The Health, Science & Technology Podcast Episode 2: Fueling Fitness: The Fascinating Science behind Pemmican

Executive Summary

Daily road cycling demands a lot from my body, and I've found that optimizing physical fitness directly boosts my performance as an alto saxophonist and my capacity to manage my IT business. Because the body acts as the engine powering this work, I've spent a lot of time recently researching how to fuel it correctly.

Since I increased my daily mileage, my appetite and hunger have grown considerably. The leg muscles are the strongest in the human body, and pushing a bicycle for miles burns through calories rapidly. I wanted to look beyond typical processed snacks and identify a high-quality fuel source that supports long-term health. This search led me to pemmican, a traditional preparation developed by Native Americans. In this episode, I explain the science behind why pemmican functions as a survival food and how modern athletes can interpret the principles behind this historical fuel.

A. The Origin of Pemmican

If you found yourself on the North American Plains five thousand years ago, you'd quickly realize that the hardest part of surviving wasn't just finding food. The challenge was managing energy so that you could make it through harsh winters when fresh game vanished. Long before modern refrigeration, Indigenous nations such as the Cree and Lakota solved this problem with a sophisticated understanding of food chemistry. They developed pemmican, a term derived from the Cree word pimîhkâ, which means manufactured grease.

The core problems faced were portability and preservation. Fresh meat is heavy because it consists of about 75 percent water, and it spoils within days of a hunt. To solve this, these nations engineered a rigorous, multi-stage process to create a shelf-stable ration. First, they sliced lean meat from bison, elk, or deer into thin strips and dried them until the moisture content dropped below 20 percent. By stripping away that water, they eliminated the primary factor that allows bacteria to grow. Once the meat was bone-dry, they pounded it into a fine, fibrous powder.

The final step was the most crucial. They mixed the dried meat with rendered animal fat, specifically suet or bone marrow. By saturating the protein with these fats, they created a moisture-proof seal that protected the meat from oxidation and the outside environment. The result was a caloric powerhouse, packing roughly 3,800 calories into a single pound. This allowed hunting parties to carry months of nutrition in a simple leather bag. It was a logistical breakthrough that enabled the massive trade economies of the Métis and other nations, who could produce and transport up to one million pounds of this fuel in a single hunt. They turned a perishable resource into a permanent energy reserve, making life possible in conditions that would've otherwise been unmanageable.

B. What Modern Cyclists and Other Athletes Can Learn From Pemmican's Science

When you look at the physical demands of daily road cycling, the science behind pemmican offers deep insights into metabolic efficiency. Modern sports nutrition often emphasizes heavy carbohydrate loading, but the Indigenous model of pemmican teaches us the benefits of fat oxidation. By relying on a combination of dense protein and lipids, this traditional food provides a steady energy release that avoids the sharp glucose spikes and crashes associated with high-sugar energy gels. For an athlete, this creates a stable fuel source that maintains power through long rides without the constant, frantic need for refueling.

The true genius of pemmican lies in its nutrient density relative to its weight. In cycling, where every ounce on the bike or in your jersey pocket matters, the ability to carry thousands of calories in a small, durable package is practical. Because it's essentially a concentrated form of bioavailable fat and protein, it provides the building blocks for muscle repair and endurance in a form the human digestive system processes efficiently.

You can apply these principles by swapping out high-sugar gels for snacks that prioritize stable fats and proteins, such as beef jerky, nuts, or tallow-based energy bites. Shifting toward fat oxidation helps to stabilize an athlete's insulin response, which prevents the mid-ride energy dips that plague many endurance athletes. Note that your metabolism requires a period of adaptation if you're transitioning from a carb-heavy diet, so you should test these changes incrementally during shorter rides. Because fat is a more concentrated energy store than glycogen, your body can tap into these reserves more effectively, delaying fatigue and extending your overall endurance. By testing these high-fat, high-protein alternatives, you can train your metabolism to run on a long-burning fuel source that supports the sustained energy required for demanding days on the road and in the studio.

C. Considerations for Pemmican Preparation and Quality

Making safe and effective pemmican mainly depends on technical precision. The most important step is removing every bit of moisture from the meat. Because even a tiny amount of water allows bacteria to thrive, one must dry lean meat, such as bison, venison, or beef, until it's brittle and snaps like glass. If one leaves even a little moisture inside, it'll ruin the bond between the fat and the meat, and the batch will spoil quickly.

The choice of fat is as important as the drying process. Pemmican requires rendered fat, like suet or marrow, because these fats are highly saturated and don't go rancid easily. Rendering is simply heating the fat slowly until the water evaporates and the bits of tissue settle out, leaving you with a clean, golden oil. When you mix this warm fat with your powdered, dried meat, it needs to coat every single fiber completely, creating an airtight seal that locks out oxygen. If one doesn't use enough fat, it'll leave air pockets, and the meat will oxidize and turn rancid.

If you're making pemmican to fuel your training, the quality of your ingredients dictates the result. Grass fed or wild game meats provide a much better fatty acid profile than conventional options. If you decide to add dried berries for flavor or extra energy, you must dry them until they're just as hard as the meat. Adding soft or store bought dried fruit introduces hidden moisture that'll destabilize the entire mixture. If you follow these steps carefully, you'll end up with a shelf stable, energy dense fuel that stays fresh at room temperature for a long time, giving you a reliable source of energy for your hardest rides.

While preparing pemmican yourself offers the best control over quality and ingredients, you can find professionally made options on the market today. Several companies specialize in traditional pemmican production, catering to the survivalist and endurance athlete communities. When purchasing these products, prioritize brands that explicitly state their ingredient sourcing, such as the use of grass fed or wild game meat, and check for the absence of modern additives or preservatives. High quality commercial pemmican should maintain the traditional ratio of fat to protein, providing the same nutrient density that allowed historical hunting parties to sustain themselves over long distances.
