How to Lose Fat with Primal.

Note. Many of you have written to me wondering about my newfound obsession with CrossFit. I'm responding to a steady stream of requests from crossfitters who want to do primal

but have been led to believe that the two are incompatible.

Even if you have no interest in CrossFit, understand that much of the

advice contained in this series also applies to people following a different training

path. As much as Crossfitters claim to concern themselves primarily with increasing physical

performance and work capacity across broad modal domains, they also want to lose body fat. There's nothing wrong

or superficial about that, mind you. Excess body fat is unnecessary, and depending on the quantity

and location, dangerous to your long-term health. It also impedes performance, acting as a dead

weight. We have every reason to want to lose body fat. Crossfit is well known for

leaning people out, but there's also a small but significant portion of people who struggled to

lose body fat despite, or perhaps because of, hitting the box religiously and doing all the workouts.

This post is for them. Many people ask, I'm crossfitting. Should I go low carb or high

carb to lose body fat? My answer is yes. You heard me right. You should do both. As I explained in a

previous post, crossfitters require carbs. How many depends on their level of fat adaptation, the intensity with

which they train, the training volume they accrue, and other factors. But the fact remains that

CrossFit workouts are very glycogen demanding. If you want to maintain an increased performance,

you need to refuel that glycogen, and starchy carbohydrates are the best

way to do it. Revisit the carbs-slash-cross-fit post to get some ideas on good primal sources
