Collagen or whey. Which should you choose? For years, collagen/gelatin was maligned by bodybuilding ...
Today’s edition of Dear Mark is a relatively brief two-parter, but it’s a good one. First, I answer a question about HDL. Is higher good? Is higher (sometimes) bad? How does a person make sense of all the seemingly conflicting information? Then I explain how two statements about exercise and weight loss can be simultaneously correct and apparently contradictory. Is weight loss effective or useless for weight loss, or what?

Following the switch to Primal eating, people often share curious observations about their shift in taste. After a lifetime of eating sugar, grains, artificial flavors and hydrogenated oils, they’re often taken by surprise at the way their tastebuds react to a low-sugar, whole foods-based diet.
Granted, it doesn’t happen overnight, but it happens. Many say the effect sneaks up on them over the course of several weeks until one day they realize their sense of taste has gone into hyperdrive.
Then they look across the cubicle aisle and watch their coworkers inhaling bags of chips or uninterestingly sucking away on sugary beverages. And it occurs to them: all those wasted years as their tastebuds languished in processed monotony.
It’s one of the unexpected upsides of the Primal Blueprint diet: learning/relearning the nuance of real food flavor. The experience doesn’t just reflect a psychological shift either. Taste acclimatization is a real, measurable thing.
What do we know about the process? Quite a bit actually. Some of it rather surprising….Read More
I’ve written about what to eat. I’ve written about what not to eat. I’ve even discussed the benefits of occasionally eating things you “shouldn’t eat.” I’ve written about skipping breakfast, eating a big lunch, and skipping entire days of meals altogether. I’ve discussed sleeping low (carb) and punctuating a low-carb diet with occasional high-carb refeeds. But I haven’t written very much about when to eat.
I won’t tell you when to eat. There are many paths. You must find the one that takes you to your goal. But there are some physiological “truths” that impact how we process food depending on what’s happening in our lives which seem to apply to all humans. I’ll discuss several ways to think about meal timing, and then you can decide which concepts make sense for you and your life.Read More
People frequently wax sentimental for what they call “simpler” days—presumably times when the rules were fewer and clearer, when choices weren’t so overwhelming, when demands were less and common sense was more prevalent. Eating, of course, is no exception to this. If you listen to the dominant voices in the social-media-marketing-medical culture, it’s enough to ruin your dinner and make you feel guilty for skipping breakfast (Don’t buy the guilt trip). We’re fed contradictory studies, warned of the latest threats lurking in our food supply, told every bite squashes the life out of another ecosystem, and led through fluorescent-lit warehouses filled with more food options and label claims than one person should ever be reasonably expected to handle. It’s exhausting, frustrating and on certain days defeating. So what’s a reasonable approach in an age when anxiety too often overtakes enjoyment of eating?Read More
For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with IGF-1, growth hormone, and intermittent fasting? Some people say fasting increases growth hormones, while others say it decreases them. Who’s right? And what’s it all mean for our health? Next, how can a former CrossFitter ensure she’s maintaining her former fitness levels? And finally, what’s my take on Barre training and other “feminine” training schools?

Jean-Paul Sartre in one of his famous plays said, “Hell is—other people.” I think most of us might sympathize with that claim depending on the day and the person we’re dealing with. On the flip side, people can be the source of our greatest joys. His sentiment, regardless, speaks to the strong impact others can have on us. Whether we like it or not, we all live (and need to live) in some relation to others. None of us exist in a vacuum, and research on extreme isolation suggests the real hell on earth might be exactly that. So make no mistake—how people make us feel is not just the stuff of poetry and philosophy. Other people can and do influence our immediate physiology as well as our ongoing health. What does this process look like though? How does it play out in our lives? Let’s examine a few examples.Read More
