What is a potential negative effect of high dietary fiber intake before exercise?

High dietary fiber intake before exercise can lead to gastrointestinal distress, which can hinder performance and cause discomfort during physical activity. Fiber is known for its ability to promote digestive health and regularity; however, consuming large amounts shortly before exercise may lead to symptoms such as bloating, gas, cramping, or diarrhea. This discomfort can distract from the workout and may limit one's ability to perform effectively, making it a significant concern for athletes and individuals participating in exercise.

On the other hand, while improved endurance, hydration, and reduced muscle fatigue are beneficial outcomes of proper nutrition and adequate hydration strategies, they are not direct consequences of high fiber intake before engaging in exercise. Therefore, it is important to be mindful of the timing and amount of fiber consumed in relation to physical activity to avoid any negative impacts on performance.
