During medium- to high-intensity training, what type of diet is generally not advised?

During medium- to high-intensity training, a low-carbohydrate diet is generally not advised because carbohydrates are the primary source of energy for such physical activities. When engaging in intense workouts, the body relies heavily on glycogen stores, which are derived from carbohydrates. A low-carbohydrate diet can lead to limited glycogen availability, resulting in decreased performance and increased fatigue during workouts.

Carbohydrates provide the necessary fuel to sustain intensity and support endurance, making them crucial for athletes and individuals participating in rigorous training. Insufficient carbohydrate intake may hinder an athlete's ability to train effectively and recover adequately after workouts. Therefore, maintaining an appropriate level of carbohydrates in the diet is essential for optimizing performance and promoting overall training benefits.
