Dear Mark: Ketosis and HIIT, Keto After Menopause, Inuit and Ketosis?

For today’s edition of Dear Mark, I’m answering a few questions from you folks. First, can a person maintain their high intensity interval training while starting a ketogenic diet? Is there anything you should watch out for? Second, is keto a good option for postmenopausal women? Though we don’t have any direct research on the subject, there is hope. And then we discuss the peculiar case of the Inuit and the missing ketones.

Is Keto for Everyone? Cautions, Caveats, and Contraindications

In a few months, I’ll be releasing a book extolling the virtues of a ketogenic diet. I’m currently several months into a ketogenic experiment, which is going well. I just wrote a Definitive Guide explaining why you should consider going keto. I’m on record as stating that everyone should dip into ketosis from time to time. You’d think I’d recommend that everyone go keto. Right?

There are caveats. There are contraindications. There are very good reasons for a person not to go keto, or at least to take a few extra precautions. Today, I’m going to tell you when you should exercise particular care when considering a ketogenic diet.

Dear Mark: Fat Roundup

Last week, I wrote about my 16 favorite fats. You had questions. For today’s edition of Dear Mark, I’ll answer some of them. First, I explain why my keto salad recipe didn’t include any dense protein. Second, I explain a few options for steaming heavy cream. Third, I tell where I get my mac nuts. Fourth, I discuss whether you should worry about dioxins in pastured eggs. And fifth, I address the question of dietary fat and fatty liver.

Dear Mark: Keto Follow-Up

For today’s edition of Dear Mark, I’m answering some questions from the comment board of last week’s Definitive Guide to Keto. You folks came up with some great ones. Is counting carbs in non-starchy vegetables still unnecessary on a ketogenic diet? What’s the connection between ketosis and “starvation mode,” and should we be worried? What if you don’t want to lose weight on a ketogenic diet?what modifications should you make? Are you in danger of blowing a breathalyzer test due to ketone metabolites on your breath? Can endurance athletes benefit from keto? Is cyclical ketosis preferable to constant ketosis? Are sugar alcohols ketogenic-friendly?

Dear Mark: Lead in Crock Pots, Norovirus in Smoked Oysters, and Creatine and Carbs

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with lead in crock pots? Some say lead leaches into the food when we cook with crock pots, while others aren’t so sure. And if the leaching of lead from crock pot ceramics into our food is, indeed, a problem, what equivalent product do I recommend? Next, a new study indicates that human norovirus is highly prevalent in oysters. Should we stop eating the canned smoked oysters from Crown Prince? And finally, do we really need to consume extra carbs with our creatine to get the full benefits?

Dear Mark: Ketosis and Cancer, Probiotic Dosing Patterns

For today’s edition of Dear Mark, I’m answering two questions. First up, is the ketogenic diet an effective cancer treatment? There’s a lot of hype in the media and online world about ketosis, but what does the research really say? Then, I discuss a few different probiotic dosing patterns. Should you take them every day? Is there a benefit to switching brands from time to time? Should you ever megadose probiotics? How did ancient and preindustrial people “supplement” probiotics?

Dear Mark: Ketosis and Testosterone, Dehydration Hormesis, and Isomalto-Oligosaccharides

For today’s edition of Dear Mark, I’m answering three questions. The first one concerns a potentially combative and controversial topic: ketogenic diets. What’s the deal with their effect on testosterone? You can find keto anecdotes across the web both inspiring and flaccid, but what, if anything, does the science say? Next, might there be a way to derive beneficial hormetic effects from acute bouts of dehydration? It seems like every other stressor can actually make a person stronger, so perhaps an otherwise wholly negative one like dehydration might as well. And finally, is the prebiotic fiber known as isomalto-oligosaccharide safe and/or good to eat?

Dear Mark: High HbA1c with Low Blood Sugar; Muscle Glycogen: Is It Local?; and Ketogenic Mosquito Repellant

For today’s edition of Dear Mark, we’ve got a three-parter. First, what could possibly explain an ardent and otherwise healthy low-carber with stellar postprandial (i.e. after a meal) blood sugar levels showing up with an HbA1c reading indicative of pre-diabetes? Who’s messing up — the test or Nancy herself? Next, that pastured chicken you’re about to eat may very well be local, but what about the glycogen in your quads? Is a muscle’s glycogen usable only by that muscle, or can it be shipped to nearby muscles as well? And finally, a reader reports suddenly becoming unattractive to mosquitoes upon adopting a low-carb diet and bouncing in and out of ketosis. Is he imagining things or is there a potential mechanism at play?

Dear Mark: French Press Coffee, Mid-Oleic Sunflower Oil, Peanuts, and a Keto Success Story

For today’s edition of Dear Mark, I’m answering three questions and sharing a quick, but awesome story from a reader. First, are French press, Turkish, and other unfiltered boiled coffee preparations unhealthy due to the presence of coffee oils in the finished product? They may raise LDL, which gets the conventional health experts hot and bothered, but there are other effects, too. Second, high-oleic sunflower oil was given the go-ahead in a previous post. What’s the story with mid-oleic sunflower oil? Third, with the recent study indicating that peanut/tree nut eaters enjoy improved mortality from all causes, should we take peanuts and most importantly peanut butter off the “no-go” list? And finally, a long term keto success story briefly mentioned in last week’s post writes in.

Dear Mark: Peripheral Neuropathy, Primal Compromises for Love, and Carbs in Ketosis

For this week’s edition of Dear Mark, I’m answering three questions. First up, what could be causing a reader’s peripheral neuropathy? Could it be gluten, B12 and/or B6 deficiency, diabetes, or inadequate vitamin D? The second question concerns homemade pasta, a beautiful woman, and a dilemma: do you indulge in the former to make the latter happy? My answer may surprise you, or it may not. I’m not sure. But I think you’ll find it helpful regardless. And finally, can carbs and ketosis co-exist? They certainly can, but there’s a little trick to make it work.
