There is an obvious need for sufficient calories during intensive training. Not so obvious are how much and how often we should consume specific nutrients. Protein, carbohydrate and water are not easily stored in the body, forcing us to consume them regularly. Hunger and thirst sensations serve as reminders of our needs, but these sensations don’t tell us the best combination and timing of nutrients for driving health and performance. For example, we often don’t feel hungry right after waking in the morning or after exercise even though the body has low blood and amino acid levels at those times.
