You talk a lot about the evils of grains. I follow your logic on why a grain free diet is best, and I have seen weight loss and just feel better overall since heeding your advice. But there is one thing (well, more than one) that I don’t understand but hear about often. Could you explain what gluten intolerance is and why you should avoid gluten?
Excellent question. Even though we’re seeing gluten-free labeling more and more, it’s not always clear why gluten can be problematic. Because of cross-contamination, it’s not always obvious whether a food contains gluten or not. Further, gluten intolerance symptoms can masquerade as other conditions. Let’s break it all down.
What is Gluten?
Gluten is a large, water-soluble protein that creates the elasticity in dough. It’s found in grains such as wheat, rye, barley, triticale, and oats. These days it’s also found in additives like thickeners and fillers used in everything from lunch meat to soup to candy. You can also find gluten in beers and vinegars that have been fermented from gluten-containing grains.
At this point, intermittent fasting isn’t a new concept, nor is it a difficult one. You take in all of your calories for the day within a limited window of time, and the rest of the day, you stick with water, maybe a cup of coffee, or tea in the morning if you feel so inclined. The idea is that giving your body a period of time “off” from digesting food allows your cells to heal and renew in other ways.
A Practice Born Because Calorie Restriction is Unpleasant
Intermittent fasting became popular because calorie restriction was found to contribute to healthy aging. A few mouse and worm studies seem to show that drastic reductions in food intake over a long period of time could prolong your life.
When describing someone that has successfully made the transition to a Primal or Keto way of eating I often refer to them as “fat-adapted” or as “fat-burning beasts”. But what exactly does it mean to be fat-adapted? How can you tell if you’re fat-adapted or still a sugar-burner?
As I’ve mentioned before, fat-adaptation is the normal, preferred metabolic state of the human animal. It’s nothing special. It’s just how we’re meant to fuel ourselves. That’s actually why we have all this fat on our bodies – turns out it’s a pretty reliable source of energy.
Here’s what you need to know about the benefits of becoming fat adapted, or keto adapted, and why it works with your biology.
The Primal Blueprint is generally considered a low-carb way of eating, especially in contrast to the Standard American Diet and the like. We’re not anti-carb. My Big-Ass Salad is a huge bowl of carbs from vegetables, after all. We’re selective about the sources of our carbs and generally mindful about how many we take in.
Given that, readers always want to know the “right” way to incorporate carbs. Which carb sources? How many? When? How often?
The Primal Blueprint Food Pyramid and Carb Curve provide answers to the first two questions. The latter two… well, those are more complicated.
I’ve written about these topics many times, but the questions keep on coming. Today I’m going to try to condense the main points into one post. I’ll touch on some issues you’ve raised in the comments of recent posts, too.
In truth, I keep getting questions because there are so few definitive answers about the optimal way to incorporate carbs in your diet. Underlying hormonal and metabolic health, activity level, and lifestyle variables to make it impossible to make across-the-board recommendations. Few studies address these issues, and those that do always use standard high-carb diets in their manipulations.
The best I can do is explain the logic behind different strategies and encourage you to experiment. As with so many things, it might take time to discover which strategies work best for you.

Even after publishing several books and hundreds of articles that draw upon the science of ketosis and low-carb living, I keep researching, thinking, revisiting, and discussing the underpinnings of ketosis. My writing partner, Brad Kearns, and I maintain a running dialogue on all things keto. The latest conversation revolved around two very common questions or “problems” that keep coming up in the ketogenic community: why am I getting low ketone readings?
It’s a fair question. Why do some people on a keto diet register high ketones while others eating the same way register low numbers?
I won’t offer definitive answers fit to etch into stone. I will offer my exploration of the research, some educated speculation, and actionable advice you can ruminate on. And by all means get back to me with your take on the questions and my explorations, please. Dialogue is essential to understanding.
A little planning and motivation will help you start a low-carb, keto, or Primal lifestyle, and under normal circumstances, keeping your carbs on the low side is easy. But let’s not create the illusion that it is easy all the time. From time to time, you may get stressed and eat mindlessly. Or, your aunt drops off her blue-ribbon cake that you’ve loved since you were in preschool, and you give in, just this once. Or, you had a jam-packed day and all you can muster to make for dinner is that package of gluten-free noodles in the back of your pantry. The next thing you know, you’ve eaten enough carbs for a week, and you wonder how you’ll get back into ketosis after a carb binge.
The short answer is, yes you will recover from a carb binge. Yes, you will get back into ketosis. As far as how long it will take to get back into ketosis – that depends on numerous factors, that we’ll dive into here. The important thing to remember is, you did not obliterate your goals with one misstep. Especially after you’ve spent some amount of time in ketosis, your body will allow for fluctuations in carb consumption here and there. That’s called metabolic flexibility, which we’ll go into shortly.
