If you read any of those “10 Reasons Keto is the Worst” articles out there, the common anti-keto argument you’ll see is that it’s too hard. The premise: keto must be unsustainable because eating meat, eggs, avocados, veggies, nuts, coconut, etc. is just too arduous long term. I’m sure you can guess how I feel about that.
Nonetheless, when you switch from a SAD diet to Primal or Primal-keto it genuinely becomes harder to grab convenience foods. It’s not that you can’t. The selection of packaged foods being marketed to keto folks has exploded in the past year or so. Rather, your growing awareness of ingredient quality, coupled with a desire to control your food and nutrition, makes it feel harder… and probably less desirable.
For that reason, many people end up doing more cooking at home, which means more time devoted to grocery shopping and meal prep. This is good news. But once in a while, especially during busy weeks, it’s nice to give yourself a break and grab something easy. Plus, sometimes you find yourself stuck somewhere without a lot of food options. And then there’s the craving for foods you once loved and wish you could find keto-friendly versions of….
So, while I think that preparing your own food is a great ideal, I also want to cover keto where keto dieters actually live—in the (generally speaking) non-ideal world. I’ve always said, “Don’t let the perfect be the enemy of the good.” How can we apply that to keto convenience food?
My readers know I’ve always advocated for the 80/20 principle: aim for 100% compliance, but give yourself the freedom to respond to your circumstances and (occasionally) your desire for wisely-chosen indulgences. Primal and keto eating have to be enjoyable to be truly sustainable. If this means you sometimes incorporate convenience foods, so be it.
Convenient “Whole Foods”
Pre-made frozen hamburger patties and pre-cooked chicken skewers were in heavy rotation when my kids were deep in the school-sports-homework-friends circus. Rotisserie chickens are usually not the “cleanest” (look for “naked” organic options if you can), but they aren’t the worst thing in the store by far.
Bone broth is easy and economical to make, especially if you have a slow cooker or pressure cooker, but there are several companies now offering high-quality bone broth that I enjoy sipping on throughout the day.
While fresh is best when it comes to vegetables, I haven’t riced a head of raw cauliflower in ages now that frozen organic cauliflower rice is available in every market we frequent. Frozen veggies retain most of their nutrients. Pre-cut vegetable noodles are an easy time-saver.
With all these foods, you’ll definitely pay a premium over doing the work yourself. However, if you can afford them, and it buys you some time in your busy schedule, don’t let concerns over small nutritional trade-offs get in the way. Grab that rotisserie chicken and a bagged salad, or pre-made zucchini noodles and a jar of (extra virgin olive oil) pesto guilt-free.
Convenient “Packaged Foods”
Basically I’m talking here about eating food with labels, foods specifically meant to make your life easier or to quell a craving for a SAD food.
Spoiler alert: I’m not going to give you a straight up NO to any of these. If you want to eat them, ingredients should be your primary consideration. There are plenty of foods being marketed as keto and low-carb that are not at all Primally aligned. Carb count doesn’t matter to me—if a product contains hydrolyzed wheat gluten and canola oil, I’m out. Yes, some of these you can make yourself—and I’ll provide some recipes for alternative options within each category even though I know this misses the point of convenience foods.
Breakfast is such a sticking point for people when they go Primal or keto. It’s the area in which folks seem to feel the most “deprived.” One of the most common questions we get in our Facebook groups is, “What do I eat for breakfast if I’m sick of eggs?” It’s no surprise then that you can now buy keto pancake and waffle mix, and grain-free “oatmeal” and granola. There are even keto cereals creating quite a buzz in the marketplace. Honestly, I don’t have a problem with these products occasionally. While you can find a thousand ways to do keto-friendly breakfasts that offer more nutrition, I know Americans have a particularly nostalgic attachment to our conventional breakfast foods. If eating keto cereal once in a while is the thing that makes the rest of your diet smooth sailing, go for it.
I’m not a neutral bystander here—Primal Kitchen makes a keto-friendly protein bar. Primal Kitchen or not, however, I’m not opposed to bars as a snack, as a quick pre- or post-workout bite, or as a lunchbox treat. Personally, I like to take a bar during a long paddle or bike ride. This is a category, though, where you really want to check labels. A lot of manufacturers fill their bars with fiber (to drive down the net carbs) and sweeteners, which some folks are sensitive to.
Make-it-yourself alternative: Vanilla Coconut Collagen Bites
Meal Replacement Shakes and Powders
Again, I have skin in the game here, since Primal Fuel was one of my flagship products. I still love and use it regularly, so obviously I have no problem with whey protein shakes. At the same time, I’d offer this caution: if you’re consuming a protein shake most days but otherwise aren’t eating a variety of complete proteins—ideally animal based—you should aim to diversify your protein sources.
You’ll find a variety of keto shakes on the market being sold as complete meal replacements. I have to admit I’m leery of these, perhaps because they harken back to traditional diet shakes promising quick weight loss, nutrition be damned. A popular diet brand that shall remain nameless—you know the one—is even marketing keto shakes now.
Since whey protein powder is already so convenient, I’d suggest whipping up a quick smoothie with veggies and a few high-antioxidant berries, plus some MCT oil if that’s your thing. However, if you can find a meal replacement shake with ingredients that pass your personal bar, I’m not going to tell you no. Just use them sparingly, not to regularly replace meals of whole foods.
My favorite basic smoothie: Keto-Friendly Chocolate Protein Smoothie (I usually add a big handful of baby spinach too!)
If a plate of cheese and crackers is what you crave the most, a couple brands make seed-based crackers that are actually pretty tasty. On the other hand, you can just get crackers made of dehydrated cheese and double down. Every year at the various conferences I attend there are more and more chip substitutes made with unconventional ingredients like chicken. Unfortunately, there isn’t any way to make popcorn keto (sorry), and I’ve yet to see a good keto pretzel, although I’m sure someone’s working feverishly on it.
My sense is that when people want snack foods, it’s really the crunchy texture and salty taste, and the easy, even mindless, quality that they crave. Unlike the breakfast foods, it’s not so much an emotional or nostalgic attachment to specific foods. For those reasons, I think this is one category where it’s usually just as easy and satisfying to find different snack options altogether rather than seeking out keto-fied versions of the old SAD foods.
Try this instead: Bacon Guacamole with Cheddar Chips
Keep It In Perspective
At the end of the day, it’s all about choices. We live in a food environment where temptation is everywhere. Our lives are too often over-busy and over-stressed, and sometimes reaching for a convenience food option is something we depend on.
Let me be very clear: I’m not suggesting that these are on par nutritionally with whole, “real” foods, nor do I think they should be staples in your diet. Of course, it’s best to treat these foods like occasional treats or fallback rations. If being able to grab convenience foods here and there makes keto living possible for you, then go for it. Just be intentional about it, and don’t let it become a slippery slope. As you become more accustomed to keto, you might find yourself reaching for them less frequently.
What say you? Which keto convenience items, if any, do you enjoy? Have your choices changed over time? Thanks for reading.

Have you been thinking about going keto—or recommitting to a keto routine? Are you looking to lose extra pounds? Enhance your fat-burning ability and metabolic flexibility? Improve your energy levels and general well-being to kick off summer?
Then you’ll want to join us for the June Keto Reset. It’s one month of personal guidance, exclusive resources, and fantastic giveaways. Best of all, it’s totally free. All you do is sign up.
I wrote The Keto Reset Diet to help people reach the pinnacle of metabolic flexibility, where they can harness the power of fat and ketones for energy (along with glucose as needed, of course). It’s another level of metabolic flexibility even beyond the scope of the Primal Blueprint fat burning. I strongly believe that it’s in most people’s best interest to periodically dip into ketosis and do a Keto Reset at least once or twice per year. Of course, as so many of you have learned, it’s possible to achieve tremendous gains to health, body composition, fitness, cognition, and general wellness by following a traditional Primal eating pattern (which puts most people in the range of 50 to 150 grams per day of carbs, give or take). Nevertheless, research and anecdotal evidence continues to shed light on the unique benefits that come from being in a state of ketosis at least some of the time.
My team and I put together this June Keto Reset to offer clear guidance and helpful resources as you go keto, so you’ll begin summer set up for total success….
What You’ll Get
Throughout the month of June you’ll receive two emails a week from yours truly with exclusive guidance, tips, and recipes for going keto the right way. You’ll learn how to optimize fat burning and get the results you’ve always wanted. Heads up: You won’t find these resources on the blog. (And for those of you who did the January Keto Reset Kickoff, the June experience is completely new—from top to bottom, so join us again!)
But that isn’t all. I’ll also send you other food lists, recipes, a Keto Reset Journal and Keto Reset Guide To Calculating Your Macros (a printable guide that you can hang on your refrigerator). You’ll have everything you need for a successful Keto Reset.
Plus, the whole month of June I’ll be running prize giveaways on our social channels and bringing you new Primal- and keto-friendly recipes from Mark’s Daily Apple, Primal Kitchen, and select partners. Finally, I’ll be giving away one GRAND PRIZE (look for the announcement soon!) to one lucky person who signs up for the June Keto Reset.
Simply sign up now at www.primalkitchen.com/pages/keto-reset. Enter your email to register. (You don’t need to purchase anything to participate.)

A couple months ago, a study came out that seemed to show that cheating on your keto diet with a high-carb meal opened you up to severe blood vessel damage. Nine healthy, normal weight adults followed a keto diet (70% fat, 20% protein, 10% carbs). Then they ate a high-carb “cheat meal,” measured their blood sugar, and measured their endothelial microparticles—a marker of damage to the endothelial lining and potential harbinger of impaired vascular function. Their blood sugar went way up, and so did their endothelial microparticle count, leading researchers to conclude that keto dieting makes people more susceptible to hyperglycemia-induced endothelial damage.
So, is keto cheating unhealthy? Let’s take a closer look….
My Analysis Of the Study:
Here’s why I don’t think this study applies to most of you:
These people were on keto diets, but they weren’t keto-adapted (let alone fat-adapted). They’d only been doing the diet for a week. Bare minimum, it takes three weeks to a month for full keto-adaptation to occur—and often longer. We’d have to see what happens to endothelial microparticle count when someone who is fully keto-adapted is exposed to higher carb intakes.
The “cheat meal” was 75 grams of pure glucose. This is the oral glucose tolerance test—the disgusting, cloyingly sweet drink they give people to test for diabetes. It measures your ability to handle pure glucose. It’s not a meal. It’s not actually food even. There are no mitigating micronutrients. There are no other macronutrients included. It’s just a shot of pure sugar, down the hatch. I don’t know about you, but that’s not my preferred method of a high-carb cheat meal.
However, it does illustrate the importance of sticking with the diet—any diet—for way longer than a week before assessing the effects or stepping out to indulge.
Look at the big picture. Acute perturbations to endothelial homeostasis can look bad in the short term and good over time. Hell, when you ask overweight women to engage in a single bout of high intensity exercise, their endothelial microparticle count goes up just like it went up for the guys in this study who drank the glucose water. They “damage” their vascular function. But if they keep training regularly, their endothelial microparticle count goes down. Acute stressors can look bad when applied once and awesome when applied consistently. That’s not to say that drinking 75 grams of glucose consistently will suddenly become healthy. I’m just showing how looking at a single short term reaction doesn’t give the entire story, or even accurately portray the effects of the same stimulus applied consistently over the long term.
A Better Perspective On Cheat Meals
Cheat meals can actually help you lose more weight. In one study, women were placed on a cyclic diet consisting of three phases. For each phase, they reduced calories for 11 days followed by 3 days of ad libitum (i.e. at one’s pleasure) eating. After the three phases, they’d lost an average of 8 kg (about 17 lbs) of pure body fat. This surpassed the amount predicted by calories in, calories out. This study didn’t employ all-out cheat days, or call them cheat days, but the concept of “ad libitum” is pretty similar.
If you cycle in high carb days or high carb meals into your keto diet, and you end up getting leaner and performing better in the gym because of it, are you really hurting yourself? Are you really setting your vascular system up for impending doom? I doubt it. One of the best ways to improve endothelial function is to lose excess body fat. Whatever helps you get to that goal should also improve vascular function.
If You’re Going To Cheat On Keto:
Get fully adapted.
The people in this study were not keto-adapted. They’d only been eating the diet for a week before taking the test. Stay with the diet for two months—strictly—before venturing out with cheat days.
Don’t cheat with an oral glucose tolerance test.
While some folks undoubtedly get off on drinking 75 grams of pure glucose, there are better ways to cheat. Like with food. Also, food tends to include mitigating factors—phytonutrients, fiber, vitamins, minerals—that improve the metabolic response to the macronutrients contained therein. For instance, including some natural cocoa in the cheat meal can drop your endothelial microparticles by 60% alone.
Be relatively lean and experienced.
Cheat days are more effective for fairly lean-ish people to kickstart the loss of those last few pounds. They’re designed for long-time keto eaters to replenish glycogen stores and improve training. They’re designed for people who have been strict for long enough that they just need a break. They just aren’t going to work the same for obese people who’ve been keto for a little while who still have a lot of easy weight to lose on strict keto.
Cheat after a big workout.
Exercising increases insulin sensitivity. And if you lift heavy things, you increase something called non-insulin dependent glucose uptake in the muscles. That means your muscles can actually refill their glycogen content without using insulin to do it. If you’re keto and want to incorporate high carb meals/days or cheat meals, legitimate training is pretty much required. After all, why do you need the carbs if you’re not training?
Cheat if you need it.
If things are stalling, and you’ve tried being even stricter to no avail, perhaps momentarily loosening up with a cheat meal is exactly what you need. Read this post to get the lowdown on why carb refeeds can help break weight loss stalls and how to do them.
This study shouldn’t be ignored. Big boluses of sugar are never a good idea, especially when you’ve only been eating low-carb or keto for a week and have yet to adapt. I find it plausible that such excursions can induce acute damage to the vascular system in anyone with impaired glucose tolerance—even if that glucose intolerance is transient, as it is in short term keto dieters—but I don’t think it means much for people with good heads on their shoulders who do keto the right way.
What do you think, folks? Do you cheat on your diet, whether you’re keto or just Primal? What steps do you take to make sure you’re getting the most out of your dietary excursions?
Thanks for reading, everyone. Take care!

There are a lot of possible reasons each of us eats the way we do. We like the way it tastes, or the memories it conjures, or maybe because we were raised eating that way. Perhaps certain foods make us feel good and energized — or an alternative food makes us feel crummy, so we avoid it. We might have allergies, sensitives, and intolerances that lead us to steer clear of big sections of the supermarket, and we may make certain choices because they align with our personal moral compass. And, of course, we can’t discount the fact that certain…

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?
We know that diet—what and how much we eat—can profoundly affect our hormones. This is true for both women and men. One of the reasons people are so excited about ketogenic diets is specifically because keto shows promise for helping to regulate hormones and improve cellular sensitivity to hormones such as insulin and leptin.
At the same time, women’s hormones are especially sensitive not only to dietary changes but also to downstream effects such as body fat loss. Furthermore, one of the ways women’s bodies respond to stressors is by turning down the dial on our reproductive systems. It’s reasonable to hypothesize, then, that women might have a tougher time adapting to or sustaining a ketogenic diet. Keto can be stressful depending on one’s approach, and that might negatively impact women’s reproductive health. But do the data actually bear that out, or is so-called “keto period” more misplaced hype than genuine fact?
Note that throughout this post, I’m going to use the term “reproductive health” to refer to all aspects of women’s menstrual cycle, reproductive hormones, and fertility. Even if you aren’t interested in reproducing right now, your body’s willingness to reproduce is an important indicator of overall health. When your reproductive health goes awry—irregular or absent periods (amenorrhea) or hormone imbalances—that’s a big red flag. Of course, post-menopausal women can also experience hormone imbalances that affect their health and quality of life (and low-carb and keto diets can be a great option for them).
Menstrual Cycle 101
Let’s briefly review what constitutes a normal, healthy menstrual cycle, understanding that everybody’s “normal” will be a little different. A typical cycle lasts from 21 to 24 days on the short end to 31 to 35 days on the long end, with 28 days being the median. Day 1 is the first day of your period and begins the follicular phase, which lasts until ovulation. Just before ovulation, levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), and estradiol (a form of estrogen) spike. Next comes the luteal phase covering the approximately 14 days from ovulation to menses. LH, FSH, and estradiol drop, while progesterone rises. Estradiol bumps up again in the middle of the luteal phase. If a fertilized egg is not implanted, menstruation commences, and the whole cycles starts over again. All this is regulated by a complex communication network under the hypothalamic–pituitary–gonadal (HPG) axis, which is closely tied to the actions of the adrenal (the A in HPA axis) and thyroid glands.
Across the cycle, fluctuations in body weight are common as fluid is retained and then released along with shifts in estrogen and progesterone. Changes in blood glucose are also normal, and insulin-dependent diabetics often find that they need to adjust their dose at different times of their cycles to keep their blood sugar in check. The most common pattern is higher blood glucose readings in the pre-menstrual period (the second half of the luteal phase), and lower readings after starting your period and before ovulation. This is generally attributed to the fact that progesterone, which is highest during the luteal phase, is known to reduce insulin sensitivity. However, different women experience different patterns, which can also be affected by other factors such as oral contraceptive use.
Normal fluctuations in insulin resistance and blood glucose can mean that women get lower ketone readings at certain times of the month than others. When these occur premenstrually—and so they tend to coincide with a period of (transient) weight gain and food/carbohydrate cravings—women often feel as though they are doing something wrong. Rest assured that these variations reflect normal physiology.
The many factors that affect your cycle and the levels of your sex hormones include: other hormones, gut health and microbiome, metabolic health (e.g., insulin sensitivity), environmental toxins, stress, sleep, immune health, nutrient deficiencies, activity level and energy expenditure, and age. Each affects the others, and all (except age of course) can be affected by diet. It’s no surprise, then, that it can be extremely difficult to pin down a root cause of menstrual changes or reproductive issues.
What the Research Tells Us About Keto and Menstruation
As I said at the outset, there are lots of anecdotes, both positive and negative. In my experience, most women whose cycles seem to go crazy when they start keto find that things get back to normal—and often a better version of normal—after a few months.
First, it’s tricky to determine the effects of keto per se, since many people combine a ketogenic diet with calorie restriction (intentionally to lose weight or unintentionally due to the appetite suppressing effects of keto) and with fasting (intermittent and/or extended). Each of these can independently impact the factors listed above, lead to weight loss, and affect the menstrual cycle and reproductive health.
So, is there any evidence that keto itself causes changes to menstruation?
The scientific evidence is scant….
The one statistic you’ll see floating around the interwebs is “45% of (adolescent) females experience irregular menstrual cycles on keto.” This statistic comes from one small study of adolescent girls using a therapeutic ketogenic diet to treat epilepsy. Six of the twenty girls reported amenorrhea (loss of period) and three were diagnosed with delayed puberty. However, the ketogenic diet used for epilepsy is different and usually much stricter than an “everyday” keto diet needs to be, and epilepsy is frequently associated with menstrual dysfunction regardless of diet.
To extrapolate the findings of this study and argue that nearly half of teenage girls (or women generally) are likely to experience menstrual problems from going keto is a huge leap.
The fact is, I’m unable to find any studies done in healthy human females (or mice for that matter) demonstrating that otherwise normal menstrual cycles are disturbed by going keto.
5 Ways Keto-Related Factors *Might* Affect Your Menstrual Cycle
With the limited amount of research looking directly at keto and menstruation, let’s look first at whether there are direct effects of carbohydrate restriction or elevated ketone production on the menstrual cycle. Those are the defining characteristics of keto and what differentiates keto from other ways of eating. Then we can examine indirect effects that occur due to factors such as weight loss. These are not unique to keto, though they might be more likely on a ketogenic diet compared to other ways of eating.
There is no real body of evidence that looks at ketogenic levels of carb restriction and menstruation, but there are some clues. In this small study, functional hypothalamic amenorrhea (FHA) was associated with dietary fat restriction; women with FHA actually ate non-significantly more carbs than matched controls and nearly identical total calories. Likewise, in this small study, FHA was associated with lower fat intake but no significant difference in carb intake.
This meta-analysis looked at the effect of low-carb (not keto) diets on markers of reproductive health among overweight women. The researchers found four studies that examined effects on menstruation; all showed improved menstrual regularity and/or ovulation rates. Of six studies that looked at levels of reproductive hormones, five reported significant improvements.
Carb restriction also results in decreased insulin production. Hyperinsulinemia and insulin resistance are frequently associated with polycystic ovarian syndrome (PCOS), one of the leading causes of female infertility and a frequent cause of menstrual irregularity. There is currently a lot of interest in using keto to treat PCOS, but only one small study has so far directly tested the effectiveness of a ketogenic diet to treat PCOS, with positive results.
No studies have looked at the direct effects of ketones on menstruation.
Of course weight loss is not unique to keto, but keto can be very effective for weight loss. Some women experience rapid weight loss when first starting a keto diet. Weight loss in and of itself can impact menstruation through a variety of pathways. A key way is by reducing the hormone leptin. Leptin’s main job is to communicate energy availability to the hypothalamus—high levels of leptin tell the hypothalamus that we have enough energy on board, which also means we can reproduce. Low leptin can disrupt the menstrual cycle and is linked to hypothalamic amenorrhea.
Body fat loss can also affect estrogen levels since estrogen is both stored and produced in adipocytes (fat cells). While fat loss in the long term will decrease estrogen production, it is possible that rapid fat loss might temporarily raise estrogen levels and can also affect estrogen-progesterone balance. These transient changes in estrogen levels might underlie some of the menstrual irregularities women report.
Stress can impact the menstrual cycle in myriad ways. Cortisol acts on the hypothalamus and pituitary glands, affecting hormone levels, sleep, immune function, and gut health, to name a few. Diets can be a source of stress, both at the physiological and psychological levels. Keto has a reputation for being especially stressful because it is more restrictive than other low-carb diets, but this can be mitigated by following the Keto Reset tips for women.
Thyroid dysregulation is another common cause of menstrual irregularities, and there remains a pervasive belief that keto is bad for thyroid health. Indeed, the thyroid is sensitive to nutrient deficiencies and caloric restriction, and thyroid hormones, especially T3, do frequently decline on keto. However, as Mark has discussed in a previous post, changes in T3 levels might not be a problem, especially in the absence of other problematic symptoms. Moreover, many practitioners now use keto as a cornerstone in their treatment of thyroid disorders.
What Should I Take From These Findings?
The first takeaway: there just isn’t much direct evidence about how keto might affect your menstrual cycle, positively or negatively. We have some studies suggesting that low-carb diets improve some aspects of menstruation and reproductive health, but keto is more than just another low-carb diet. Ketones themselves have important physiological properties, such as being directly anti-inflammatory, which might positively impact women’s reproductive health.
Second, the ways that keto is likely to (negatively) affect menstruation aren’t unique to keto, they’re common to any diet: hormone shifts mediated by energy balance, stress, and weight loss.
Furthermore, since keto is so often combined with caloric restriction, time-restricted eating, and fasting, even the anecdotal evidence might not be able to tell us all that much. If a woman is eating ketogenically, in a big caloric deficit, and doing OMAD (one meal a day), and her leptin plummets, how are we to know what really caused it? We don’t have good evidence that otherwise healthy women start a well-executed ketogenic diet and end up messing up their menstrual cycles.
That said, women do need to be cognizant of the sum total of the signals they are sending their bodies when it comes to energy availability and stress. A lot of women come to the keto diet with a history of adrenal, thyroid, metabolic, and reproductive issues. It’s important that they’re extra careful about how they approach keto. Done correctly, it might be just what the doctor ordered. I encourage any woman who’s dealing with other hormonal issues to work with a medical practitioner to tailor a keto diet to her unique needs.
But I’m Telling You, Keto Made My Period Go Haywire!
Ok, I believe you, really! But changes do not necessarily equal dysfunction. It is normal to experience hormone fluctuations when you make a massive—or even a relatively small but important—shift in your nutrition. Sometimes those fluctuations are unpleasant or unwanted, such as a period that lasts 14 days or one that arrives a week before you planned while you’re on vacation. However, that doesn’t make them bad from a health perspective. We need to respect that our bodies are dynamic systems. Changing the input will invariably change the output, and the system might need a few months to adapt to a new normal.
If your cycle goes wonky but you’re otherwise feeling good, give it a few months to sort itself out. If after a few months it’s still all over the place (or definitely if you’re having other disruptive symptoms), enlist help. In the meantime, check to make sure you’re not short-changing yourself nutritionally or calorically. Scale back on fasting efforts, and consider shifting more toward a traditional Primal way of eating.
At the end of the day, if you go keto and experience negative effects, stop. Keto is super hyped right now, but if your body is sending you clear signals that keto is not a good approach for you at this time, don’t do it. You can always try again later. It might be that your first attempt at keto didn’t work, but with a few adjustments and some experimentation over time you can find a version of keto that works for you.

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.
Do I buy into the idea that fiber is important because it is every human being’s responsibility to produce as much colonic bulk as humanly possible? No.
Do I think we should be consistently pushing the limits of our digestive tracts, performing feats of bathroom heroism so momentous they border on Herculean, and making sure the toilet bowl buckles beneath us? No.
The real value of fiber lies not in its coarseness, its tendency to form colonic bulk, to keep us topped off. The true value lies in its fermentability. A fermentable fiber is a prebiotic fiber—fiber that feeds our gut bacteria.
I will, however, explain why we need to be feeding our gut bacteria. Our gut bacteria form a physical barrier against incursions and colonization by pathogenic bacteria; they take up room along the gut lining so pathogens can’t. If we don’t feed our gut bacteria with prebiotics, it won’t be around to protect us. After antibiotic treatment where both good and bad gut flora are indiscriminately targeted and wiped out, pathogenic obesity-promoting bacteria take advantage of the open space. That’s a worst-case scenario, but it shows what can happen when the harmony of the gut is disturbed by antibiotics or, to a less extent, a lack of fermentable prebiotic fibers.
Gut bacteria also convert antinutrients like phytic acid into nutrients like inositol. The almond meal-obsessed keto eater would do well to have a powerful gut biome set up to convert all that phytic acid to inositol.
Now, some writers will come up with specific blends of fibers, powders and gums to create the “optimal” prebiotic diet for your gut bacteria, but that’s pretty silly. The gut is a complicated place. We’ve barely begun to even identify all its inhabitants. To think we know the precise blend of isolated fiber that will make them flourish, and then act on that, is a mistake.
1) Almonds and Pistachios
Nuts are usually favored in health-conscious circles for a few reasons. They like the monounsaturated fat. They like the mineral profile, or the complete protein, or their ability to dissemble into nut meals and form baked goods. But what gets short shrift is the fiber content. Now, I can’t speak for other nuts, but almonds and pistachios in particular contain fiber with potent prebiotic effects. People who eat almonds and to an even greater extent pistachios end up with improved gut bacteria profiles.
2) Green Bananas
Ripe bananas are difficult to squeeze into a ketogenic diet. The green banana—an unripe one—is mostly resistant starch, a type of starch that cannot be digested and travels untouched until colonic bacteria metabolize it. It’s one of the best stimulators we know of butyric acid production. And sure, you could do a spoonful of raw potato starch to get your resistant starch, but the beauty of the green banana is that it also provides potassium, another nutrient that some find difficult to obtain and stay keto.
3) Wild Blueberries
Blackberries, boysenberries, raspberries, and strawberries are all loaded with fiber, and you should eat them. They’re lower carb than you think, they’re loaded with polyphenols, and topped with some real whipped cream they make a fantastic dessert. But wild blueberries are special. They’re smaller than other berries, which increases the amount of skin per ounce you get, and skin is where all the polyphenols and fiber lie. Heck, even the blueberry’s polyphenols have prebiotic effects on the gut biome.
A few years ago, I wrote a whole post on mushrooms. Suffice it to say, they’re quite wonderful, bordering on magical. I did not discuss the fiber they contain. It turns out that all the various mushroom polysaccharides/fibers, including beta-glucans, mannans, chitin, xylans, and galactans also act as potent prebiotics that improve the health of the host.
Your standard avocado has about 12-15 grams of fiber, if you eat the whole thing. I
Great with chili powder, salt, and lime juice, jicama is about 11 grams of carbs per cup, but half of those are inulin, a potent prebiotic fiber with a tendency to really ramp up butyrate production.
Onions are another fantastic source of inulin. They go into almost every dish of every cuisine, so there’s no excuse not to be eating onions.
I’ve been known to treat garlic like a vegetable, roasting an entire cast iron pan full until brown and sweet and chewy. They’re another great source of prebiotic fiber.
Broccolini is a major part of my favorite meal of the day—my Big-Ass Keto Salad. Broccoli (and cruciferous vegetables in general) has been shown to have modulatory effects on the gut biome.
12) Dark Chocolate
13) Animal Fiber
Obligate carnivores like cheetahs who don’t eat any plants (willingly) still have gut bacteria. These gut bacteria thrive on “animal fiber,” the gristle and cartilage and other bits of connective tissue that comprise a good 20-30% of the walking weight of a prey animal. Humans are not obligate carnivores, but eating the entire animal has been a mainstay of advanced hominid existence for millions of years. I find it very likely that something, someone, somewhere inside our guts is breaking down the animal fiber we eat—so you’d better be eating some!
Not so tough, is it? It’s not like I’m suggesting you load up on bran muffins, psyllium smoothies. I don’t want you dumping flax meal into everything or munching on those awful fiber gummies. Just eat some basic, healthy, low-carb plant matter—foods that don’t really scream “fiber”—and the rest will take care of itself.
What’s your favorite low-carb source of fiber? Let me know down below.

With the explosion of keto, there’s an ever growing constant stream of new information about the significant benefits, supposed risks, and varying “rules” for how to adopt a keto diet. As with most things, it’s easy to get sucked into information overload. (And that doesn’t even take into account the hype that unfortunately gets distributed like wildfire around the Internet.) You want sources you can count on for facts, reason, and utility. Here are eleven solid sources I’d recommend for intelligent commentary, sound science, and useful ideas.
Mark’s Daily Apple
Sure, this isn’t an exclusively keto blog. It’s a Primal living blog—with attention to all the components that figure into a healthy lifestyle and fulfilling life. But keto is a powerful tool I use within the Primal Blueprint template. As most of you already know, I approach keto specifically through a Primal lens—what I call a Primal-keto approach to keto living that prioritizes optimum nutrition with the least amount of pain, suffering and sacrifice. I know it’s been working for a lot of people, and I’ll continue to to write on it as well as all the other elements of a healthy life. Four particular resources I’d suggest to folks new to keto: the MDA Keto Hub, our Keto Recipes, the Primal Blueprint Keto Podcast, and our private Keto Reset Facebook Group. They’re all free resources for anyone to use and enjoy. For those who want to receive an additional Mark’s Daily Apple monthly email with exclusive information and commentary on keto, you can sign up below for the Keto Reset Digest (also free).
Virta Diet Blog
Virta Health is a groundbreaking health organization using keto to treat—even reverse—type 2 diabetes and associated metabolic disorders. The Virta Diet Blog is an must-read, providing a mix of cutting edge science, easy to understand articles regarding practical aspects of going keto, and inspiring success stories.
I love Amy Berger’s common sense approach to keto on Tuit Nutrition. She calls her approach Keto Without the Crazy, and that about sums it up. Her articles are long but very worth reading.
At Ruled.me you’ll find mostly long-form articles that contain a ton of information about the keto diet. The site also provides an extensive recipe collection and other resources.
Healthful Pursuit is the home of Nutrition Educator and keto guru Leanne Vogel. Leanne provides a blend of blog posts, videos, and recipes to help you go keto in a healthy way. Much of the content is focused on keto for women, but men and women alike can benefit from the info provided.
At Calories Proper, Dr. Bill Lagakos covers a wide range of topics related to nutrition, fasting, circadian biology, and much more. While it’s not a keto blog per se, keto is a frequent topic. In any case, you’re sure to learn a lot from the content here, which is heavily focused on reviewing and critiquing empirical research studies in an understandable way.
Ketogenic Athlete is a well-rounded blog for strength and endurance athletes who are interested in using keto for training and performance.
The MAF Files at philmaffetone.com
Dr. Phil Maffetone has been using low-carb and keto diets to help athletes achieve breakthrough athletic performance for decades. His 180-age formula is a cornerstone of my Primal Endurance approach to become and fat- and keto-adapted athlete. The MAF Files covers a variety of topics that will be of interest to Primal and keto athletes.
HVMN offers the only commercially available ketone ester supplement. The blog reflects their target audience: athletes and other high performers who are interested in using diet and lifestyle modifications—and possibly exogenous supplementation, of course—to harness the power of ketones.
Elana Amsterdam has long been one of my go-to sources for healthy, delicious paleo recipes, but more recently she has been using keto as part of her strategy to address her MS. I’ve never made an Elana’s Pantry recipe that wasn’t excellent. She also writes about a variety of topics related to health.
Christina Kurp shares how she used a combination of AIP and keto to fix her own health issues. Part wellness blog, part scrumptious recipe collection, Castaway Kitchen is a great resource for anyone looking for food inspo, especially if you have dietary restrictions.
Cast Iron Keto
Plainly put, Cast Iron Keto has food I like to eat: simple, delicious, keto-friendly. You’ll find lots of keto-fied classics here suitable for kids and non-keto types (making dinner that much easier).
Thanks for stopping in today, everyone. Have a favorite you didn’t see here? Share down below. Take care.

For today’s edition of Dear Mark, I’m answering three questions. First up, what can a person do to help their gut recover its barrier function after too many antibiotics? Are there any foods, supplements, or dietary strategies? Second, what can explain rapid fatigue during sprint sessions on a keto diet? Is this simply part of the deal, or are there modifications you can make? And finally, what do I do when I know I’m going to get a bad night’s sleep?
Mark – any idea how to cure leaky gut caused by overuse of antibiotics. Tried raw dairy for a month to no avail.
First of all, check out my post on leaky gut. Read through it and follow my suggestions for preventing and treating intestinal permeability. It’s a great place to start.
Then, let’s look at some other interventions that have been shown to improve recovery from antibiotic therapy. While most of the studies referenced don’t explicitly describe antibiotic-induced leaky gut, anything that improves gut function and restores healthy gut bacteria will also normalize leaky gut—since it’s the eradication of native gut bacteria that causes antibiotic-induced leaky gut.
Fermented dairy. You tried raw dairy. What about fermented dairy? While raw dairy has its merits, it’s fermented dairy that just works for recovery from antibiotics. Yogurt is a good option to try, although the evidence is a bit inconsistent. Kefir is probably better; it’s been shown to improve patients’ tolerance to triple antibiotic therapy during treatment for H. pylori infection. This is even worth consuming during antibiotic therapy, as many of the probiotic bacteria found in fermented dairy show resistance to common antibiotics.
Fermented vegetables like sauerkraut are also must-eats. The fermented cabbage contains ample amounts of L. plantarum, a bacteria strain that’s been shown to prevent antibiotic-related diarrhea in piglets (another omnivorous mammal). Good options exist in stores (check the refrigerated section; shelf-stable pickles and kraut aren’t lactofermented), and even more are available in farmer’s markets, but the best way to get the most bacteria-rich vegetable ferments is to make your own.
Supplemental probiotics are fantastic here, too: large doses of the desired microorganisms delivered directly to your gut. Some of the strains used in Primal Probiotics, like B. clausii and S. boulardii, have been shown to be effective against antibiotic-related diarrhea, so that could be a good choice.
Don’t forget the food for your gut bugs: prebiotics. You need to eat fermentable fibers and other prebiotics like resistant starch to support the growth and maintenance of the helpful bacteria that improve gut barrier function. Consider eating cooked and cooled potatoes, unheated potato starch, leeks, garlic, onions, green bananas, apples, pears, berries, and pretty much any fruit or vegetable you can get your hands on. Plenty of them are low-carb enough to work on a keto diet, if that’s your desire. Oh, and dark chocolate is a great source of fiber and polyphenols, which have prebiotic effects in the gut.
Incorporate intermittent fasting. Going without food for a spell gives your gut a break and induces autophagy, which can help with tissue healing.
Get dirty, too, to introduce potentially helpful bacteria. Go out and garden. Go barefoot at the park (do your due/doo diligence, of course) and practice tumbling, or roughhouse with your kids (or friends). Don’t immediately rush to wash your hands all the time (unless you’ve been handling raw meat and/or dog poop).
Whatever you do, don’t stress too much about the antibiotics you had to take. Stress is awful for gut health and you’ve already taken the antibiotics—which were probably necessary—so that ship has sailed.
If probiotics with prebiotics aren’t helping (or making things worse), you might want to try going the opposite direction—removing all plant foods and doing a carnivore diet for a few weeks. While I have doubts about the long term viability and safety of eschewing all plant foods, enough people have written to me about their great experiences resolving gut issues with a bout of carnivory that it’s worth trying.
When on a strict keto plan, why do I become so quickly fatigued while attempting a HIT sprint workout?
The first five seconds of a sprint are primarily powered by phosphocreatine (or creatine phosphate), a “quick burst” energy source that burns hot but disappears quickly. This is the stuff used to perform max effort Olympic lifts, short sprints, and other rapid expressions of maximum power. It doesn’t last very long and takes a couple minutes to replenish itself. A keto diet doesn’t affect our creatine phosphate levels. If anything, it should improve them if we’re eating meat.
After five seconds, anaerobic metabolism of muscle glycogen provides the lion’s share of your energy needs. The longer your sprint, the more glycogen you’ll burn. The less glycogen you carry in your muscles, the shorter your sprint. Because once you run out of creatine phosphate and glycogen, you’re left with aerobic metabolism—great for longer distances, not so great for max effort sprints.
Keto dieters tend to walk around with less glycogen in their muscles. If that’s the case, longer sprints will be harder.
If you want to keep sprinting:
Do shorter sprints. Try a 10-second hill sprint rather than a 20-second one. Really go hard. Heck, you can even do 5-second sprints and derive major benefits; just do more of them and make sure to recover in between. There’s no rule saying you have to sprint for 20-30 seconds.
Take longer rest periods. Give your muscles a chance to replenish more creatine phosphate (and take creatine or eat red meat and fish, which are the best sources of dietary creatine).
Eat 20-30 grams of carbs 30 minutes before a sprint session. See if it helps. Alternatively, you can eat the 20-30 grams of carbs after the sprint session to replenish lost glycogen stores (without really impacting your ketone adaptation, by the way).
Most people figure out their sprinting sweet spot while doing keto. They may have to play around with the dosages, durations, and rest periods, but you can usually make it work. Be open to trying new permutations.
If you knew you were going to have a poor nights sleep, what measures would you take to reduce some of the damage?
I would exercise hard that night. Normally, a bad night’s sleep tanks your insulin sensitivity the next day, giving you the insulin resistance and glucose tolerance of a diabetic. A good hard interval session the night before a bad night’s sleep, however, counters the next-day insulin resistance.
I would make the most of it. Don’t dawdle. Don’t beat yourself up because of the impending sleep deprivation. It’s going to happen. You have to accept it, not let it destroy you.
Enjoy it. A little-known acute treatment for depression is sleep deprivation. That’s right: a single night of sleep deprivation has been shown to ameliorate depression in patients with clinical depression. Sometimes the effect lasts up to several weeks. It’s not a long term or sustainable fix for clinical depression, obviously, and you can’t do it every single night—chronic sleep deprivation is a major risk factor for developing depression—but it can improve your mood if you give in to it.
I would set out a jar of cassia cinnamon. I always add cassia cinnamon to my coffee in the morning after bad sleep; cassia cinnamon the day after a bad night’s sleep attenuates the loss of insulin sensitivity and glucose tolerance.
That’s it for today, folks. Thanks for writing in and reading! If you have any input on today’s round of questions, let me know down below.

Biological systems are self-maintaining. They have to be. We don’t have maintenance workers, mechanics, troubleshooters that can “take a look inside” and make sure everything’s running smoothly. Doctors perform a kind of biological maintenance, but even they are working blind from the outside.
No, for life to sustain itself, it has to perform automatic maintenance work on its cells, tissues, organs, and biological processes. One of the most important types of biological maintenance is a process called autophagy.
Autophagy: the word comes from the Greek for “self-eating,” and that’s a very accurate description: Autophagy is when a cell consumes the parts of itself that are damaged or malfunctioning. Lysosomes—members of the innate immune system that also degrade pathogens—degrade the damaged cellular material, making it available for energy and other metabolites. It’s cellular pruning, and it’s an important part of staving off the worst parts of the aging process.
In study after study, we find that impairment to or reductions of normal levels of autophagy are linked to almost every age-related degenerative disease and malady you can imagine.
- Cancer: Autophagy can inhibit the establishment of cancer by removing malfunctioning cellular material before it becomes problematic. Once cancer is established, however, autophagy can enhance tumor growth.
- Diabetes: Impaired autophagy enables the progression from obesity to diabetes via pancreatic beta cell degradation and insulin resistance. Impaired autophagy also accompanies the serious complications related to diabetes, like kidney disease and heart failure.
- Heart disease: Autophagy plays an important role in all aspects of heart health.
- Osteoporosis: Both human and animal studies indicate that autophagy dysfunction precedes osteoporosis.
- Alzheimer’s disease: Early stage Alzheimer’s disease is linked to deficits in autophagy.
- Muscle loss: Autophagy preserves muscle tissue; loss of autophagy begins the process of age-related muscle atrophy.
Okay, so autophagy is rather important. It’s fundamental to health.
But how does autophagy happen?
The way it’s supposed to happen is this:
Humans traditionally and historically lived in a very different food environment. Traditionally and historically, humans were feasters and fasters. While I don’t think our paleolithic ancestors were miserable, wretched, perpetually starving creatures scuttling from one rare meal to the next—the fossil records show incredibly robust remains, with powerful bones and healthy teeth and little sign of nutritional deficits—they also couldn’t stroll down to the local Whole Foods for a cart full of ingredients. Going without food from time to time was a fundamental aspect of human ancestral life.
They worked for their food. I don’t mean “sat in a cubicle to get a paycheck to spend on groceries.” I mean they expended calories to obtain food. They hunted—and sometimes came back empty handed. They dug and climbed and rooted around and gathered. They walked, ran, stalked, jumped, lifted. Movement was a necessity.
In short, they experienced energy deficits on a regular basis. And energy deficits, particularly sustained energy deficits, are the primary triggers for autophagy. Without energy deficits, you remain in fed mode and never quite hit the fasted mode required for autophagy.
Now compare that ancestral food environment to the modern food environment:
Almost no one goes hungry. Food is cheap and plentiful, with the tastiest and most calorie-rich stuff tending to be the cheapest and most widely available.
Few people have to physically work for their food. We drive to the store and walk a couple hundred steps, hand over some money, and—BOOM—obtain thirty thousand calories, just like that. Or someone comes to our house and delivers the food directly.
We eat all the time. Unless you set out to do it, chances are you’ll be grazing, snacking, and nibbling throughout the day. We’re in a perpetually fed state.
The average person in a modern society eating a modern industrial diet rarely goes long enough without eating something to trigger autophagy. Nor are they expending enough energy to create an energy deficit from the other end—the output. It’s understandable. If our ancestors were thrust into our current situation, many would fall all over themselves to take advantage of the modern food environment. But that doesn’t make it desirable, or good for you. It just means that figuring out how to trigger autophagy becomes that much more vital for modern humans.
Here are 7 ways to induce autophagy with regular lifestyle choices.
There’s no better way to quickly and reliably induce a large energy deficit than not eating anything at all. There are no definitive studies identifying “optimal” fasting guidelines for autophagy in humans. Longer fasts probably allow deeper levels of autophagy, but shorter fasts are no slouch.
2) Get Keto-Adapted
When you’re keto- and fat-adapted, it takes you less time to hit serious autophagy upon commencing a fast. You’re already halfway there.
3) Train Regularly
With exercise-related autophagy, the biggest effects are seen with lifelong training, not acute. In mice, for example, the mice who are subjected to lifelong exercise see the most autophagy-related benefits. In people, those who have played soccer (football) for their entire lives have far more autophagy-related markers of gene activity than people of the same age who have not trained their whole lives.
4) Train Hard
In studies of acute exercise-induced autophagy, the intensity of the exercise is the biggest predictor of autophagy—even more than whether the athletes are in the fed or fasted state.
5) Drink Coffee
At least in mice, both caffeinated and decaffeinated coffee induce autophagy in the liver, muscle tissue, and heart. This effect persists even when the coffee is given alongside ad libitum food. These mice didn’t have to fast for the coffee to induce autophagy.
Certain nutrients can trigger autophagy, too….
6) Eat Turmeric
Curcumin, the primary phytonutrient in turmeric, is especially effective at inducing autophagy in the mitochondria (mitophagy).
7) Consume Extra Virgin Olive Oil
The anticancer potential of its main antioxidant, oleuropein, likely occurs via autophagy.
Disclaimer: The autophagy/nutrient literature is anything but definitive. Most studies take place in test tube settings, not living humans. Eating some turmeric probably won’t flip a switch and trigger autophagy right away, but it won’t hurt.
Autophagy is a long game.
This can’t be underscored enough: Autophagy is a lifelong pursuit attained by regular doses of exercise and not overeating every time you sit down to a meal. Staying so ketotic your pee tests look like a Prince album cover, doing epic 7-day fasts every month, fasting every other day, making sure you end every day with fully depleted liver glycogen—while these strategies might be “effective,” obsessing over their measures to hit some “optimal” level of constant autophagy isn’t the point and is likely to activate or trigger neurotic behavior.
Besides, we don’t know what “optimal autophagy” looks like. Autophagy isn’t easy to measure in live humans. You can’t order an “autophagy test” from your doc. We don’t even know if more autophagy is necessarily better. There’s the fact that unchecked autophagy can actually increase existing cancer in some cases. There’s the fact that too much autophagy in the wrong place might be bad. We just don’t know very much. Autophagy is important. It’s good to have some happening. That’s what we have to go on.
Putting These Tips Into Practice
Autophagy happens largely when you just live a healthy lifestyle. Get some exercise and daily activity. Go hard every now and then. Sleep deeply. Recover well. Don’t eat carbohydrates you don’t need and haven’t earned (and I don’t just mean “earned through glycogen depleting-exercise”). Reach ketosis sometimes. Don’t eat more food than you need. Drink coffee, even decaf.
All those caveats aside, I see the utility in doing a big “autophagy session” a few times a year. Here’s how mine looks:
- Do a big training session incorporating strength training and sprints. Lots of intense bursts. This will trigger autophagy.
- Fast for two or three days. This will push autophagy even further.
- Stay busy throughout the fast. Take as many walks as possible. This will really ramp up the fat burning and get you quickly into ketosis, another autophagy trigger.
- Drink coffee throughout the fast. Coffee is a nice boost to autophagy. Decaf is fine.
I know people are often skeptical of using “Grok logic,” but it’s likely that most human ancestors experienced similar “perfect storms” of deprivation-induced autophagy on occasion throughout the year. You track an animal for a couple days and come up short, or it takes that long to make the kill. You nibble on various stimulants plucked from the land along the way. You walk a ton and sprint some, then lift heavy. And finally, maybe, you get to eat.
If you find yourself aging well, you’re on the right track. If you’re not progressing from obesity to diabetes, you’re good to go. If you’re maintaining and even building your muscle despite qualifying for the blue plate special, you’ve probably dipping into the autophagy pathway. If you’re thinking clearly, I wouldn’t worry. Obviously, we can’t really see what’s happening on the inside. But if everything you can verify is going well, keep it up.
That’s it for today, folks. If you have any more questions about autophagy, leave them down below and I’ll try to get to all of them in future posts.
