Pre-run: black coffee, calorie-dense snacks, and breakfast
Training for a marathon on a keto diet is challenging, especially if you are new to this type of diet. It can take weeks or even months for your body to adjust to ketosis, and you are likely to feel tired and hungry during this transition period.
If you plan to run in the morning, it is generally recommended to eat breakfast beforehand. However, some runners experience cramps from running on a full stomach. If this is the case for you, consider having a moderate amount of black coffee for an energy boost and bringing some calorie-dense snacks, such as peanut butter balls or cheese sticks, to eat during your run. You can then eat a larger breakfast after your run.
It is important to remember that keto diets are typically low in carbohydrates, which can be a challenge for marathon runners who need a lot of energy. To ensure you have enough fuel, focus on consuming healthy fats and lean proteins. Fatty fish like salmon, mackerel, and sardines are great options, as they provide omega-3 fatty acids. Chicken, turkey, and lean cuts of beef are also good choices for muscle support. Avocados and nuts are excellent sources of healthy fats, which will help maintain your energy levels during your run.
In addition to your diet, staying properly hydrated is crucial when training for a marathon on a keto diet. Water and electrolyte-infused drinks, such as coconut water, will help replenish lost electrolytes and keep your body functioning optimally.

During the marathon: keto-friendly sports drinks, water, and electrolytes
While training for a marathon on a keto diet, it is important to stay hydrated and maintain your electrolyte levels. Water is essential, but it is also a good idea to consume electrolyte-infused drinks, such as coconut water, to replenish lost electrolytes. Bone broth is another option, as it provides necessary sodium and minerals.
You can also consider keto-friendly sports drinks, which can provide endurance support and help you maintain your energy levels during the marathon. These drinks can be a good source of carbohydrates, which are important for marathon runners, even those on a keto diet. However, be mindful that some sports drinks may contain a significant amount of carbohydrates, which can affect ketosis.
Some runners choose to bring their own fuel in the form of calorie-dense snacks or gels, which can be consumed during the marathon to provide a quick energy boost. Examples of keto-friendly snacks include frozen peanut butter balls, dark chocolate, cheese sticks, and bacon strips.
It is worth noting that some keto runners choose to slightly increase their carbohydrate intake leading up to a marathon. This can be done by consuming keto-friendly sources of carbohydrates, such as sweet potatoes, bananas, or rice. This strategy may help top off liver glycogen stores and prevent a sudden drop in blood sugar during the race.
Overall, staying hydrated and maintaining electrolyte balance is crucial during a marathon, especially when following a keto diet. By planning and experimenting with different keto-friendly options, you can find the best approach to fuel your endurance and energy needs during the marathon.

Post-race: a hearty meal with fatty meat, collagen-rich bone broth, and supplements
After completing a marathon, it is important to replenish your body with a hearty meal that includes fatty meat, collagen-rich bone broth, and supplements. Here are some suggestions for each component:
Fatty Meat
Fatty cuts of meat are an excellent source of high-quality fats and proteins, which are essential for muscle repair, recovery, and growth. Look for grass-fed beef, butter, or fatty fish like salmon, mackerel, and sardines, which also provide omega-3 fatty acids.
Collagen-Rich Bone Broth
Bone broth is a nourishing food that provides your body with amino acids, collagen, and protein. It is particularly beneficial for joint and skin health. Opt for bone broth made from 100% grass-fed and grass-finished cattle bones, simmered with organic vegetables and herbs. Drinking bone broth regularly, either on its own or incorporated into recipes, can provide your body with collagen-rich goodness and support your overall health.
Supplements
Ketogenic diets and ketone supplements have gained popularity among endurance runners as they may delay the onset of fatigue and enable the body to utilize its fat reserves more efficiently. Consider taking ketone esters, ketone salts, medium-chain triglycerides (MCT oil), or exogenous ketone supplements to support your body's energy needs and recovery process. Additionally, natural electrolytes can help prevent fatigue and cramps, so consider adding a little salt to your water or supplementing with electrolyte-rich drinks like coconut water.
Remember, it is important to listen to your body and adjust your diet and supplementation according to your individual needs. The above suggestions provide a general framework for a post-marathon keto meal plan, but feel free to consult with a nutritionist or dietician to tailor it further to your specific requirements.

Common mistakes: forgetting electrolytes, inadequate protein intake, and low-calorie intake
Training for a marathon on a keto diet is challenging, and it's crucial to avoid common pitfalls to ensure optimal performance and health. One such pitfall is forgetting about electrolytes. Electrolytes, such as sodium and potassium, are essential for maintaining proper fluid balance and nerve function during endurance exercise. When following a keto diet, the body tends to excrete more electrolytes, so it's important to replenish them. Coconut water and bone broth are excellent sources of electrolytes and can help prevent muscle cramps and fatigue.
Another mistake to avoid is inadequate protein intake. Protein is vital for muscle repair and growth, and a lack of protein can lead to muscle loss and decreased performance. Lean proteins such as chicken, turkey, fish, and beef can support muscle recovery and growth. Additionally, high-quality protein sources like fatty fish provide omega-3 fatty acids, which have anti-inflammatory properties that can aid in reducing exercise-induced inflammation.
A keto diet is typically low in carbohydrates, but when training for a marathon, it's essential to include some keto-friendly sources of energy, such as MCT oil or fatty cuts of meat. However, one common mistake is a low-calorie intake, which can leave you feeling exhausted and impact your training. To avoid this, ensure you're consuming enough calories to support your energy needs. Calorie-dense snacks like peanut butter balls can provide a quick energy boost before or during your runs.
Additionally, it's important to be mindful of your body's transition to ketosis. Initially, you may experience fatigue and hunger as your body adjusts to using fat as its primary fuel source. This transition period can take weeks or even months, so it's advisable to adopt the keto diet during off-season or lower-intensity training periods to minimize the impact of low-energy days.
In summary, when training for a marathon on a keto diet, it's crucial to prioritize adequate electrolyte and protein intake, ensure sufficient calorie consumption, and be mindful of the transition period to ketosis to optimize your performance and overall well-being.
