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.
One of the more common questions we get in the Keto Reset Facebook community is, “How do I break through a weight-loss plateau?”
Stalls are frustrating. You’re cruising along on your Primal or Primal + keto diet, and then wham—you hit a wall. It’s all a totally normal and expected part of the weight loss process. Weight loss is never linear. There are always downs, ups, and flat spots.
In fact, if you’ve been losing weight for a while, and then you stall out for a week or two, I wouldn’t even consider that a plateau necessarily. Your body might keep losing weight on its own if you give it time and don’t stress about it. Still, I get it, you’re eager to kick-start the weight loss again.
It seems every “keto for women” forum abounds with stories about menstrual cycles gone wild in the first few months of keto. Irregular cycles, breakthrough bleeding, and periods lasting much longer than normal are common complaints. Sometimes these stories are cited as evidence that keto isn’t good for women, at least not premenopausal women, and that we need carbs for healthy hormones. Yet, many women don’t notice any changes in their menstrual cycles at all, while others report improvement in PMS symptoms and cycle regularity from the get-go.
What gives? Why do some women’s cycles apparently become wacky when they start keto, while others feel like keto is the key to period bliss? Can keto “mess up” the menstrual cycle?
While some keto or low-carb proponents claim fiber is useless at best and actively harmful at worst, I come down on the side that says fiber is probably helpful for most people. Some folks have persistently better responses to low- or no-fiber keto diets, and I won’t argue with that—I’ve seen it happen and I’ve read the studies where de-emphasizing fiber can actually improve constipation, for example.
I’ll just say that I have an opposite reaction, and, most importantly, I love eating a variety of plant foods that also happen to contain a ton of great nutrients in addition to fiber.
