Eating during a night poker session can be beneficial for sustaining energy levels and maintaining focus. However, it's essential to choose foods that provide sustained energy and avoid heavy or greasy options that could lead to sluggishness or discomfort. Opt for nutritious snacks like fruits, nuts, protein bars, or small sandwiches that provide a balance of carbohydrates, protein, and healthy fats. Additionally, stay hydrated by drinking water or non-caffeinated beverages to avoid dehydration, which can impair cognitive function. Overall, eating mindfully and choosing the right foods can support optimal performance during a night poker session.
