To eat or not to eat before a training session.

In the first case, our body is likely to lack energy which would reduce performance, and increase risk of injury.

In the second case, training on a full stomach could cause discomfort/sluggishness and/or your system would concentrate on digesting instead of providing the energy your muscles need during physical activity.

Ideally, you should eat carbohydrates (or carbs.) from sources such as cereals, fruits or vegetables before training, and avoid fat foods which require more time to digest, as well as food you know could cause discomfort.
