AIP for Athletes: Fueling Performance Without Grains, Dairy, or Eggs

Nov 20, 2025

When most people think about athletic nutrition, they picture protein shakes packed with whey, bowls of oatmeal dripping with honey, and post-workout recovery meals centered around eggs and toast. So when you're an athlete who's committed to the Autoimmune Protocol, it can feel like you're being asked to compete with one hand tied behind your back. We get it. As someone who's been both an athlete and an AIP advocate (our co-founder Heather played Division 1 basketball and managed Psoriatic Arthritis through AIP), we know firsthand that fueling performance without grains, dairy, or eggs isn't just possible. It's actually a game changer.

The truth is, your body doesn't need those conventional athletic staples to perform at its best. What it needs is quality fuel that reduces inflammation, supports gut health, and provides sustained energy without triggering autoimmune responses. Let's talk about how to make that happen.

Understanding Energy on AIP

Here's something that surprises a lot of athletes when they first start AIP: you don't need to go low carb. In fact, going too low on carbohydrates can actually tank your performance, mess with your sleep, and leave you feeling pretty terrible. The AIP is not a ketogenic diet, and for good reason. Insulin plays crucial roles beyond just managing blood sugar, including supporting thyroid function, modulating your immune system, and helping your muscles recover after hard training sessions.

What you do need is the right kind of carbohydrates. We're talking about nutrient dense, anti-inflammatory sources like sweet potatoes, plantains, winter squash, and fruits. These foods provide the glucose your muscles need to perform without the gut-irritating effects of grains or the inflammatory triggers that might be setting off your autoimmune symptoms. Think of them as premium fuel instead of the cheap stuff that gunks up your engine.

For most athletes on AIP, carbohydrate needs will vary based on your training load. If you're doing high intensity endurance work like running, cycling, or swimming, you'll need more carbohydrates to replenish muscle glycogen than someone doing lower intensity activities or strength training. A good rule of thumb is to include a serving of starchy vegetables or fruit with each meal, and adjust based on how you feel during your workouts. Need help finding the best AIP carbohydrate sources?

Pre-Workout Nutrition That Works

The pre-workout meal can make or break your training session, and on AIP, you've got plenty of options that'll set you up for success. The key is timing and composition. You want easily digestible carbohydrates paired with a moderate amount of protein and minimal fat, consumed about one to three hours before you train.

Some of our favorite pre-workout meals include a sweet potato topped with leftover chicken and a drizzle of coconut oil, a smoothie made with frozen berries and collagen powder blended with coconut milk, or some plantain chips with compliant jerky. If you're eating closer to workout time, stick with something lighter like a banana or some dried fruit. The goal is to top off your glycogen stores without feeling weighed down or dealing with digestive distress mid-workout.

Here's where having convenient AIP-friendly options really matters. We designed our baking mixes specifically for people who need quick, compliant fuel without spending hours in the kitchen. A batch of our muffins made ahead of time can be perfect pre-workout fuel. They provide the carbohydrates you need, they're easy to digest, and they won't trigger inflammation that could compromise your performance.

Protein Strategies for Muscle Building

Let's address the elephant in the room. Yes, you can absolutely build and maintain muscle on AIP, even without eggs, dairy, or legumes. The secret is prioritizing high quality animal proteins throughout the day and making sure you're getting enough of them.

Research consistently shows that consuming protein evenly throughout the day is more effective for muscle protein synthesis than loading it all into one meal. Aim for about 20 to 40 grams of protein per meal, depending on your body size and training intensity. This might look like a palm-sized portion of grass-fed beef, wild-caught salmon, pastured chicken, or even organ meats if you're feeling adventurous.

For athletes, collagen and gelatin can be valuable additions to your protein intake. While they don't contain all the essential amino acids needed for muscle building on their own, they support joint health, gut healing, and connective tissue repair. This is especially important when you're putting stress on your body through training. Bone broth is another AIP staple that provides protein along with minerals and compounds that support recovery.

Don't be afraid to eat more protein than the standard recommendations suggest. Active individuals, especially those doing strength training or high volume endurance work, often need closer to 0.7 to 1 gram of protein per pound of body weight daily to support optimal recovery and adaptation.

Recovery: Where the Magic Happens

Here's something every athlete needs to understand: you don't get stronger during your workout. You get stronger during recovery. And recovery nutrition on AIP can be incredibly effective when you do it right.

The post-workout window is real, though it's wider than we once thought. Within two to four hours after training, your muscles are primed to absorb nutrients and kickstart the repair process. This is when you want a combination of protein and carbohydrates. The carbohydrates replenish glycogen stores that got depleted during your workout, while protein provides the amino acids needed for muscle repair and growth.

A recovery meal might include grilled salmon with roasted root vegetables and a side of sauteed greens, a bowl of compliant chili made with ground beef and sweet potato, or even a smoothie with collagen, frozen fruit, and sweet potato blended in (trust us, it's better than it sounds). If you're training multiple times per day or doing two-a-days, timing becomes even more critical, and you'll want to prioritize that post-workout nutrition within the first hour.

Hydration and electrolytes matter too, especially on AIP where you're not consuming processed foods that are typically loaded with sodium. Make sure you're drinking adequate water and consider adding a pinch of high quality sea salt to your water or meals to replace what you lose through sweat.

Managing Energy Throughout Training Cycles

One thing we've learned from working with active individuals on AIP is that energy needs aren't static. During heavy training blocks, you'll need more fuel than during recovery or off-season periods. Listen to your body. If you're feeling constantly fatigued, struggling to complete workouts that used to feel manageable, or noticing that your recovery is taking longer than usual, you probably need to eat more, particularly more carbohydrates. If you're new to AIP and finding the transition challenging, our guide on transitioning smoothly to a restorative diet can help.

Some athletes find that strategic timing of their higher carbohydrate meals around training sessions works well. Others do better with consistent carbohydrate intake throughout the day. There's no single perfect approach, and you'll need to experiment to find what works best for your body, your autoimmune condition, and your training demands.

Making It Sustainable

The biggest challenge for athletes on AIP isn't the nutritional science. It's the practical reality of preparing compliant meals when you're training hard, working full time, and trying to have a life. This is exactly why we created Eat Gangster. We wanted to make it possible for people on restrictive diets to still enjoy the foods that make life feel normal, whether that's grabbing a muffin before your morning run or having a treat after a tough workout that doesn't derail your healing journey.

Being an athlete on AIP requires more planning than following a standard sports nutrition protocol, but it absolutely doesn't mean sacrificing performance. In fact, many athletes find that once they've eliminated their inflammatory triggers and their gut has healed, they actually perform better than they ever did eating the standard athletic diet. Less inflammation means better recovery. Better recovery means more consistent training. More consistent training means better results.

Your athletic goals and your autoimmune health don't have to be at odds. With the right fuel, proper timing, and a bit of planning, you can absolutely crush your training on AIP. And when you need something quick, compliant, and actually delicious to support your active lifestyle, we've got your back with our baking mixes that make fueling performance a whole lot easier.
