For today’s edition of Dear Mark, I answer two good questions from readers. First up, I discuss the conditioning of bare feet for the purposes of walking across a multitude of surfaces. Believe it or not, much of the conditioning happens upstairs – in the brain. Then I give a little advice to a woman who’s having trouble losing stubborn weight after a miscarriage. She’s doing everything right without getting anywhere; could that actually be the problem?
In this week’s edition of Dear Mark, I’ll be covering three wide-ranging topics. First is acrylamide, the french fry toxin, the coffee carcinogen, the rat destroyer. It appears in almost every starchy item cooked or roasted at high heat, and it’s classified as a carcinogen. What do we do about it? Do we even have to worry about it? Next up are sprint alternatives for the person who loves to runny really fast every once in awhile but has a herniated disk that becomes aggravated shortly after said sprint. Sprinting is an important, beneficial activity, so long as you can do it pain and injury free, so I try to come up with a few worthy options. Then, I offer some advice to a man with gynoid – or lower body/hip/thigh – fat, most of which hinge on my suspicion that he’s low in free testosterone. Finally, I discuss the benefits – and drawbacks – of co-sleeping with your adult partner.
In today’s Dear Mark I discuss my favorite seaweed supplement, kelp granules, which aren’t really a supplement in the classic sense, but more of a food that you can treat as a supplement. Next, I give my thoughts on the latest study to suggest that an overweight BMI confers the lowest mortality risk in people. Finally, I handle a question from a parent currently trying to juggle sleep with exercise who wonders which to choose. It’s a tough question, to be sure, but I give my best attempt at a helpful, realistic answer.
Let’s get to it:
A few months ago, I addressed the role gender plays in how we respond to intermittent fasting. That post sparked a great discussion, and I’ve since received a fair number of emails from readers eager to learn other ways in which gender plays a role in our health and nutrition. One email in particular set me off on a round of research. So, a hat tip to you, Winifred, for giving me something to think, learn, and write about. I hope everyone finds it to be helpful.
As you may know, women and men store and metabolize fat differently from each other, and a 2008 paper (PDF) reviewed the evolutionary reasons for these differences. Here’s a summary of their findings and few other noteworthy factoids:
Last week’s Dear Mark discussing cold thermogenesis got some of you asking about brown adipose tissue. It’s a topic that deserves a full-fledged Primal Primer, especially since the idea of “good” body fat, a term many use to describe brown adipose tissue (BAT), is a foreign one. I mean, we’re talking about body fat here. Who wants it? Everyone I know is trying to get rid of their adipose tissue, not obtain more. It’s what brings many to this blog and what initiates this grand journey toward health and wellness. Even the people who say they “don’t care” about how they look would rather not have excess body fat, if only because it’s a marker of poor health or hormonal disregulation. We might acknowledge that we technically “need” some body fat to survive, but most of us will pass on any more than is absolutely necessary, thank you very much.
Before we get to the topics du jour I’d like to express my appreciation to everyone that participated in last week’s “Dear Readers” comment board. As I said, Mark’s Daily Apple, my books, and what I do is constantly informed by your thoughts and ideas. In other words, I couldn’t do this without you, so thank you for your feedback.
My team and I have compiled all of your ideas and have begun laying out a plan to give you what you want, and to reach the largest number of people possible. We’ll be checking things off the list in coming months, so stay tuned! Now on to today’s article…
From cruise ships to tweets to ice baths to supposedly hacked social media accounts, Dr. Jack Kruse the man is nothing if not controversial. But what about his ideas – do they have any merit? That’s what many of my readers have been wondering, along with how I feel about them. I’ve remained pretty silent on this matter, because Jack was doing his thing and apparently helping a lot of people in the process. I was doing mine and helping people in my own way. And all was well. Now, though, the questions are coming in droves, and I can’t really ignore them any longer.
A few months ago I wrote an article on How to Fuel a Marathon. In this week’s Dear Mark, I answer a reader’s question on how to improve a hydration recipe I recommended in that article. Then I cover a somewhat related topic: muscle cramps, and how to fix them and how to prevent them. Finally, I discuss Dr. Oz’s latest supplement miracle product – raspberry ketones. Sounds delicious, doesn’t it? Let’s go.
I am in training for my first ever marathon and have read your how to fuel a marathon. I did try the homemade hydration drink on my training run last week of 24km. I had 2 bottles of hydration and 2 bottles of plain water. I found the drink very sweet and you can definitely taste the black slat molasses. Swigging water straight after did help but it wasn’t overly pleasant.
I thought I would give it a try as I plan to use it on my race day which is July 1st. I was thinking of reducing the black slat molasses to just 1 tablespoon to see if it reduces the very sweet taste and perhaps increase the raw honey to 3 tablespoons, to see if it’s more palatable. Would this have any effect on keeping hydrated?
Also what can I use to keep hydrated on my long training runs? I find water is just not enough and I get thirsty and start to hit the wall around 17km. So basically, how do you fuel your training runs?
It would be great if you could give me some advice on this.
Hi again, everyone. Thanks for the comments and emails in response to my last post on menopause and hot flashes. I’m working on getting through your questions and hope to do several posts throughout the summer that speak specifically to issues that matter to women. Now that summer is here for most of the country, it seems like a good time to share a frequent reader issue this time of year.
I’m 35 and have been Primal for almost two years now. I’ve always been fairly thin, but going Primal in my eating and exercise has helped me get in better shape and build muscle. Unfortunately, I’m still plagued with some cellulite on the backs of thighs and hips. (Can I mention that I hate swimsuit season?) Why is cellulite so stubborn? Every “miracle cure” I’ve ever tried did next to nothing. Tell it to me straight – will this ever go away? Is there anything I can do? Thanks to you and Mark for everything you do with the Primal community.
Ah, sleep. Nothing like a good dose of the stuff, right? Losing even a single wink of your usual forty (or an hour, as the case may be) is enough to throw off an entire day.
But do you know who might love sleep more than anyone or anything? Our livers.
Yes, livers. Those fleshy multivitamins with an apparent propensity for fat accumulation function best on a good night’s sleep. New research is revealing exactly why shift workers and other chronically sleep deprived members of mankind tend to have problems with obesity, insulin resistance, diabetes, heart disease, and all the other popular features of metabolic syndrome: their livers aren’t processing fat efficiently, instead allowing fat to accumulate.
Before I begin, I want to make something clear: this is not your standard definitive guide to whatever. I’d like to be able to issue a proclamation regarding diet soda that stands the test of time immemorial, but I cannot. Research is still in its infancy, and exactly what diet soda does to those who drink it – if anything – is incredibly confusing. The one thing I can say with any certainty is that, while it’s unfair to say it will kill you or give your unborn child prenatal tumors or make you impossibly obese, you’re probably better off without diet soda. It tastes weird, the list of unpronounceable ingredients is too long for my comfort level, and I’ve seen one too many unsuccessful dieters that seem to live on the stuff.
There are two things to consider when making any conclusions about diet soda’s place in a healthy diet. Do the ingredients used in diet soda pose a threat to your short-term or long-term (or that of your offspring’s) health? Is it a kind of sugary methadone, impeding healthy eating by making it harder to kick the desire for sweet things in your mouth because, well, you’re constantly putting things in your mouth that mimic sugar? Let’s dig in.
