Healthy Fats for Athletes: Benefits, Sources & Performance

---

Introduction

If carbohydrates are the most feared nutrient in the general population, fats might be the most misunderstood nutrient in sports nutrition.

I’ve worked with athletes who avoid fats almost completely because they’re worried about gaining weight.

I’ve also worked with athletes who swing to the opposite extreme and become convinced that eating more fat is the answer to better performance.

The truth usually lies somewhere in the middle.

Healthy fats play an important role in:

• hormone production
• nutrient absorption
• overall health
• long-term energy needs

At the same time, fats are often misunderstood when it comes to athletic performance.

Some athletes hear phrases like:

• “fat adapted”
• “keto athlete”
• “burn fat for fuel”

and assume that carbohydrates are no longer important.

Unfortunately, that’s rarely the case for athletes participating in high-intensity sports.

Volleyball players, CrossFit athletes, basketball players, soccer players, and most strength athletes still rely heavily on carbohydrates to support training and competition.

Healthy fats matter.

But they play a different role than carbohydrates and protein.

Within the M3 Performance Framework:

• Mind shapes beliefs and attitudes about fats
• Meals provide healthy fats as part of a balanced eating pattern
• Motion determines how the body uses fuel during activity

Understanding where fats fit can help athletes avoid common mistakes and build a nutrition strategy that supports both health and performance.

Why Healthy Fats Matter for Athletes

Many athletes think about nutrition through the lens of performance.

They want to know:

• What improves energy?
• What improves recovery?
• What helps build muscle?
• What helps them compete better?

Because fats don’t provide quick energy for intense exercise, they sometimes get overlooked.

That can be a mistake.

Healthy fats play several important roles that support both athletic performance and long-term health.

---

Hormone Production

One of the most important roles of dietary fat is supporting hormone production.

Hormones influence many aspects of athletic performance, including:

• recovery
• muscle adaptation
• energy levels
• mood
• overall health

Most athletes don’t think about hormone function until something starts feeling off.

Recovery slows down.

Energy drops.

Motivation decreases.

Training progress stalls.

While many factors contribute to these issues, chronically low fat intake can sometimes be part of the problem.

This is one reason why extremely low-fat diets are rarely recommended for athletes.

---

Nutrient Absorption

Certain vitamins require fat for proper absorption.

These include:

• Vitamin A
• Vitamin D
• Vitamin E
• Vitamin K

These nutrients help support:

• bone health
• immune function
• vision
• recovery

Without adequate dietary fat, the body may not absorb these nutrients as effectively.

---

Long-Term Energy

Unlike carbohydrates, which provide rapid energy during intense exercise, fats serve as a slower-burning fuel source.

The body stores far more energy as fat than it does as glycogen.

This makes fat an important energy source during:

• lower-intensity activity
• long-duration exercise
• everyday movement

However, it’s important to understand that this does not mean athletes should prioritize fats over carbohydrates.

Different fuels serve different purposes.

---

The M3 Fat Framework

Mind

Many athletes have strong opinions about fats.

Unfortunately, those opinions are often shaped by social media rather than science.

Common beliefs include:

• Fat makes you gain weight.
• Fat should be avoided.
• Carbohydrates are bad.
• High-fat diets improve all athletic performance.

These beliefs often create confusion.

The goal isn’t to fear fats.

The goal isn’t to overemphasize fats either.

The goal is understanding where fats fit within a balanced performance nutrition plan.

---

Meals

Healthy fats should be included regularly throughout the day.

Good examples include:

• avocado
• nuts
• seeds
• olive oil
• salmon
• nut butters

Fats help create meals that are:

• satisfying
• nutrient-dense
• supportive of overall health

At the same time, fats should complement carbohydrates and protein rather than replace them.

One of the biggest mistakes I see is athletes reducing carbohydrates dramatically while increasing fat intake.

For many athletes, this results in poorer training quality rather than better performance.

For more on athlete fueling, see:
👉 Carbohydrates and Athletic Performance

---

Motion

Exercise intensity matters.

The body does not use all fuels equally.

As exercise intensity increases, carbohydrate utilization generally increases as well.

This is why explosive sports such as:

• volleyball
• basketball
• soccer
• CrossFit
• sprinting

depend heavily on carbohydrate availability.

Healthy fats support overall health and provide energy during lower-intensity activities.

But when performance demands rapid energy production, carbohydrates remain the preferred fuel source.

Understanding this distinction is one of the most important concepts in sports nutrition.

---

The Science of Fat in Performance

Fats and Energy Systems

The body uses a combination of carbohydrates and fats to produce energy.

The exact mixture depends on exercise intensity.

During lower-intensity activities such as:

• walking
• easy cycling
• light aerobic exercise

the body relies more heavily on fat oxidation.

As intensity increases, the body gradually shifts toward greater carbohydrate use because carbohydrates can provide energy more rapidly.

This is one reason why athletes who participate in explosive, intermittent sports generally benefit from prioritizing carbohydrates rather than adopting extremely high-fat diets.

---

Hormonal Function

Healthy fats provide essential fatty acids that support numerous physiological functions.

These include hormone production related to:

• growth
• recovery
• reproduction
• overall health

Insufficient fat intake over time may contribute to disruptions in normal physiological processes, particularly when combined with inadequate overall energy intake.

This is one reason why low energy availability can negatively affect athlete health and performance.

---

Nutrient Absorption and Recovery

Fat-soluble vitamins depend on dietary fat for absorption.

Athletes who consistently consume extremely low-fat diets may unintentionally reduce their ability to absorb important nutrients that support:

• immune health
• bone health
• recovery
• long-term performance

---

How Much Fat Do Athletes Need?

One of the most common questions athletes ask is:

“How much fat should I be eating?”

The answer depends on:

• training volume
• body composition goals
• sport demands
• personal preferences

For most athletes, fats should provide approximately:

20–35% of total daily calories.

This range typically allows athletes to:

• support hormone production
• absorb fat-soluble vitamins
• maintain overall health
• still consume adequate carbohydrates for performance

The goal isn’t to eat as little fat as possible.

The goal also isn’t to load every meal with fat.

Balance matters.

For example, an athlete consuming 2,500 calories per day may obtain approximately:

• 55–97 grams of fat daily

while still leaving room for sufficient carbohydrate and protein intake.

Athletes who consistently consume extremely low-fat diets may struggle to meet their needs for essential fatty acids and overall health.

On the other hand, athletes who consume excessive amounts of fat sometimes unintentionally reduce carbohydrate intake, which may negatively affect training quality.

Best Sources of Healthy Fats

Not all fats are created equal.

While fats can fit into a healthy eating pattern, some sources provide more nutritional value than others.

---

Omega-3 Rich Foods

Omega-3 fatty acids are particularly important for overall health.

Good sources include:

• salmon
• sardines
• trout
• mackerel
• herring

These foods provide healthy fats while also supplying high-quality protein.

---

Plant-Based Fat Sources

Many athletes can obtain healthy fats from plant foods such as:

• avocado
• almonds
• walnuts
• pistachios
• chia seeds
• flax seeds
• hemp seeds

These foods also contribute:

• fiber
• vitamins
• minerals
• antioxidants

making them excellent additions to an athlete’s nutrition plan.

---

Healthy Cooking Fats

Examples include:

• extra virgin olive oil
• avocado oil

These can be used to prepare meals while supporting overall dietary quality.

---

Nut Butters

Nut butters can be useful for athletes who need:

• convenient calories
• portable snacks
• easy meal additions

Examples include:

• peanut butter
• almond butter
• cashew butter

However, portion awareness is still important because fats are calorie-dense.

---

Are Some Fat Sources Better Than Others?

Generally, yes.

Most athletes should aim to get the majority of their fat intake from nutrient-dense sources such as:

• fatty fish
• avocado
• nuts and seeds
• olive oil
• nut butters

These foods provide healthy fats along with vitamins, minerals, antioxidants, and other nutrients that support overall health.

Athletes do not need to completely avoid foods that contain saturated fat. Foods such as dairy products, eggs, and certain meats can still be part of a balanced eating pattern.

However, it may be beneficial to limit frequent intake of:

• trans fats
• heavily processed fried foods
• highly processed snack foods
• foods containing partially hydrogenated oils

The goal is not perfection.

The goal is building a nutrition pattern where most fat intake comes from high-quality food sources that support both health and performance.

---

When to Eat (and Avoid) Fats

Timing matters.

Not because fats are bad.

But because digestion matters.

---

Good Times to Eat Fats

Healthy fats fit well into:

• breakfast
• lunch
• dinner
• snacks

Examples:

Breakfast:
Eggs and avocado toast

Lunch:
Chicken salad with olive oil dressing

Dinner:
Salmon with vegetables and rice

Snack:
Apple with peanut butter

These meals provide fats while still supporting overall nutrition.

---

Times to Limit High-Fat Meals

Athletes often notice that very high-fat meals before training don’t sit well.

Meals that are heavy in:

• fried foods
• large amounts of cheese
• fast food
• large portions of fatty meats

may:

• slow digestion
• increase stomach discomfort
• leave athletes feeling sluggish

This becomes especially important before:

• practices
• games
• tournaments
• intense workouts

👉 Pre-Workout Nutrition for Athletes

---

Are Fats Bad for Athletes?

No.

Healthy fats are essential.

This is one of the biggest misconceptions I still encounter.

Athletes do not need to eliminate fats to:

• lose weight
• improve performance
• become leaner

In fact, removing fats completely often creates more problems than solutions.

The goal should be including appropriate amounts of healthy fats while maintaining adequate carbohydrate and protein intake.

---

Should Athletes Follow High-Fat Diets?

For most athletes participating in high-intensity sports, probably not.

High-fat diets may have specific applications in certain situations.

However, most athletes competing in sports requiring:

• speed
• power
• repeated sprint efforts
• explosive movements

benefit from prioritizing carbohydrates.

Examples include:

• volleyball
• basketball
• soccer
• CrossFit
• tennis
• strength training

These activities rely heavily on carbohydrate availability.

This doesn’t mean fats are bad.

It means fats and carbohydrates serve different roles.

For a deeper discussion:
👉 Carbohydrates and Athletic Performance

---

Can Eating Too Much Fat Hurt Performance?

Potentially, yes.

Not because fat itself is harmful.

But because excessive fat intake can sometimes displace nutrients that athletes need more urgently.

I’ve seen athletes unintentionally follow diets where:

• carbohydrates become extremely low
• fats become extremely high

The result often includes:

• lower training intensity
• poor recovery
• reduced energy
• decreased performance

Athletes generally perform best when fats support the nutrition plan rather than dominate it.

---

Sport-Specific Example: Volleyball

Imagine a beach volleyball player preparing for a long tournament day.

Breakfast includes:

• bacon
• sausage
• coffee

but very little carbohydrate.

The meal provides calories and fat.

However, it may not adequately support repeated high-intensity efforts throughout the day.

By early afternoon:

• energy levels may decline
• jumping performance may suffer
• fatigue may increase

A more balanced breakfast might include:

• eggs
• oatmeal
• fruit
• nut butter

This approach provides:

• carbohydrates for performance
• protein for recovery
• healthy fats for satiety and health

The goal isn’t avoiding fat.

The goal is creating balance.

Common Mistakes Athletes Make

Mistake #1: Avoiding Fats Completely

Some athletes still believe eating fat automatically leads to weight gain.

This often results in unnecessarily restrictive eating patterns.

---

Mistake #2: Following Extreme High-Fat Trends

Athletes sometimes assume more fat automatically equals better performance.

For most high-intensity sports, this isn’t supported by current evidence.

---

Mistake #3: Letting Fats Replace Carbohydrates

One of the biggest mistakes I see.

Carbohydrates and fats serve different functions.

Athletes need both.

---

Mistake #4: Eating Large High-Fat Meals Before Competition

This may increase digestive discomfort and reduce performance.

---

---

Action Steps

1. Aim for approximately 20–35% of daily calories from fat.
2. Include healthy fats regularly throughout the day.
3. Prioritize whole-food fat sources when possible.
4. Avoid very high-fat meals before intense training or competition.
5. Remember that carbohydrates remain the primary fuel source for high-intensity performance.
6. Focus on balance rather than extremes.

---

Conclusion

Healthy fats play an important role in athletic performance and overall health.

They support:

• hormone production
• nutrient absorption
• recovery
• long-term health

At the same time, healthy fats are not the primary fuel source for most high-intensity sports.

Athletes who avoid fats completely may compromise health.

Athletes who over-prioritize fats may compromise performance.

Within the M3 Performance Framework, healthy fats help support the system.

But balance between carbohydrates, protein, and fats is what ultimately drives long-term success.

Take the Next Step

Nutrition trends come and go.

One year athletes are told to avoid fats.

The next year they’re told to eat as much fat as possible.

The reality is that most athletes don’t need extreme approaches.

They need a nutrition strategy that supports training, recovery, health, and long-term performance.

Healthy fats play an important role in that strategy, but they work best when combined with adequate carbohydrates, protein, hydration, and consistent fueling habits.

If you’re unsure whether you’re eating the right balance of nutrients for your sport, training schedule, or body composition goals, a personalized sports nutrition plan can help remove the guesswork.

At M3 Total Wellness, I help athletes build evidence-based fueling strategies that support performance, recovery, and long-term success without relying on fad diets or restrictive approaches.

Whether you’re training for competition, trying to improve recovery, or simply looking to fuel more effectively, the goal is the same:

Fuel smarter. Recover better. Perform consistently.
