Do Artificial Sweeteners Cause an Insulin Spike?

The notion that artificial sweeteners (and sweet tastes in general) might produce an insulin response is one of those murky memes that winds itself around the blogs, but it’s never stated one way or the other with any sort of confidence. I briefly mentioned the possibility of non-caloric sweeteners influencing satiety hormones in last week’s […]

Is Central Heating Related to Obesity?

Why are so many people in first-world countries so overweight? Why is metabolic syndrome so prevalent? The familiar contenders are diet and exercise – more specifically, the wrong kind of each. Both Conventional Wisdom types and nutrition nerds (myself included) agree that we’re doing something wrong in the kitchen and the gym, and that fixing […]

Dairy and Its Effect on Insulin Secretion (and What It Means for Your Waistline)

Insulin is an old, old hormone. Evolution has preserved its structure across hundreds of millions of years and hundreds of thousands of species. Fish, insects, reptiles, birds, and mammals all secrete insulin with fairly similar amino acid arrangements (insulin from certain species of fish has even been clinically effective in humans), so, clearly, it is […]

Monday Musings: Fructose, Not HFCS; Serenity Now, Death Earlier?

I’ve always been a bit leery about the overwhelming amount of attention paid to high-fructose corn syrup in the media and among the online health-conscious community. Sure, it’s bad stuff, maybe even especially bad when compared to other forms of sugar, but it is not enough to simply ditch the “corn sugar” and use “healthy […]

A Visual Guide to Yams and Sweet Potatoes (plus How They Fit Into a Primal Eating Plan)

Quick. What’s a suitable, Primal source of post-workout carbohydrates? If the title of this post and the picture to the right didn’t give you a hint then ask your nearest Primal enthusiast and they’ll tell you without batting an eye, “yams and sweet potatoes”. If, for whatever reason, you need some extra carbs “yams and […]

Is Samwise Gamgee Right About Potatoes?

Potatoes are controversial in the Primal and paleo world. They represent a bolus of dietary starch, which can wreak havoc on the insulin resistant, but they are undeniably whole, real foods that don’t require much processing beyond simple heating. Grains and legumes, on the other hand, are tiny, disparate sources of calories that need soaking, […]

Dial in Your Carb Count

Most folks who decide to give the Primal Blueprint 30-Day Challenge the old college try do so to correct an underlying health issue. Maybe their cardiologist’s recommended dietary plan hasn’t been improving their lipid numbers as promised, or perhaps they’re sick of fighting a losing battle with diabetes by submitting to a daily pharmaceutical cocktail […]

Dear Mark: Rapid Weight Loss

Mark,   I’m a big guy (okay, obese, if I’m being honest) who’s getting smaller fast. I adopted the PB a couple weeks ago, and I’ve already dropped twenty pounds, going from 300 to 280. Don’t get me wrong, I’m not complaining. I’m just confused. How does that work? You always hear that initial weight […]

Further Adventures with Leptin

I mentioned a few of the working hypotheses for avoiding leptin resistance in my posts last week, including fructose and lectin avoidance, getting adequate nightly sleep, and eating at or above maintenance levels – or at least throwing in periodic carb refeeds – but there’s even more involved in establishing a good relationship with your […]

Carb Refeeding and Weight Loss

Part of the allure of the Primal eating plan is that it’s effortless. There’s no calorie counting, no stressing over macronutrient intakes – eating PB simply means choosing to eat real, whole foods that man has been eating for tens of thousands of years. You can go higher carb or lower carb (I initially recommend […]

A Primal Primer: Leptin

Just about every physiological process occurring under the hood can be attributed to one hormone or another. Hormones are like software programs, directing our bodily processes, modulating our reactions to foods, and guiding energy metabolism and balance. We don’t consciously control our hormonal responses – that is, we don’t think to ourselves, “Hmm, let’s get […]

How to Quit Grains

Yes, they’re inextricably woven into nearly every aspect of our society. Dietary staple, cultural icon, sentimental fodder, patriotic symbol: it’s impossible to get away from them. However, just because they’re ubiquitous in our social environment doesn’t mean they deserve a place on your dinner plate. You know the multitude of reasons to quit grains. How […]

Dear Mark: The Low Carb Flu

Conquering carbs offers a whole constellation of rewards, not the least of which is a steady, brisk energy unlike most people have known before (well, maybe since the whirling age of 10 or so…). People tell me constantly that they can finally make it through the day without being down for the count every midafternoon. […]

The Lowdown On Lectins

Little known to the public at large. Little understood by the health community. Omnipresent in our conventional food culture. Proven to be at least mildly detrimental for everyone and downright destructive for the more sensitive (and often unsuspecting) among us. We’re talking lectins today: common natural agents on the one hand, cloaked thugs of the […]

The Definitive Guide to Sugar

You’d think this post would come with a blaring alarm, flashing strobe light or at least an ominous gong. Sugar, after all, gets little welcome around these parts. It’s on one hand a dastardly devil, shameless snare for many a man, woman and child. Beyond this luring, ignoble reputation, however, you’ll find (as is so […]

How Much Is Too Much?

Although the Primal Blueprint leaves ample room for individual determination, I do try to offer folks a clear picture of the impact different dietary and lifestyle choices have on their overall health picture. At times I even offer specific recommendations or ranges that readers can tailor to their particular needs and situations. I’m often asked, […]

The Question of Seasonality in Fructose Availability

Let’s continue the discussion from last time. Again, I apologize for any meandering. This is a big topic, and I think it helps to leave no stone unturned. Seasonal eating is currently pretty popular, perhaps even trendy in some circles. You’ve got the locavores, folks who only dine on meat and produce grown and harvested […]

Dear Mark: Sugar as Immune Suppressant

Dear Mark, Since going Primal last summer, my vegan buddy and I have some very explicit differences of opinion. I’m sure you can guess where they come up. Where we agree though is on the subject of sugar, especially refined sugar (syrups, honey, HFCS, table sugar, etc). Neither of us eat the stuff as a […]

What About a Zero Carb Diet?

Zero carb is getting (relatively) popular. A handful of valued MDA forum members eat little-to-no-carb, and several others probably imagine it’s ideal even if they don’t personally follow it. I wanted to address this because there seems to be some confusion as to how a zero carb eating plan relates to the Primal Blueprint eating […]

The Many Uses of Junk Food

A comment on my recent Coca-Cola post mentioned something I’d never previously considered: what if there were legitimate uses for un-Primal “food” items, things like bread, rice, peanut butter, or corn, that didn’t involve putting them in our mouths, chewing, and swallowing? In a previous post on pantry Primalizing, I suggested newcomers donate their off-limits […]
