It’s not about how much you eat, but how well your body utilizes stored energy. As an athlete, I once believed I needed heaps of protein, carbs, and fat every day to fuel my performance. But by developing metabolic flexibility, I’ve learned that my body can thrive on stored fat alone when I skip meals. By restricting carbs and lowering insulin (and choosing the right kinds of workouts), I’ve optimized enzyme function and preserved muscle mass, even during extended periods of fasting. It’s incred

When it comes to longevity, focus on healthy fats as a key energy source—think avocados, olive oil, and the natural fats in salmon, steak, and other meats. The fear of saturated fat is unfounded; in moderation, fats from macadamia nuts and coconut are beneficial. Prioritize protein first, healthy fats second, and round it out with nutrient-rich carbs such as berries. This combo fuels your body for the long haul. | Mark Sisson

One of my go-to workouts is a 60-second rope pull—full intensity, as fast as you can. It’s brutal, but it’s over in a minute. After a short rest, I repeat it four times and that’s my workout for the day. But fitness isn’t just about pushing limits; it’s about having fun too. Whether I’m paddleboarding with dolphins or riding a fat bike in the sand with my wife, I make sure to enjoy the process. Play and fun are essential parts of my routine, not just regimented workouts. | Mark Sisson

Fat is not just a source of calories; it’s essential for vital bodily functions such as creating cell membranes, facilitating cell communication, and acting as precursors to hormones. A certain level of body fat is crucial for maintaining health. The outdated notion that “fat makes you fat” has been debunked, yet it persists in some medical circles despite clear research indicating the need for fats in our diet. Eliminating fats leads to a diet overly dependent on carbohydrates and protein. Carb

When I shop for food, I head straight to the meat counter. My go-to? A pasture-raised New York strip. That’s the cut that consistently delivers for me. Here’s what I look for: animal welfare standards, no hormones, no antibiotics, and great marbling for flavor. While every steak is grass-fed for most of its life, I don’t shy away from grain-finished cuts—they taste better, and the difference in fatty acid profiles is negligible. Let’s be honest, you’re not buying steak for omega-3s; it’s about t

Endurance athletes learn to manage discomfort through consistent training, often in solitude. Unlike other sports where training is mostly fun, endurance sports focus on resilience—pushing through tough moments and embedding a mindset that differentiates between discomfort that is simply challenging and that which is insurmountable. The key lies in understanding that most discomforts can, indeed, be overcome. Having said all that, not everyone is cut out to be an endurance athlete, and there are
