To "eat for fuel" means selecting nutrient-dense foods that provide energy for physical activity and overall health. This approach emphasizes foods that help optimize performance and recovery, such as complex carbohydrates, lean proteins, and healthy fats. Eating for fuel prioritizes quality over quantity, focusing on whole, minimally processed foods rather than those high in sugar or unhealthy fats. The goal is to sustain energy levels during workouts and daily activities while supporting muscle recovery and maintaining a healthy body composition.
