We’ve got a three parter for today’s edition of Dear Mark. First up is a question about gallbladders and a Primal way of eating. Or, more specifically, the lack of a gallbladder, and how one can make Primal work without one. Just because your ability to digest fat is a bit impaired doesn’t mean you can’t eat this way. Next, I explore what CrossFit really thinks (or doesn’t) about walking, hiking, and other sorts of frequent slow moving. After all the anaerobic WODs, is there room for a relaxing walk with your significant other? And finally, I discuss the usefulness – or not – of Gluten Cutter and other gluten digestive aids. These products claim to help even sensitive people digest and detoxify gluten safely, but are they legit?
