Intermittent Fasting for runners
Intermittent fasting has become increasingly popular in recent years as a way to improve health, lose weight, and even enhance athletic performance. As a runner, incorporating intermittent fasting into your training routine can provide numerous benefits, but it is important to consider the type of running you are doing, such as 5K or marathon training, as well as the potential risks.
Intermittent fasting involves alternating periods of eating and fasting. There are several different methods of intermittent fasting, including the 16/8 method, where you fast for 16 hours and eat within an 8-hour window each day, and the 5:2 method, where you eat normally for five days and restrict calorie intake to 500-600 calories for two non-consecutive days. While these methods can be effective for weight loss and improving overall health, they can also be beneficial for runners.
5K Runners
For 5K runners, intermittent fasting can be a useful tool for improving endurance and energy levels. One method that may work well for 5K runners is the 16/8 method. Here's an example of how a day of training and eating might look:
Morning:
Wake up and drink water
Go for a 30-minute run at an easy pace
Drink black coffee or tea before breaking the fast
Afternoon:
Break the fast with a high-protein meal, such as eggs and avocado on whole-grain toast
Have a small snack, such as an apple with almond butter, a few hours later
Drink plenty of water throughout the day
Evening:
Have a balanced dinner with lean protein, whole grains, and vegetables
Avoid late-night snacking and go to bed at a reasonable time
Benefits:
Improved endurance: Intermittent fasting can improve the body's ability to use fat as fuel, which can enhance endurance during a race.
Reduced inflammation: Fasting has been shown to reduce inflammation in the body, which can lead to improved recovery and reduced risk of injury.
Improved energy levels: Intermittent fasting can help regulate blood sugar levels and improve energy levels, which can be beneficial during training and on race day.
Risks:
Potential for muscle loss: If calorie intake is too low during the fasting period, there is a risk of losing muscle mass.
Decreased performance: Fasting can lead to decreased performance if the body does not have enough energy to fuel the workout.
Marathon Runners
For marathon runners, intermittent fasting can be a bit more challenging due to the higher energy demands of long-distance running. However, with proper planning and a strategic approach, it can still be effective. One method that may work well for marathon runners is the 5:2 method. Here's an example of how a day of training and eating might look:
Morning:
Wake up and drink water
Go for a 5-10 mile run at an easy pace
Drink black coffee or tea before breaking the fast
Afternoon:
Break the fast with a high-protein meal, such as grilled chicken and quinoa salad
Have a small snack, such as a handful of nuts, a few hours later
Drink plenty of water throughout the day
Evening:
Have a balanced dinner with lean protein, whole grains, and vegetables
Have a small snack before bed, such as a banana with almond butter
Benefits:
Improved fat burning: Intermittent fasting can improve the body's ability to burn fat as fuel, which can be beneficial for marathon runners who need to conserve glycogen stores.
Improved recovery: Fasting has been shown to reduce inflammation and improve recovery, which can be crucial for marathon runners who are putting their bodies through intense training.
Reduced risk of injury: Fasting can reduce inflammation in the body, which can help reduce the risk of injury.
Risks:
Risk of low energy: Marathon training requires a lot of energy, so fasting may not provide enough fuel to sustain long runs or intense workouts. It is important to make sure that you are still consuming enough calories and nutrients to support your training.
Risk of dehydration: Fasting can lead to dehydration if you are not consuming enough fluids. It is important to drink plenty of water throughout the day.
Overall, intermittent fasting can be a useful tool for runners, but it is important to consider the type of running you are doing and the potential risks. It is also important to approach intermittent fasting in a healthy and sustainable way, with the guidance of a healthcare professional if necessary.
Some additional tips for incorporating intermittent fasting into your running routine include:
Start slowly: If you are new to intermittent fasting, start with shorter fasting periods and gradually increase the length of your fasts over time.
Plan your meals: Make sure that you are consuming enough calories and nutrients during your eating window to support your training. Focus on high-quality, nutrient-dense foods that will provide sustained energy.
Stay hydrated: Drink plenty of water throughout the day to stay hydrated and support your body's natural detoxification processes.
Listen to your body: Pay attention to how your body feels during your fasts and adjust your approach as needed. If you feel lightheaded or fatigued, it may be a sign that you need to adjust your fasting schedule or consume more calories during your eating window.
When practicing intermittent fasting, runners may benefit from supplementing their diet with certain nutrients to ensure that they are getting all of the necessary vitamins, minerals, and amino acids to support their training.
Here are some supplements that runners may want to consider:
Protein powder: Protein is essential for muscle growth and recovery, and runners may need to consume more protein when practicing intermittent fasting to prevent muscle loss. Protein powder can be a convenient and easy way to increase protein intake, especially for those who have difficulty consuming enough protein through whole foods alone. Whey protein is a popular choice for runners, but there are also plant-based options available, such as pea or soy protein.

BCAAs: Branched-chain amino acids (BCAAs) are essential amino acids that can help prevent muscle breakdown during fasting periods. They can also help improve muscle recovery and reduce muscle soreness after workouts. BCAAs can be consumed in supplement form or obtained through protein-rich foods, such as meat, eggs, and dairy products.
We recommend: Promix BCAA Powder
Electrolytes: Electrolytes are minerals, such as sodium, potassium, and magnesium, that are essential for maintaining proper hydration and electrolyte balance in the body. When practicing intermittent fasting, it is important to make sure that you are consuming enough electrolytes to support your workouts and prevent dehydration. Electrolyte supplements can be added to water or consumed in pill form.

Omega-3 fatty acids: Omega-3 fatty acids are essential fats that are important for heart health, brain function, and reducing inflammation in the body. Runners may benefit from supplementing with omega-3s to support recovery and reduce the risk of injury. Omega-3s can be obtained through fatty fish, such as salmon or sardines, or through supplements, such as fish oil or algae-based supplements.

It is important to note that supplements should not replace a balanced diet of whole foods. Runners should aim to consume a variety of nutrient-dense foods, such as fruits, vegetables, whole grains, lean protein, and healthy fats, to ensure that they are getting all of the necessary nutrients to support their training.
Additionally, it is important to consult with a healthcare professional or registered dietitian before adding any supplements to your diet, as they can interact with certain medications and may not be appropriate for everyone.
In conclusion, intermittent fasting can be a useful tool for runners looking to improve their endurance, energy levels, and recovery. However, it is important to approach fasting in a healthy and sustainable way, and to consider the type of running you are doing and the potential risks. With proper planning and a strategic approach, intermittent fasting can be a valuable addition to your training routine.
