I eat like a caveman.
Well, ok, not exactly like a caveman. We don’t know with 100% certainty how pre-agricultural man ate and I admit to enjoying the occasional bottle of wine, bar of chocolate or aged cheese – all of which I can pretty comfortably say wouldn’t have been easily available 20,000 years ago. Let’s not get too bogged down in particulars here though, compared to the vast majority of my modern man compatriots I eat like a caveman.
So why do I eat like a caveman and not the way everyone else eats? Let’s take a look at two average specimens of good ol’ Homo Sapiens and see if we can’t solve this riddle.
- Caveman – Our paleolithic specimen is tall, even by today’s standards. He’s what most people would probably call ‘ripped’ (think Olympic gymnast or sprinter) with a body used to running down animals twice his size for dinner and running from animals twice his size to not be dinner. He gets a good nap in everyday, and even has straight, cavity-free teeth.
- Businessman – Now our modern day speciman on the other hand, is several inches shorter than his ancestor. What he lacks in height, he makes up in girth as he’s currently 60 lbs. overweight. He gets winded if he takes the stairs at work, and needs several strong stimulants to make it to lunch which comes from a box or a drivethrough window. Oh, and he’s already losing his hair at 30.
So what happened? In a word, agriculture. Mankind had just spent around 100,000 years slowly adapting and evolving to live a hunter-gatherer lifestyle. 100 millenia’s worth of subtle, trial-and-error tweaks had made us pretty good at living in that environment.
Then, we had to go and mess things up.
Ok, so agriculture wasn’t all bad. We wouldn’t be here today without it. Agriculture provided a surplus of food, which let us settle down and invent the Internet. Eventually, anyway. The problem is, this all happened in the span of about 10,000 years. That may seem like a long time, but in evolutionary terms that is less than a blink of the eye.
It’s like waiting until you’re 95 years old and then deciding you want to be a professional linebacker – our bodies just couldn’t handle the sudden change. We had enough food to survive, but that food made us sicker, shorter and weaker than we had been a few thousand years previous.
The main culprit? Grains. We didn’t really eat grains before we domesticated them. They can be hard to find, they have to be processed to be consumable, and they have comparatively little to offer nutritionally.
Grains, unlike some other plants, don’t want us to eat them. They are full of two very nasty chemicals, lectins and gluten. Both of these cause systemic damage to the human body, causing inflammation, intestinal damage, allergic reactions and all sorts of other unpleasant things.
On top of this, grains consist almost entirely of carbohydrates. Extremely dense sources of carbohydrates are extremely diffcult to find when living as a hunter-gatherer and as a result, made up very little of our ancestors’ diet. Our bodies adapted to make the most of the carbohydrates that they could get.
The basic process is that carbs are turned into glucose which is then used for energy and to feed your brain and help some other body processess. The extra glucose is then stored as fat since, back then anyway, big doses of carbs were few and far-between and times of starvation were a real risk.
There’s more to the process involving Insulin and some other fascinating bits of body chemistry, but I’ll leave that for another time. The point is, too many carbs in our diet nowadays makes us fat. We don’t have to battle a horde of irate bees over their honey to get a sugar rush anymore, we just have to open a box of cookies or down a soft drink. That’s bad.
So how do we fix it? We eat like cavemen! Or at least as close to it as necessary to get the benefit of expressing our genetics in the way evolution shaped them to be expressed.
What do I eat?
- Meat – Sorry vegetarians, but this lifestyle probably isn;t going to work for you. I’m being all-inclusive with this category. Beef, pork, chicken, fish, eggs, & any other animal it is societally acceptable to consume. You want all your meat to be grass-fed, not grain-fed. It’s worth checking into, since eating a grain based diet is just as bad for the animals you eat as it is for you. You want your eggs to come from free-range chickens (Omega-3 enriched are a nice bonus) and your fish to be wild, not farmed.
- Vegetables – Go crazy. Eat as many different vegetables as you can handle but stay away from the extremely starchy vegetables whenever possible. This includes potatoes. Sorry. Also stay away from corn. Corn is a grain, not a vegetable, and is particularly bad for you, especially since it is in everything now.
- Fruits – This is the only place you should be getting your sugars from. I indulge in a bar of dark chocolate every once in a while too, but it is extremely rare. Too many fruits may hamper weight loss efforts a bit, but for overall health they’re great.
- Fats – Stick to good, naturally made fats. That means no to margarine, shortening, canola oil, vegetable oil and peanut oil. The why’s are somewhat complex, but you’re far better off sticking to olive oil, lard, butter, avocado oil & one of my personal favorites, coconut oil.
- Extras – Things like nuts and seeds can make a fantastic paleo appropriate snack, or a good way to bump calorie intake up a bit if you’re having trouble adjusting to the diet changes. Be careful though, nuts and seeds pack a lot of calories in a little package and shouldn’t be eaten in too large of amounts.
That’s it! That’s what I eat. Now on to what’s equally as important.
What do I not eat?
- Grains – This one should’ve been obvious. This also includes anything that has grains in it. That means no bread & no baked goods. It also means no corn and nothing with high fructose corn syrup in it (trust me, you won’t miss that).
- Refined Sugar – All the sugar in my diet comes from either fruit, honey or the previously mentioned occasional treat. No more soft drinks, no more sugar in your coffee and no more candy.
- Dairy – There’s a lot of arguments about this one. On one hand, our ancestors never would have drank milk past infancy, and certainly not that of another species. That being said, a lot of people can handle milk tolerably well, and butter – though our ancestors may not have had it – seems to not have any of the detriments of other dairy items. Personally, I avoid milk, eat lots of butter (from grass-fed cows), and enjoy a good aged cheese now and again.
This is the basic outline of what it means to eat like a caveman. I could explain all the health benefits, talk about all the people who have gotten into the best shape of their lives eating this way or share my own personal story, but who cares about all that? My advice, try it for 30 days. 30 days is nothing, and if you don’t feel like a whole new person you can always go right back to eating donuts and drinking soda.
