Many people have heard about the Ketogenic Diet, but did you know it is a viable solution for athletes as well?

The Ketogenic Diet is based around the principle of eating a very low amount of carbohydrates, and a very high amount of protein and healthy dietary fat, which puts your body in a state of “ketosis.”

The Ketogenic Diet also often advocates for not always eating breakfast, which is also consistent with the diet strategy intermittent fasting. Further recommendations for those people on the keto meal plan include drinking lots of fluids and keeping your salt intake stable.

The Ketogenic Diet has been gaining popularity over the past couple of years, and it is an effective way for many people to lose weight. However, many athletes shy away from it because of the concern it will reduce their performance and ability to exercise properly. After all, the human body does require regular carbohydrate consumption as a primary source of fuel.

So, can we maintain our muscle gains and athletic performance ability while being on an extremely low-carb diet?

Although it seems challenging, it’s completely possible!

There are many ways to get the energy you need for working out without compromising your Ketogenic Diet, even if you are a professional athlete!

The Ketogenic Diet can help athletes build an aesthetic physique and maintain their athletic function.

Keep reading below to find out the best way to exercise while in ketosis and how to use the Ketogenic Diet as an athlete.

Is the Ketogenic Diet Safe for Athletes?

To examine whether or not the Ketogenic Diet is safe for athletes, let’s look at a study (Nolan, Rush, Kaye, 2019) that was done on a 37 year of cyclist with Type 1 Diabetes who used the Ketogenic Diet to prepare for a 20 day, 4011km bike ride.

Type 1 Diabetes is an autoimmune disease in which the body does not naturally produce the required amount of insulin, forcing the individual to remain dependent on external insulin sources, as well as strictly manage their glucose intake. For the four years preceding the bicycle ride, the man maintained a very-low-carbohydrate Ketogenic Diet, where he consumed less than 25-30 grams of carbohydrates per day.

The bicycle ride itself was completed without any rest days, and certain days included over 250 km of riding. Ten days into the ride, the man experienced one episode of hypoglycemia, in which he interrupted his ride to administer carbohydrates to himself. During the ride, the average deviation of his blood glucose level was only 2.1 mmol/l, and he only spent 4.9% of the time with a blood glucose level above 10 mmol/l.

Although more research needs to be conducted with more controlled experiments, such as how quickly this diet can make positive effects on controlling glycemic variability for active people, these results demonstrate that a very low carbohydrate Ketogenic Diet can be useful for active people, specifically, those who are looking to control their blood sugar levels.

Furthermore, the validity of high-protein, low carb diets has been examined in numerous other ways as well. According to a study published in Nutrition Reviews,

“In short-term studies, dietary protein modulates energy intake via the sensation of satiety and increases total energy expenditure by increasing the thermic effect of feeding. Whereas these effects did not contribute to weight and fat loss in those studies in which energy intake was fixed, one ad libitum study does suggest that a high-protein diet results in a greater decrease in energy intake, and therefore greater weight and fat loss.

Additionally, according to a to a 2008 study published in The American Journal of Clinical Nutrition,

“In the short term, high-protein, low-carbohydrate ketogenic diets reduce hunger and lower food intake significantly more than do high-protein, medium-carbohydrate nonketogenic diets.”

How to Get into Ketosis for Athletes

The Ketogenic Diet works by putting your body into a state of “ketosis,” where the body begins to use body fat as a fuel source. However, you should be aware the body may also use lean muscle mass for a fuel source as well. Furthermore, you should be aware that although you may appear to burn body fat very rapidly, if you do not maintain a healthy amount of energy and nutrient intake, this weight loss will be accompanied by severe fatigue and you will not be able to maintain the diet.

When you are in a state of “ketosis,” the body produces ketone bodies through the conversion of fatty acids from body fat and the compound acetyl CoA (acetyl coenzyme A). These ketones become your primary fuel source while you are on a Ketogenic Diet.

Achieving a state of ketosis takes a lot of planning and focus, especially as an athlete, because otherwise, it can lead to significant health problems.

Here are some tips that can help you get into ketosis properly:

Lower You Carb Consumption:

The most crucial factor in achieving ketosis is reducing your intake of carbohydrates significantly. Under normal circumstances, your body will choose glucose as its primary source of energy.

Your body normally stores glucose in the form of glycogen in your muscles and liver, but when you reduce your daily intake of carbohydrates, this stored glycogen level depletes. As a result, the body must find another fuel source.

Most Ketogenic Diets advise a maximum of 50 grams of carbohydrates per day. In the study I previously mentioned, the cyclist consumed only 25-30 grams of carbohydrates per day and was able to function at a high level. You should reduce your carbohydrate intake gradually, so you do not shock your body too much.

Increase Your Protein and Healthy Dietary Fat Intake:

If you are going to lower your carbohydrate significantly to get into ketosis, you still need to provide yourself with ample nutrition through the forms of healthy dietary fats and protein. According to a study published in The American Journal of Clinical Nutrition, additional benefits of high-protein intake include:

  • Increased Satiety—protein generally increases satiety to a greater extent than carbohydrate or fat and may facilitate a reduction in energy consumption under ad libitum dietary conditions
  • Increased Thermogenesis—higher-protein diets are associated with increased thermogenesis, which also influences satiety and augments energy expenditure
  • Maintenance or accretion of fat-free mass

One of the problems of very low carbohydrate Ketogenic Diets is that you will likely end up consuming a lot of animal protein sources, instead of vegan protein sources. If you are going to eat a high protein diet, avoid red meat as much as possible. Red meat contains high amounts of saturated fat, which is a significant risk factor for heart disease.

You should attempt to eat as many unsaturated fats as possible, so foods such as salmon become an outstanding choice.

How to Exercise When You’re In Ketosis

If you’re interested in the Ketogenic Diet as an athlete, it is likely that you also want to know how to exercise while in ketosis before beginning the diet.

Even for non-athletes, one of the most common keto diet mistakes is foregoing physical activity. You don’t need to quit exercising just because you are on a low-carb diet. However, you may need to modify your workout routine until your body adapts to the reduced carbohydrate intake.

Exercising, even when in ketosis, has many health benefits. Exercising while in ketosis will help you to burn more calories while also maintaining muscle mass.

If you are an athlete and interested in the Ketogenic Diet (for weight loss or other reasons), controlling the timing and type of carbohydrates you eat is the key to successfully training well in ketosis.

How Athletes Can Use the Ketogenic Diet – The Targeted Keto Diet

A targeted Ketogenic Diet is recommended for those who do moderate amounts of exercise daily.

The targeted Ketogenic Diet involves the dieter consuming 25 to 50 grams of carbohydrates right before their workout, fueling their muscles for the duration of their training session.

I recommend that you consume something high in carbohydrates approximately one-hour before working out for the best results.

Not only do you want to consume a large number of carbs at this time, but you need to be wise about the carbs you choose as well. The best option is to consume complex carbohydrates which will provide energy for the longest amount of time possible.

Exercising on a Ketogenic Diet – The Cyclical Keto Diet

For those who do very high-intensity workouts daily, the cyclical keto diet is best for you.

The Cyclical Ketogenic Diet involves having one or two full days of high-carbohydrate consumption (refeeding days) throughout your week. Through doing this, you’ll be able to refill those muscle and glycogen stores for better energy overall!

You will be out of ketosis temporarily, but this is the best option to ensure maximal performance.

Even though you can consume a lot of carbohydrates overall, focus on lower-glycemic-index foods for better health and results. When re-entering ketosis, use this easy method after the refeeding days:

  • Day 1: Don’t eat anything after 6 PM
  • Day 2: Exercise (High-Intensity) and take in a very limited amount of carbohydrates
  • Day 3: Exercise (moderate-intensity) and go back to a normal Ketogenic Diet

The Best Keto-Friendly Foods for Athletes

If you’re an athlete looking to use the ketogenic diet, there are many keto-friendly foods that are delicious and nutritious.

Here are some of the best keto-friendly items that all athletes on the keto diet should add to their shopping list today:

Seafood

Shellfish and fish are well endowed with nutrients such as vitamins, selenium, and potassium, along with protein and healthy dietary fats. On the other hand, shellfish and fish have either no carb content or little levels of carb content. As asserted by Eco Watch, all species of freshwater fish and marine water fish do not have any carb content.

Also, crustaceans such as clams, squids, oysters, and mussels have little levels of carbohydrates. Shrimps have no carb content.

Shellfish and fish have higher levels of omega-three fats.

Therefore, make sure that you incorporate seafood into your diet at least two to three times each week.

Low-Carb Vegetables

Vegetables such as spinach and kale, cauliflower,  and broccoli have lower levels of carbohydrates. Also, these vegetables have high levels of vitamins, antioxidants, fiber, and minerals.

Therefore, non-starchy vegetables should form part of your everyday Ketogenic Diet. These vegetables can act as excellent substitutes for foods rich in carbohydrates.

For instance; you can have cauliflower instead of rice or mashed potatoes, and spaghetti squash instead of traditional spaghetti.

Olives

Olives are rich in antioxidants. Oleuropein is the primary type of antioxidant in olives. This antioxidant helps to reduce blood pressure. It will also prevent you from losing bone mass.

Olives generally have a low carb content. However, their carb content varies since they come in different sizes. A one-ounce serving of olives will have a carb content of two grams and a fiber content of one gram. Therefore, olives are keto-friendly.

Cheese

Cheese contains little levels of carbohydrates and higher levels of fat. Due to this, cheese is keto-friendly.

Cheese also contains conjugated linoleic acid, a nutrient that will help you to strengthen your bones and muscles. However, be careful not to consume too much saturated fat from cheese.

Avocados

One half of a medium-sized avocado contains about two grams of net carb content. Due to their lower levels of carbohydrates, avocados are keto-friendly.

Avocados contain a variety of vitamins and minerals, while also containing high amounts of healthy dietary fats and protein.

Seeds and Nuts

Seeds and nuts such as almonds, cashews, brazil nuts, pumpkin seeds, sesame seeds, macadamia nuts, pecans, pistachios, chia seeds, and walnuts are keto-friendly because they have a high-fat content, moderate amounts of protein, and a low carb content.

When you frequently incorporate seeds and nuts into your diet, you lower the chances of suffering from heart disease, depression, and cancer. Seeds and nuts also have a high fiber content.

You can read more about low-carb nuts and seeds here.

Poultry and Meat

If you are on a ketogenic diet, then poultry and meat are important because they have no carbohydrate content. However, they contain many vital vitamins and minerals, along with high levels of proteins. The most prevalent types of minerals found in poultry and meat include potassium, zinc, and selenium.

The healthiest type of red meat is grass-fed meat. This type of meat is higher in omega-three fats, antioxidants, and conjugated linoleic acid. These nutrients will help in the reduction of your blood pressure levels.

Choose white meat, instead of red meat, when possible.

MCT Oil

What is MCT oil, you ask? MCT stands for Medium Chain Triglycerides, which are comprised of medium-chain fatty acids.

MCT oil is particularly advantageous because it is easy for the body to digest and absorb as energy. Unlike other fats, MCTs do not need bile or other pancreatic enzymes to help break them down.

Instead, they are smaller in size so they are readily absorbed by the small intestine and transported to the liver, where they are converted into ketones.

This means that MCTs are easily used by the body for fuel rather than being stored as fat.

MCT oil has anti-microbial and anti-inflammatory properties so it is helpful in maintaining optimal gut health by eliminating harmful gut bacteria.

One tablespoon of coconut oil consists of about 60% medium-chain triglycerides (MCTs) whereas the remaining 40% is made up of other fats.

MCT Oil is the perfect supplement for adding with your smoothies, coffee, tea, and protein shakes.

You can visit KetoaHolics for getting your hands on the best version of MCT Oil available.

The benefits of MCT Oil and Coconut Oil are both impressive, and you can freely use whichever you desire if you are on the ketogenic diet.
