Proper nutrition is imperative to maximize athletic performance. Without enough carbohydrates, proteins, and fats, athletes may feel sluggish and fatigued during a workout or ravenously hungry. Athletes may also need to focus on specific vitamins and minerals for fitness performance, such as iron, vitamin D, and zinc.
How does diet affect your fitness?
Carbohydrates, both starches and sugars, provide the energy your muscles need to perform work. The carbohydrates you eat before you exercise not only burn as fuel but also accumulate in your muscles and liver as glycogen, a storage form of starch your muscles call on during exercise to keep them going.
