Does the Paleo diet really work for boosting athletic performance, or is it mostly a trend for people into fitness? The answer is a bit mixed. The Paleo diet centers around eating basic, natural foods that our ancient ancestors ate. This style of eating can be good for general health, but athletes have extra energy needs and sometimes need to adjust the diet to perform well and recover quickly.
The idea of a Paleo diet for athletes became popular with the 2005 book “The Paleo Diet for Athletes” by Dr. Loren Cordain and Joe Friel. They believed that even though we live in modern times, our bodies haven’t changed much since the Stone Age, so we’re better suited to traditional foods. This article explains how athletes can use the Paleo approach, the benefits, challenges, and practical ways to try it out.
What is the Paleo Diet for Athletes?
Basically, the Paleo diet for athletes means sticking to foods that humans once hunted or gathered-lean meats, fruits, vegetables, nuts, seeds-and staying away from foods that only came after farming started, such as grains, legumes, dairy, processed foods, or added sugar. Dr. Cordain’s research says these foods are what our bodies are best able to use, providing a solid base for health and energy.
The main difference for athletes is that their training and need for recovery are much higher than what people faced centuries ago. So, even though the basics of Paleo stay the same, athletes may need to make adjustments, especially around exercise times, to meet energy needs-often by adding more carbs than a normal Paleo diet might suggest.
How is the Paleo Diet Different from Other Athletic Diets?
Most athletic diets focus on lots of carbs-like bread, pasta, rice-and often include dairy and sports drinks for quick energy and protein. The Paleo diet leaves out grains, legumes, and dairy products. Instead, it relies on meat, fish, veggies, fruit, and healthy fats. Both diets value protein, but Paleo avoids dairy and bean-based protein powders.
Paleo foods are full of vitamins and minerals and may help reduce swelling and improve recovery by giving more nutrients and a better balance of fats, especially more omega-3s and fewer omega-6s, which helps the body heal and lowers inflammation.
Is Paleo Right for Every Athlete?
While the Paleo diet is healthy, not every athlete will find it fits their needs, especially those who do long or high-intensity sports. These sports need a lot of carbs, but strict Paleo has fewer easy-to-digest carbs to keep energy up. For example, runners or soccer players often need to refill muscle glycogen quickly.
However, athletes who focus on strength or short bursts of activity, or those training at lower levels, may find Paleo’s focus on protein and healthy fat works well for them. The key is adjusting the plan to fit the person, sometimes by adding more carbs from Paleo-friendly foods when needed.
What Foods are Allowed and Not Allowed on Paleo?

Macronutrient Needs for Athletes on Paleo
Athletes need to pay extra attention to how much protein, carbohydrates, and fat they eat, and when. Paleo is naturally high in protein and healthy fat, but athletes may need more carbs than a regular Paleo diet recommends, especially during heavy training.
Protein Needs and Sources
Protein helps build and repair muscles. Paleo athletes can get plenty from meats, fish, shellfish, and eggs, which are all rich in important amino acids like BCAAs that support muscle growth. Most athletes do well with about 1.2-2.0 grams of protein per kilogram of body weight each day.
Carbohydrate Planning and Timing
Carbs are the main energy source for hard workouts. Strict Paleo doesn’t allow usual carb sources like bread or pasta, so athletes need to eat more Paleo-friendly carbs like sweet potatoes, yams, pumpkin, winter squash, fruit, cassava, or tapioca.
Athletes might eat 50% of their calories from carbs during easier training phases and up to 60% or higher during tough or event-based periods. Eating the right carbs before, during, and after training-especially immediately after workouts-helps restore energy quickly and aids in recovery.
Healthy Fats
Fats provide long-lasting energy, are important for hormones, and help absorb vitamins. Paleo allows fats from good sources like animal fat, avocados, olives, coconut, and certain oils. Fats can make up 20-30% of an athlete’s calories, and this can change depending on training needs.
Nutrient Timing for Athletic Performance
When you eat is as important as what you eat for athletes. Getting the right nutrients before, during, and after workouts helps with energy, recovery, and muscle growth.
| Timing | What to Eat |
|---|---|
| Pre-Exercise | Low/moderate-GI carbs (e.g. sweet potatoes, fruit) 2+ hours before; 200-300 calories per hour before activity |
| During Exercise | High-GI fluids (diluted fruit juice, sports drink) for efforts over 1 hour; water for short sessions |
| Post-Exercise | Carbohydrate and protein in a 4-5:1 ratio within 30 minutes (e.g. banana, fruit juice, egg protein powder) |
| Long-term Recovery | Paleo carbs and protein for several hours after a tough session |
Benefits of Paleo for Athletes
- Supports muscle growth and strength-high in protein and BCAAs for rebuilding muscle
- May reduce inflammation-due to better fat balance and no processed foods
- Can improve body composition-more muscle, less fat
- Increases micronutrient intake-lots of vitamins and minerals from fruits and vegetables
Challenges and Risks for Athletes on Paleo
- Not enough carbs: Some sports need lots of carbs, but strict Paleo can make it hard to eat enough for top performance.
- Possible nutrient gaps: Cutting out dairy and some grains can leave athletes low in calcium, vitamin D, magnesium, or B vitamins unless they plan carefully.
- May need to adjust for sport: Endurance athletes need more carbs while strength athletes may need less, but both need to plan carb timing.
- Social or travel challenges: Eating out or traveling may make strict Paleo tough; being prepared with snacks and meal planning helps.
Tips for Athletes Using the Paleo Diet
- Plan meals and snacks ahead: Pre-cook protein and roast veggies, keep Paleo carbs ready, and pack snacks for travel or competitions.
- Pick the right supplements: Use Paleo-friendly protein powders (like egg white), omega-3s, or a simple multivitamin if needed.
- Stay hydrated: Carry water and add a pinch of sea salt if needed; use coconut water or fruit for electrolytes during long sessions.
- Listen to your body: Tiredness, poor recovery, illness, or trouble gaining muscle might mean you need to eat more, add carbs, or ease up on strict rules.
- Be flexible: Sometimes, it’s ok to eat outside strict Paleo for recovery or social events-what matters is the overall pattern.
What Does the Research Say?
Research on Paleo and athletics is growing. Some studies show better body composition (more muscle, less fat) and improved metabolic markers (like blood sugar and cholesterol). Most of the benefits seem linked to cutting out junk, processed foods, and eating more nutrient-rich whole foods, rather than something unique to Paleo.
Some experts point out that Paleo’s low-carb approach isn’t perfect for every athlete, especially during heavy training. It can work well during lighter phases or off-season, with athletes allowing more carbs from all sources, or even some non-Paleo foods after hard workouts.
Final Advice for Athletes on Paleo
Following the Paleo diet as an athlete means figuring out what works best for your body and your sport. It’s about using good nutrition to feel and perform your best, not just following rules. There will be times, especially around hard training sessions or competitions, when you should add more carbs, even if they aren’t strictly Paleo.
Watch for any signs you need to change your approach, and don’t be afraid to tweak your plan or ask a sports nutritionist for help. The Paleo diet can be a great tool for athletes-if you make it work for you and your needs.
