The main focus of a high-carb diet plan is to provide the body with an adequate supply of carbohydrates, which serve as the primary energy source for high-intensity activities. This diet is often favored by athletes and active individuals to optimize performance, recovery, and overall energy levels. Emphasizing complex carbohydrates such as whole grains, fruits, and vegetables ensures a steady release of energy while supporting muscle glycogen stores. A well-balanced high-carb diet can enhance endurance and help sustain optimal athletic performance, particularly during prolonged exertion.
