I’m continuing my crusade of keto mythbusting. Recently, there was keto crotch, then keto bloat, and today I’m returning to one of the O.G. myths—keto body odor. Yes, it seems detractors of the keto diet are hell-bent on making you think your body will become a stinky, bloated mess if you dare to drop your carbs below 50 grams per day…but is it true? Here’s the spoiler: Yes, people in online keto diet forums occasionally complain about an unpleasant change in body odor when they first go keto. There is no scientific evidence that it actually happens, nor a clear, compelling explanation for why it would. Moreover, the anecdotal (and it’s all anecdotal) evidence suggests that if it does occur, it is rare and temporary. In other words, the whole idea of keto body odor seems to be exaggerated—shocking, I know. That said, significant dietary changes can result in other physiological changes that may manifest in a variety of ways. Since nobody wants to be the stinky kid, let’s take this opportunity to look at what might be plausible about keto body odor and what to do if you think you’ve been afflicted. What Causes Body Odor? First, let’s clarify what’s meant by “body odor.” In the medical literature, the term is used in reference to aromas associated with breath, urine, feces, vaginal secretions, sweat (usually from the axilla, or armpits), and general bodily essence as it were. Because it’s such a broad term, the causes are also extremely varied. For the purposes of this post, I’m going to use the term “body odor” to mean aromas from sweat and general bodily funk, since that’s what’s usually meant by keto body odor. Body odor arises when odorless compounds leave the body through glands in the skin and interact with microbes living on the skin’s surface. The microbes then release chemical compounds—what we actually detect as body odor. Typically, commercial deodorants target both pieces of the equation by using antiperspirants to minimize the excretion of the odor precursors and by creating an unfavorable environment for the microbes living on the skin. There is also a genetic component to how much individuals secrete compounds that cause body odor. Although a huge industry is built around trying to help people mask their natural odors—and suggesting that body odor is always the result of poor hygiene—bodily scents are actually quite important. Just as other animals do, humans use olfactory cues for recognizing kin, making judgments about others’ personality traits and attractiveness, and even for detecting fertility. Although we rarely recognize it, the data suggests that smell probably factors into all our face-to-face social interactions. Body odor can also result from illness. Before the use of sophisticated modern disease detection techniques, doctors were taught to use their sniffers as a diagnostic tool. Even today, smell can be an important clue that an individual is unwell. Often these odors emanate from the breath or urine, but certain infectious and metabolic diseases can be associated with … Continue reading “The Real Deal On Keto Body Odor”Read More
So you start your keto diet, and things are going well. You’re dropping excess fat, your carb cravings are noticeably reduced, your energy is steady throughout the day… and then one day you start to have the sneaking suspicion that you’re shedding more hair than usual. After a few days, it’s unmistakable: your hair is definitely falling out at an alarming rate.Read More
Much has been made of avocado oil’s ample nutritional benefits; however, its healing properties for skin and hair are too often overlooked. Sure, it’s hard to compete with improving lipid profiles and combating systemic inflammation, but this clean eating elixir offers advantages beyond interior health. While Mark has mentioned using avocado oil as a regular skin moisturizer, in truth there are many applications to nurture both skin and hair. Whether you’re interested in natural cosmetic ideas or simply basic skin and hair health, avocado oil offers a nutritive, non-toxic tool for your care routine.Read More
For today’s edition of Dear Mark, I’m answering several questions from the comment section of a previous post about my training supplementation. There were some fantastic ones.
I explain my favorite dinners and the latest I’ll eat it. After that, I give a couple ways to test (or not) the effects of these supposedly beneficial foods, nutrients, and supplements we all like discussing. I also tell how often I eat oysters, liver, and seaweed. Finally, I discuss collagen dosage and supplementation for IBS and Crohn’s.Read More
Morning, everyone. Hope you all enjoyed a happy and safe holiday. I’m turning over the reins to one of our Worker Bees today as I spend some time on a book project (more to come on that). I know many of you have asked about natural skin care ideas in the comment board, and we’ve got some great suggestions today. I hope you’ll welcome our Worker Bee to the fold (she just joined us recently) and offer up your own ideas below. (And for those who may have missed it, I shared several of my own favorites last spring.) Have a good end to the week.
Spend any amount of time perusing the shelves at your local supermarket or beauty supply store and you may notice that all the skin care products have something in common: a long ingredient list. I’m afraid to say most commercially-packaged bottles, jars, and tubes contain potentially harmful ingredients in the form of preservatives, stabilizers, artificial colors, and/or added fragrances, which could have negative long-term health effects when absorbed through the skin.Read More
I’ve always been a student of performance—in my athletic days and now. Whether it’s nutritional intake, training strategies, or supplement choices, this is where science comes to life for me. Over the years, I made this interest work for my fitness performance and now for my optimal health. It’s not about “hacking” the body’s functioning but understanding it from the ground floor up. This knowledge helps me live and age through life more on my own terms, which is exactly the way I like it.Read More
It’s easy to get into the habit of assuming that certain things “just happen” as we get older. As the years pile up, we brace ourselves for brittle bones, expanding waistlines, failing eyesight—and a propensity for falling asleep in front of the T.V.
Statistically speaking, they do loom largely. This is what we often see around us after all. But, of course, we know it’s not the whole story. We certainly can resign ourselves to a common fate, but that’s probably not why anyone is reading today. Most people who visit this blog (and definitely those who frequent it) want more. They want something better, and they’re willing to learn, move, and eat to get it.
And as with our bodies, so with our skin…
Recently, a reader inquired about gamma linolenic acid (GLA) and inflammation. Is GLA everything it’s made out to be? Is it something all of us should add to our diets? Can we obtain it through real foods, or do we need to rely on supplements? There’s certainly a lot of hype about GLA’s ability to heal chronic inflammation and even to facilitate an easier transition into menopause (something I’ll cover more in a follow-up post). For today, let’s take a closer look at GLA and the role it may play in anti-inflammatory nutrition.Read More
Conventional wisdom teaches us to accept our fate when it comes to hair loss. “Runs in the family,” we’re often told—and sometimes it does (but that’s usually not the full story). “It’s just part of getting older,” people say, too—and there we again find only partial truth at best.
But the Primal path is one of thoughtful scrutiny, not blind acceptance. While most people would file hair loss under aesthetic concerns (ranging from neutral to negative depending on social norms and personal views), it’s not always that innocuous. Let’s look today the bigger picture behind hair loss and the situations in which it signifies a genuine health concern.Read More
For today’s edition of Dear Mark, I’m answering three questions. First, is HDL all it’s cracked up to be? Is HDL always good? Is it the savior? Or is the story a bit more complicated? Next, what are some good probiotic options for treating acne? Do any exist? And last but not least, what’s the relationship of artificial sweeteners, insulin, appetite, and weight gain?
Let’s go:Read More
