Dear Mark: Exercise-Induced Asthma, CBD for Diabetes, Warm-ups In the Morning

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with exercise-induced asthma? Is there anything we can do to lessen its impact and incidence? Second, is CBD oil helpful for diabetics? And finally, do bodyweight exercises always require warm-ups? What about workouts in general—do you need to warm-up before every single session?

After Six Months I Was In Remission

It’s Monday, everyone! And that means another Primal Blueprint Real Life Story from a Mark’s Daily Apple reader. If you have your own success story and would like to share it with me and the Mark’s Daily Apple community please contact me here. I’ll continue to publish these each Monday as long as they keep coming in. Thank you for reading!

I wanted to send an update since my last success story that you shared. But for the sake of the success stories (and first-time readers), I’ll give a little background info as well.

I was diagnosed with Crohn’s Disease back in 2000 at the young age of 13. For many years, I had many health-related ups and downs, and I was constantly in and out of remission. Not only did I suffer from painful gut-related issues, but I suffered from many other side-effects as well such as liver issues, extreme migraines, depression, thyroid nodules, rashes, and fragile hair and nails.

2 Meat, 2 Pepper Chili

Thanks to the good folks at Paleohacks for today’s recipe.

This rich keto chili is made with two types of beef and slow cooked in bone broth for stick-to-your-ribs heartiness. This rich and simple crockpot recipe combines sirloin steak, ground bison, sweet bell peppers, and smoky ancho chiles for a recipe that is anything but ordinary. Best of all, this chili can be prepped ahead of time for a meal that reheats in a pinch throughout a busy week.

The Real Deal On Keto Body Odor

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”

5 Hemp Oil Benefits For Health and Wellness

Have you tried hemp oil? After almost a century of being outlawed, hemp—a form of cannabis with extremely low levels of psychoactive THC—is now legal in the United States. This is big news for people interested in the therapeutic effects of cannabidiol (or CBD) because—while hemp doesn’t contain enough THC, the compound that provides the “high” of cannabis, or any other psychoactive compounds—it does contain cannabidiol (CBD). For years, all anyone talked about when they talked about cannabis was the THC content. Breeders focused on driving THC levels as high as possible and ignored the other compounds. Even pharmaceutical companies interested in the medical applications of cannabis focused on the THC, producing synthetic THC-only drugs that performed poorly compared to the real thing. It turns out that all the other components of cannabis matter, too, and foremost among them is CBD. CBD doesn’t get you high, but it does have big physiological impacts. These days, researchers are exploring CBD as a treatment for epilepsy, anxiety, and insomnia. They’ve uncovered potential anti-inflammatory, anxiolytic, and immunomodulatory properties. And now that it’s quasi legal, hundreds of CBD-rich hemp oil products are appearing on the market. What are the purported benefits of using CBD-rich hemp oil, and what does the evidence say? Although CBD research is growing, it’s still understudied and I expect I’ll have to update this post in the near future with more information. But for now, here’s a rundown of what the research says. 1) Hemp Oil For Anxiety Reduction Anxiety can be crippling. I don’t have generalized social anxiety, but I, like anyone else, know what it feels like to be anxious about something. It happens to everyone. Now imagine feeling that all the time, particularly when it matters most—around other people. The average person doesn’t consider the import and impact of anxiety on a person’s well-being. If CBD can reduce anxiety, that might just be its most important feature. Does it? Before a simulated public speaking event, people with generalized social anxiety disorder were either given 600 mg of CBD or a placebo. Those who received CBD reported less anxiety, reduced cognitive impairment, and more comfort while giving the speech. Seeing as how people without social anxiety disorder claim public speaking as their biggest fear, that CBD helped people with social anxiety disorder give a speech is a huge effect. This appears to be legit. A placebo-controlled trial is nothing to sniff at. 2) Hemp Oil For Sleep A 2017 review provides a nice summary of the effects of CBD on sleep: In insomnia patients, 160 mg/day of CBD increased sleep time and reduced the number of arousals (not that kind) during the night. Lower doses are linked to increased arousals and greater wakefulness. High dose CBD improved sleep; adding THC reduced slow wave sleep. In preliminary research with Parkinson’s patients, CBD reduced REM-related behavioral disorder—which is when you basically act out your dreams as they’re happening. More recently, a large case series (big bunch of case studies done at … Continue reading “5 Hemp Oil Benefits For Health and Wellness”
