What Happens to Nutrients In The Body When Exercising?

When exercising, the body uses energy from stored nutrients to fuel muscle contractions and support physical activity.

The primary source of energy for exercise comes from carbohydrates stored in the muscles and liver as glycogen, which is broken down into glucose and used for energy.

When glycogen stores are depleted, the body turns to fat stores for energy. Exercise can also increase the body's need for certain nutrients, such as protein, to support muscle repair and recovery.

Proper hydration is also important, as sweat loss during exercise can lead to dehydration and affect performance. By fueling the body with a healthy diet that provides enough carbohydrates, protein, healthy fats, and fluids, you can ensure that your body has the resources it needs to perform at its best during exercise.
