Keto diet (ketogenic diet) is a low-carb, high-fat diet. It involves consuming a small amount of carbohydrates and replacing it with fat to help burn the fats in your body to energy. It can also burn fat into ketones in the liver which can supply energy for the brain. This process of breaking down fat for energy is called Ketosis.
Pros and Cons of Keto Diet for Athletes
The current version of the keto diet allows you about 20% protein but restricts carbohydrates to 10%.
“The keto diet is all about cutting carbs and eating more fat. Here’s what the daily breakdown of carbs, protein, and fat looks like:
5 percent of calories from carbohydrates, including low-carb, non-starchy vegetables and small amounts of leafy greens. The keto diet excludes carb-rich foods like grains, beans, fruits, and starchy vegetables.
20 percent of calories from protein, such as meat, eggs, and cheese.
75 percent of calories from fat, such as oils, unprocessed nuts, butter and avocado”.
Eating between 20g and 50g of carbohydrates each day would take you two to four days to enter ketosis. However, the time it takes for this to occur varies based on several factors such as (age, carbohydrate, fat, and protein intake, physical activity level, sleep health metabolism, and stress level.
If you eat a high-carb diet before starting a keto diet, it may take you longer to reach ketosis than someone who consumes a low-carb diet. Do you know why? Because your body needs to exhaust its glucose first.

These can lead to a lower risk of cardiovascular disease and other health problems.
Improves athletic performance: The keto diet can increase the body’s ability to break down fat for fuel which can lead to increased endurance in athletes.

Keto diet also leads to inflammation.
Disadvantages(Cons) of the keto diet in athletes.

Highly restrictive and difficult to follow: Keto diet can be difficult to follow as it requires dedication, adherence, consistency, and endurance. Being a strict (restrictive) diet, it can cause rebound weight gain because people tend to crave for the foods they are avoiding.
Reduction in athletic performance: The body takes time to adapt or adjust to using fat for fuel (energy) and while it is in this stage, performance may decline. It is a short-term reduction in athletic performance and can be called “Keto flu“.
Side effects: An athlete could experience the downside (side effects) of the keto diet during its initial stages as the body tries to get accustomed to ketosis. Some of these side effects include:
Fatigue: As the body is adjusting to the use of fat as its primary source of energy, it could cause fatigue (tiredness, lack of energy, and difficulty in concentration) in athletes.
Muscle cramps: This is caused by electrolyte imbalances because the keto diet can cause the body to excrete electrolytes such as sodium, potassium, and magnesium.
Gastrointestinal upset: Gastrointestinal upset such as nausea, constipation, and diarrhea is often caused due to changes in the diet and the body’s adaptation to ketosis.
Keto breath: Keto breath is a bad breath caused by the production of ketones. It is temporary and goes away as the body adjusts to the diet.
