Diet & Nutrition

This morning I shared how I’ve changed my approach to stress over the last couple of decades. For me, this meant first addressing the toll of my training. It’s how the Primal Blueprint, in fact, was born. In today’s feature and in this video (with my long-time friend and co-author, Brad Kearns), I talked about...

For today’s edition of Dear Mark, I’m answering several questions drawn from the comment board of last week’s post on fasting vs carb restriction. First, how do I square my recommendations with the successful reports of potato dieters losing weight on a high-carb tuber diet? Second, is Leangains optimal for mass gain? Third, how do...

Some rend your colonic lining to stimulate lubrication. Some turn into gelatinous slurries. But we can’t talk about fiber without understanding that the word...

For today’s edition of Dear Mark, I’m answering a few questions and comments from last week’s post on the carnivore diet. First, Dawn gives us the unfortunate but necessary information that it’s not just the lone star tick who causes red meat allergy. Great. Second, what are 7-Day Adventists so healthy? Is it all because...
