What Is The Runner’s Diet?

The runner’s diet focuses on a balanced diet of carbohydrates, proteins, healthy fats, and essential minerals and vitamins. Proper nutrition provides the required energy to fuel runs and recuperate from training. The runner’s diet can also enhance endurance, avoid injury, and promote muscle growth and repair (1).

One may get on different types of runners’ diets depending on their specific needs and goals. Some of these include:

1. High-Carbohydrate Diet

Consuming lots of carbohydrates to power runs and refuel afterward. Beneficial for endurance runners or those who participate in long-distance running events.

2. Low-Carbohydrate Diet

Consuming fewer carbohydrates while consuming more healthy fats and proteins. Beneficial for those looking to lose weight and improve body composition.

3. Low-Fat Diet

A lower fat and higher intake of carbohydrates and protein. Beneficial for anyone trying to get healthier and lose weight.

4. High-Fat Diet

A high intake of healthy fats that is beneficial for runners looking to reduce inflammation and improve their overall health.

5. Vegetarian/Vegan Diet

Eliminates meat and other animal products for plant-based protein sources, carbs, and lipids.

6. Gluten-Free Diet

Cuts out wheat, barley, rye, and products containing gluten.

Dietary requirements for runners may differ depending on their body composition, training regimen, level of intensity, and personal food preferences. However, the science behind it remains the same. Scroll down for additional information on this diet and how it works.

How Does The Runner’s Diet Work?

A runner’s diet should be a healthy balance of carbohydrates, protein, healthy fats, vitamins and minerals, and would comprise fruits, vegetables, and whole grains. Drinking enough water and electrolyte-rich fluids is essential for runners to stay hydrated.

Carbohydrates

The majority of a runner’s diet should consist of carbohydrates because they are the main energy source for running.

Studies indicate that carbohydrate ‘loading’ may improve marathon performance by enabling the runner to maintain their preferred pace for more time before becoming fatigued. This can be achieved by reducing exercise days before the marathon and consuming 10-12 g/kg of carbohydrates daily in the 48-hour period before the event (2).

Excellent sources of carbohydrates include whole grains, fruits, vegetables, and legumes. These foods give runners the energy to finish their training and aid in replenishing muscle glycogen stores (3).

Did You Know?The human body can run up to 25 miles per hour. However, the average running speed for most people is around 8 miles per hour.

Protein

Protein is pivotal for runners because it supports the recovery and regrowth of muscle tissue damaged during exercise (4). Studies suggest that endurance athletes’ recommended daily protein intake may be between 1.2 and 2.0 g/kg (5).

Marathon runners who had a carbohydrate and protein mix during a run experienced less weariness and muscle pain 72 hours later than those who only consumed carbohydrates. This indicates that proteins play a role in post-run muscle recovery (6).

Lean meats, fish, eggs, dairy products, beans, lentils, and quinoa are excellent protein sources for runners.

Healthy Fats

Runners should have a reasonable amount of healthy fats in addition to carbohydrates, protein, and other macronutrients. Fat intake of about 30% of daily calories is advised for athletes. However, those looking to shed body fat may consume 0.51g/kg/day of dietary fat (7).

Studies suggest that runners who follow a low-fat diet take in fewer calories and perform less efficiently on endurance tests than those who follow a medium- or high-fat diet (8). Thus, consumption of good fats is imperative for marathon runners.

These include the monounsaturated and polyunsaturated fats in foods like olive oil, nuts, seeds, and avocado (9).

Vitamins And Minerals

Vitamins and minerals like iron and calcium are essential for runners as they deliver oxygen to cells and boost bone health, respectively (10), (11).

However, chronic vitamin and/or mineral supplementation does not improve exercise performance (12). Obtain your daily requirements from your diet alone rather than concentrating solely on multivitamins or mineral supplements. Whole grains, nuts, seeds, fruits, and vegetables are excellent sources of vitamins and minerals.

Hydration

Drinking enough water is critical to helping you perform better, recover more quickly, and avoid injuries (13). Runners should try to drink lots of water and electrolyte-rich beverages throughout the day, but should focus on doing so before, during, and after exercise.

If your objective is to lose extra weight while running, you can achieve it by subtly altering your diet. Scroll down to learn more about it.

Runner’s Diet For Weight Loss

A runner’s diet can work for weight loss by creating a calorie deficit, which occurs when the body burns more calories than it consumes. Running and other forms of exercise can increase energy expenditure while lowering overall calorie intake (14).

Running enthusiasts should consume nutrient-dense foods while reducing processed foods and added sugars to aid in weight loss (15), (16). By doing so, they are consuming the right nutrients to sustain their running while also consuming fewer calories overall.

Runners should also be mindful of the timing and portion size of their carb intake to avoid overeating. Running more frequently and intensely can help burn more calories and establish a calorie deficit to aid in weight loss. However, this should be done gradually and under the guidance of a coach or physician to avoid injury.

Aside from better weight management, this diet also offers other health advantages. Learn them in the next section.

Benefits Of The Runner’s Diet

1. May Help Reduce Inflammation

Adequate intake of healthy fats found in nuts, seeds, and olive oil can help reduce inflammation in the body (9). Inflammation can lead to injury and delay recovery, so reducing it can help runners recover faster and perform better (17), (18).

Animal studies suggest that extra virgin olive oil can improve physical activity-inducedoxidative stressⁱ  XA condition caused by an imbalance between the creation and buildup of oxygen radicals in muscles and the ability to detoxify them. and inflammation (19). In a study, healthy adults who took omega-3 supplements after eccentric arm curl exercise experienced reduced inflammation (20).

2. May Boost Overall Health

Consuming a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats can support overall health and reduce the risk of chronic diseases. Studies have linked healthy eating habits to a moderately lower incidence of type 2 diabetesⁱ  XA long-term condition where your body produces or uses insulin inefficiently, leading to high blood sugar levels. , fractures, and colorectal and breast cancers. A weak correlation between a healthy diet and cardiovascular mortality and respiratory disorders was also discovered (21).

3. May Boost Mental Health

Adequate nutrition can improve mood and cognitive function, which can help runners perform and feel better overall.

Studies suggest that diets rich in omega-3 fatty acids and low in saturated fats lower the risk of stress-related psychiatric issues (22). Both the Mediterranean diet and the runner’s diet encourage the consumption of fruits, nuts, vegetables, and fish. A study found that the Mediterranean diet is healthier for mental health than the Western diet, which is often characterized by “unhealthy” eating habits (23). Thus, maintaining a healthy, specialized diet for runners may improve their mental health.

StyleCraze SaysElectrolyte-rich drinks are supposed to complement water rather than replace it. These replenish the electrolytes lost through sweating.

The time and quantity of your meals significantly impact how well you run. Check out in the next section what you need to eat at the various run stages.

 Before You Run

 It’s essential to provide proper nutrition needed for the run and to stay away from fatty or heavy foods that may upset your stomach. Here are some recommendations for pre-run meals and snacks:

• 2-4 Hours Before A Run: Eat a balanced meal that contains carbohydrates, protein, and healthy fats.
• 1-2 Hours Before A Run: Eat a simple, light snack like a banana, granola bar, or a small yogurt dish if you are feeling hungry.
• 30 Minutes To 1 Hour Before A Run: Consume a small amount of easily digestible carbohydrates like a sports drink, an energy gel, or a piece of fruit.

During A Run

Refilling your body’s energy reserves is essential throughout a run to retain performance and avoid weariness. You might need to consume carbs and electrolytes while running, depending on the length and difficulty of the run. Following are some options for fuelling up while running:

• Sports Drinks: Formulated to provide carbohydrates and electrolytes to help maintain hydration and blood sugar levels during prolonged exercise.
• Energy Gels: Concentrated sources of carbohydrates like glucose, maltodextrin, or fructose. They are easy to carry and consume during a run and provide a quick energy boost.
• Energy Chews: Similar to energy gels but in a chewable form, they usually contain a mix of carbohydrates and electrolytes.
• Fruit or Candy: Natural foods like bananas, dried fruits, or sports candies that are high in carbohydrates and easy to consume on a run.

After A Run

Eating the right foods after a run is crucial for the recovery, repair, and replenishment of energy stores. Here are some guidelines for post-run meals and snacks:

• Within 30 Minutes After A Run:  Eat a snack or meal containing a mix of carbohydrates and protein. You can have recovery bars, protein shakes, or healthy smoothies.
• Within 2 Hours After A Run: Have a balanced meal that contains carbohydrates, protein, and healthy fats. Opt for recipes that include Greek yogurt with oatmeal, granola, or fruits like berries. You can also incorporate lean meats like tuna, chicken, or salmon.

The amount of fluids you need to consume before, during, and after a run depends on your body weight, length and difficulty of the run, temperature and humidity, and your requirements. The following guidelines are recommended by the National Athletic Trainers’ Association (NATA) (13):

• Before a run: Drink about 500 to 600 ml of water or a sports drink 2-3 hours before your run and an additional 200 to 300 ml of fluids 10-20 minutes before your run.
• During a run: Fluid replacement during the workout should match sweat and urine losses. Retain hydration level that limits body weight loss to under 2%, which is accomplished by consuming 200 to 300 ml of fluids every 10-20 minutes.
• After a run: Hydration after exercise should compensate for any fluid lost during training or competition. You can weigh yourself before and after the run to know how much water you need to drink.

StyleCraze SaysEven if you don’t feel thirsty, drink water frequently because thirst is not always a reliable indicator of hydration. If it’s hot and humid outside, drink about 100 – 200 ml of water every 15 minutes to stay hydrated.

Who Should Not Follow The Runner’s Diet Plan

Certain runners should ensure that their diet is safe and provides all the necessary nutrients to support running. The diet should support recovery and not interfere with the medications they take. These include individuals who:

• Have food allergies or sensitivities
• Have a particular medical condition like diabetes (31)
• Have eating disorders (32)
• Pregnant or breastfeeding women (33)
• Individuals on medications like warfarin and antibiotics (34)

Every runner has distinct needs and goals and should customize their diet to meet them. The general public should also be informed of the possible drawbacks of adhering to a runner’s diet.

Side Effects Of The Runner’s Diet

You may experience the following side effects while on a runner’s diet:

• Rapid Weight Loss

Anecdotal evidence suggests that runners consuming low-calorie foods or not getting enough carbohydrates may experience rapid weight loss. This may result in exhaustion, injury, and poor performance. However, further research is warranted in this regard.

• Nutrient Deficiencies

A very restrictive diet or eliminating entire food groups can lead to nutritional deficiencies. This may lead to unhealthy eating habits and a poor relationship with food (35).

• Gastrointestinal Distress

Consuming excess high-fiber foods might result in bloating, gas, and diarrhea (36).

• Dehydration

Little or excessive consumption of diureticⁱ  XAny ingredient, substance, or drug that encourages diuresis (excessive urine production) to flush out salt and water. fluids (coffee, tea, alcohol) can lead to dehydration, which can negatively impact performance and recovery (37).

Remember that eating a healthy, varied diet may prevent these adverse effects. Advice from a nutritionist or an experienced dietitian can ensure that a runner’s diet is well-balanced, supports their training, and prevents these possible side effects.

The Final Word

Diet and lifestyle are essential to a runner’s training and results. It’s crucial to consume a balanced diet and plenty of water to power your runs. However, a runner’s diet should be customized to meet their unique demands and goals. Remember, no two people are the same when it comes to weight loss. So, it is imperative to speak with a registered dietitian or a doctor to develop a personalized plan that addresses your needs and health objectives.
