Paleo and CrossFit… Can They Coexist?

Paleo and CrossFit… Can They Coexist?

CrossFit and paleo, two concepts that have grown side by side for the past fifteen years. Two market driven movements that promote health, minimalism, community, and two movements that are as controversial as they effective.

Having high stakes in both of these (I coach crossfit and use a paleo template in my nutrition coaching), I have seen first hand just how effective, and also how damaging these approaches can be.

First, we should look at both movements in their rawest form.

CrossFit: A method of exercise that practices functional movement at high intensity.

Paleo: A way of eating that promotes eating fruits, vegetables, meats, fish, nuts and seeds. In other words, eating as minimally processed foods as possible.

USUALLY, a standard paleo diet will be slimmer on the carbs and larger on the protein. Now, this doesn’t mean you can’t consciously smash your sweet potato and go “high carb paleo,” but most of us who go paleo will be leaning to the lower side of carb consumption (<150g per day) – that’s about 3 sweet potatoes.

Now, questions of doing paleo and crossfit; “is it optimal? Will it help me lose weight? Will it help me gain muscle? Will it save my life?” The answers to these are like so many in nutrition… “it depends.”

So it’s hard to give a definitive answer as to whether it’s right for you, but in an effort to reach a conclusion, I’ll give you three real life examples of people I’ve come across and you can make up your mind where you sit from there.

  1. “The Athlete.”

This girl is training 2 hours per day, 5+ times per week. She lifts heavy, goes fast, and is completely dedicated to making the sport. Her goals are to to put on muscle to lift heavy, but not too much that it interrupts her conditioning.

 

2. ‘The Superdad.’

He’s recently taken up crossfit and trains 3 times per week. He has a busy schedule with two kids and a full time job, but fitness still holds an important part in his life. His goals are to lose weight and stay strong to keep up with his kids.

 

3. ‘The Office Jockey.’

This guy has recently taken up crossfit as the doctor suggested it. He’s overweight, has insulin resistance, and has high blood pressure. This guy is also extremely sedentary, and hasn’t had regular movement or sunlight since school. He’s started training 2 times per week and goals are to lose weight, feel more energy and build some muscle mass.

 

Now, the verdicts.

1. Should the “Athlete” eat paleo?

No! Why? Let’s look at her schedule… She’s training around 2 hours a day and spends the rest of the time recovering and thinking about training… Glamorous?! She’s using her anaerobic system consistently, and this system runs on glucose (carbs), not fat or ketones. Fran doesn’t run well on fat.

Carbs such as potato, sweet potato, beets, pumpkin, as well as non – paleo foods in rice, quinoa, oats (gasp) and other whole grains should be a staple for these guys, whereas our first two friends should be more diligent with them. Protein should obviously be a priority as maintaining muscle mass is important, and fat should be adequate.

Nutrient timing is also important. Post workout carbs will help funnelling nutrients to the muscles so adding some dextrose to her Barefoot Health protein shake would be helpful.

But won’t all those carbs store as bodyfat? Carbs, insulin, fat storage right?! Not quite. When we’re doing this type of anaerobic training, we mostly store these carbs as glycogen, not body fat. A whole different set of rules applies to our “Superdad” or “Office Jockey”, so don’t do a Michael Phelps and eat 12 wheat bix for breakfast just yet.

 

2. Should the “Superdad” eat paleo?

Yes! Greg Glassman’s initial mantra of “eat meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar” is a perfect fit for this guy. In addition to this, a little tinkering with carb timing and quantity is required here to make sure he’s keeping the belly fat off.  He should ensure he’s getting carbs post workout, and enough to support his activity – around 150g per day seems to be a good area to stick to. His plan also has some wiggle room… Since he’s pretty active, sleeps well, and has good community, sticking to a plan of 80/20 paleo/non paleo will work well and be sustainable and give enough room for a glass of wine over his grass – fed steak.

 

3. Should the ‘Office Jockey’ eat paleo?

Yes! Absolutely. It might just save his life. Most carbohydrates will not be friends with this man, and his diet should be centred around healthy fats, protein and veggies.  Why? Well he’s one of 2 million Australians with pre diabetes, and a continuation of his current lifestyle will land him will land him in a very dangerous state. Having extremely low glucose tolerance means eating things like cereals and wholegrain bread is lethal, as it’s jacking up our blood sugar, and we don’t have the necessary insulin function to maintain homeostasis. (cereal and wholegrain bread are both recommended from our chief authority on diabetes – shocked face).

Now, should this fella get into the gym, and I hope he would, he might want to add some post workout carbs in the form of sweet potato or pumpkin, but I’d recommend going between 50-100g of carbs in the short term to restore some baseline of health.

 

Wrapping Up

So the point here is to accept that we’re all the same but different animals with different nutrition requirements for optimal health. At a baseline we can all agree that a diet with heaps of veggies, enough protein and healthy fats is good for all. But digging deeper, we need to consider our genetics, activity level, activity type, hormonal profile and GI status when deciding what the optimal diet is.
