Nutrition affects hormonal balance during workouts by providing essential nutrients that regulate hormonal responses such as insulin, cortisol, and testosterone. A well-balanced diet supports optimal levels of these hormones, helping to manage energy, recovery, and muscle synthesis. For instance, consuming adequate protein post-workout can enhance muscle recovery through anabolic hormone release, while carbohydrates can influence insulin response for energy replenishment. Proper nutrition is vital for maximizing hormonal benefits during and after exercise routines.
