Is a High Protein Diet Really As Bad for You As Smoking?

It’s about that time, boys and girls. A new “protein kills” study has arrived to throw you into the pit of existential angst and self-doubt you recently managed to crawl out of from the last one. As you may know, I’ve just spent a week in Tulum, Mexico for PrimalCon (which was amazing, by the […]

For today’s edition of Dear Mark, we’ve got a four-parter. First, I discuss some alternatives to traditional outdoor sprinting for people in cold weather.
