Before Training
As a Goalkeeper, you need to have lots of energy to maintain a high performance. Before training, you should consume a meal containing lots of complex carbohydrates.
For example, a good meal before training could be two Weetabix biscuits with semi-skimmed milk and a (200ml) glass of orange juice.
Energy comes from carbohydrates. Weetabix is suitable for a goalkeeper's diet as they contain high amounts of carbohydrates, which use energy slowly. Weetabix is also low in fat and sugar. This benefits the goalkeeper as it avoids weight gain.
