A few years ago, I wrote a post describing all the things that avowed Primal eaters can learn from p...
There was a time when food tracking was treated like a given, a necessary tool for anyone wanting to lose weight or better their health. Thankfully, there’s more nuance to that conversation now. The fact is, tracking your food can be a useful exercise for gaining more insight into what you’re putting in your body. It can also be a tedious endeavor that sucks all the joy out of eating.
If you’re going to invest the time—and it can be quite time-consuming if you include any variety in your diet—let’s make sure it’s not a waste.Read More
Yesterday, I explained the potential benefits and drawbacks of intermittent fasting for athletes. Maybe yesterday’s post intrigued you. Maybe you’re curious about this whole intermittent fasting thing but don’t want to sacrifice your performance in the gym or on the field.
What are my specific recommendations for athletes who wish to explore intermittent fasting? I’ve got twelve…plus some details about my own fasting and workout routine.Read More
To the average person, the idea of elite athletes skipping meals sounds like pure madness. Athletes are fine-tuned, well-oiled machines. Machines need fuel. You don’t see race car drivers running on empty to “promote training adaptations” in their vehicles. No, high performance requires high energy reserves.
Athletes need to eat, and eat well. Right?Read More
Last week, I explored the impact of all the various foods, beverages, and food-like substances people consume while fasting—and hoping to maintain a functionally fasted state in the post, “The Definitive Guide To What Breaks a Fast.” Does MCT oil break the fast? What about coffee, tea, or bone broth?
There were more than a dozen, and I even did a follow-up. Today I’m going to discuss whether commonly-consumed supplements break the fast.

As you and millions of other people embark on new dietary journeys, you’re going to hear a ton about calories.
“Calorie counting is everything.”
“If you aren’t counting calories, you won’t lose weight.”
“Just eat less calories than you expend.” For one, it’s “fewer.” Two, that’s not the whole picture.
These statements aren’t wrong exactly, but they offer an overly simplistic picture of the relationship between weight loss and calories. They ignore context. And context is everything, especially when you’re talking about calories and weight loss.
Most people (even many scientists) believe that the body composition challenge is a relatively simple equation: to lose weight you must reduce calories (either eat less or burn more), to gain weight you must add calories (eat more or burn less), and to maintain weight you keep calories constant (eat and burn identical amounts). Calories in over calories out.Read More
Metabolic flexibility is the capacity to match fuel oxidation to fuel availability—or switch between burning carbs and burning fat. Someone with great metabolic flexibility can burn carbs when they eat them. They can burn fat when they eat it (or when they don’t eat at all). They can switch between carbohydrate metabolism and fat metabolism with relative ease. All those people who can “eat whatever they want” most likely have excellent metabolic flexibility. So, why does it really matter, and how does it happen? Let’s get into the weeds today.Read More
People go keto for many different reasons. Some want to get better at burning fat so they have a clean, reliable source of steady energy at all times. Some people are treating a neurodegenerative disease, or trying to prevent one from occurring in the first place. Others just want to lose body fat, take advantage of the cognitive effects of ketosis, or stop seizures. Those are all common reasons to go keto. Another reason people go keto is for the benefits to physical performance.Read More
For today’s Dear Mark, I’m answering just one question from a reader. What are we to make of the new study purporting to show that saturated fat is the most harmful substance a liver can encounter? Should we remove all traces of it from our diets? Should we eat pure sugar? Quaff soybean oil? How relevant is an overfeeding study to a community of people dedicated to eating a sustainable, weight-reducing or -maintaining diet that includes saturated fat?
Let’s find out:Read More
Almost everyone has at least one dietary restriction. Maybe your religion or cultural traditions prohibit specific foods or food pairings. Maybe your physiological response to certain foods—an allergy or intolerance—prevent you from eating them. Or perhaps your immediate goals preclude a food’s inclusion in your diet.
Like every other diet, keto is already circumscribed by basic principles, which can make further limitations difficult to accommodate. But the benefits of going keto, at least for part of the time, are well-established and worth the effort. You want to do it. How can you go keto while honoring your own dietary bounds?
It depends on the restriction.Read More
Gaining mass and building strength while CrossFitting should be a breeze. You’re lifting heavy things using compound full-body movements like squats, deadlifts, and presses, providing a potent growth stimulus to your muscles. Yet, many people fall short of their goals, perhaps losing weight and improving performance but failing to really gain any real muscle or strength.
Today, I’m going to explain how going Primal can help you achieve both goals.
First, you must understand the very Primal reality of your body’s hormonal systems and their relation to the environment: Acknowledge that you are an organism whose endocrine system is acutely attuned to the inputs it receives. It’s actively engaged in the world around you, making predictions and taking actions based on your perceptions. If your body thinks it’s living through a famine, it will conserve energy and eliminate wasteful extravagances like big muscles and 2x body weight back squat. If your body thinks it’s living through plentiful times, it will be more liberal with energy and allow the growth of extracurricular tissues, like big muscles. Create an environment of abundance—or even the impression of one—and you will be more likely to gain muscle and strength.Read More
