Why are fats important for athletes?

Fats play a crucial role in many of your body’s processes that affect athletic performance and health. Some of the benefits showing the importance of fats for athletes are:

Energy production

Fats are the primary fuel for light to moderate intensity exercise. During prolonged lower intensity exercise, fats can provide more than twice the amount of energy per gram (9 calories per gram)  than carbohydrates or protein, which each provide 4 calories per gram, and can spare muscle glycogen

Additionally, fats can help maintain blood glucose levels, help you feel full and prevent hypoglycemia, which can impact cognitive and motor skills.

Hormone production

Fats are essential for the production of some hormones that regulate metabolism, muscle growth and recovery. They help control cortisol, a stress hormone that can increase muscle breakdown and inflammation.

Organ protection

Fats act as a cushion for your organs such as the heart, lungs and kidneys protecting them from injury. Your body relies on fats to help regulate body temperature and prevent heat loss, which can affect performance and health in cold environments.

Vitamin absorption

Fats help absorb fat-soluble vitamins, such as vitamin A, D, E, and K, which support various functions, such as vision, bone health, immune system and blood clotting. 

They also enhance the bioavailability of antioxidants, such as carotenoids and polyphenols, which can reduce oxidative stress and inflammation.

How much fat do athletes need?

There is no one-size-fits-all recommendation, but generally athletes should be between 20-35% of your total calorie intake. 

The amount of fat that athletes need depends on several factors, such as their body composition, training intensity, duration and goals. For example, an athlete gearing up for a long distance run or intense two a day practices may need more carbohydrates in their meals for loading energy stores.

Best type of fats for athletes

Not all fats are created equal. Some fats have health benefits, while others should be eaten less frequently. Here is a brief overview of the different types of fats so you can understand the importance of fats for athletes and their effects on health and performance :

Saturated fats

Saturated fats are in animal products such as meat, dairy and egg and some plant oils such as coconut and palm oil. They are solid at room temperature and have a high melting point.

You should consume saturated fats in moderation, since they can raise blood cholesterol levels and increase the risk of cardiovascular disease. 

Athletes should limit their saturated fat intake to less than 10% of their total calories.

Monounsaturated fats

Monounsaturated fats are in plant oils such as olive, canola and peanut oil and nuts, seeds, and avocados. They are liquid at room temperature and have a lower melting point than saturated fats. 

Monounsaturated fats have the most health benefits and are the healthiest type of fat, because they can lower blood cholesterol levels, improve insulin sensitivity and reduce inflammation. 

Athletes should aim for 10-15% of their total calories from monounsaturated fats.

Polyunsaturated fats

Polyunsaturated fats are in plant oils such as soybean, corn and sunflower oil and fish, and seafood. They are liquid at room temperature and have the lowest melting point of all fats. 

Polyunsaturated fats are essential for the body because they provide omega-3 and omega-6 fatty acids, which support your brain function, immune system and blood clotting. 

These types of fats are called essential because your body needs them to function, but cannot make them, so you need to get them from foods. (1)

Athletes should aim for 5-10% of their total calories from polyunsaturated fats, with a ratio of omega-3 to omega-6 of 1:4 or less. (2)

Trans fats

Trans fats are created by adding hydrogen to unsaturated fats, making them more solid and stable. They are in processed foods such as margarine, baked goods, and fried foods and some animal products such as dairy and meats. 

Trans fats are the worst type of fat, as they can raise blood cholesterol levels and increase inflammation. Athletes should try to minimize the among of trans fats since they have no nutritional value and can impact health and  performance.

Sources of dietary fats

Here are some examples of the types of dietary fats and the foods you can find them.

Fat typeFood source
Saturated fatsbutter, cheese, cream, bacon, sausage, beef, pork, chicken skin, coconut oil, palm oil
Monounsaturated fatsolive oil, canola oil, peanut oil, avocado, almonds, cashews, peanuts, sesame seeds
Polyunsaturated fatssoybean oil, corn oil, sunflower oil, flaxseed oil, fish oil, salmon, tuna, mackerel, walnuts, chia seeds, flax seeds
Trans fatsmargarine, baked goods, fried foods, some dairy and meat products

Impact of a high fat diet

A diet high in fat can lead to inflammation which can impact your blood vessels. (3) This could affect your performance as well as your ability to focus. (4). 

Other impacts from a high fat diet include:

  • Chronic exhaustion
  • Irritability
  • Restlessness
  • Body fat percentage increases
  • Muscle tissue decreases
  • Increased potential for GI distress during physical activity such as nausea, diarrhea, vomiting
  • Increased risk for heart disease

A diet high in fat and low in carbohydrates slows the process of energy storage for muscles. Therefore you may have less fuel stored when it’s needed most for high intensity activities like an intense soccer match.

How to incorporate fats into your diet

Fats are an important part of a balanced diet, but you should focus on those with health benefits and limit those that less healthy. Here are some tips on how to incorporate fats into your diet as an athlete :

  • Choose lean cuts of meat, skinless poultry, and low-fat dairy products to limit your saturated fat intake.
  • Use plant oils such as olive, canola, or peanut oil for cooking and salad dressings and avoid deep-frying or using butter or lard.
  • Eat fatty fish such as salmon, tuna or mackerel at least twice a week to get enough omega-3 fatty acids
  • Snack on nuts, seeds, and avocados, which are rich in monounsaturated fats and other nutrients, such as protein, fiber, and antioxidants.
  • Read food labels and avoid foods that contain trans fats, hydrogenated oils or partially hydrogenated oils.
  • Balance your fat intake with your carbohydrate and protein intake and adjust your portions according to your energy needs and goals.

Lower your saturated fat intake

  • Choose foods that are steamed, baked, grilled, broiled, baked, poached and mashed
  • Use sparingly saturated fats such as butter and margarine
  • Avoid foods that are fried, breaded, crispy, sautéed 

When is the best time to eat fats?

The best time to eat fats depends on several factors, such as the type of fat, the type of exercise and activity you’ll be doing and your individual needs. However, some general tips are:

  • Avoid eating high-fat meals or snacks before, during or immediately after a workout or a game, as they can slow down digestion, cause stomach discomfort and interfere with the absorption of carbohydrates and protein, which are needed for energy and recovery.
  • Eat fats earlier in the day, preferably at breakfast or mid-morning, as they can provide a steady source of energy, keep you satiated, and help avoid cravings later in the day.
  • Eat healthy fats in moderation throughout the day, balancing them with carbohydrates and protein, and adjusting your portions according to your energy needs and goals. Fats can help you feel fuller for longer, which can prevent overeating and support weight management.

Final thoughts

Fats are a vital component of an athlete’s diet. They provide energy, support hormone production, protect vital organs, and help absorb fat-soluble vitamins.

However, not all fats are equal, and you should choose the right types and amounts of fats to optimize your health and performance.

Make sure to incorporate healthy fats into your overall balanced meals plan.
