The High-Fat, Low-Carb (HFLC) or Keto approach to long distance endurance racing is a dietary strategy that emphasizes the consumption of high amounts of fat and low amounts of carbohydrates.

By training the body to burn fat as its primary fuel source, athletes can improve their endurance and reduce their reliance on glycogen stores, which can become depleted during long-distance races. Some athletes and coaches have reported positive results with this approach, including improved endurance and faster recovery times.

However, it should be noted that this approach is still relatively new and more research is needed to fully understand its potential benefits and risks. Additionally, it is important to note that individual needs and goals can vary, and any changes to one's diet should be done under the guidance of a healthcare professional.

(!) Use this plan with caution and never jump right into it if you are new to the HFLC approach. This plan should only be used as a supplementary plan and is not intended to replace a balanced diet. It is also not suitable for persons under the age of 18.
