Question: how many calories to eat before workout?
Answer: The closer your pre-workout meal is to your workout, the smaller it must be. If you have only a couple of hours before your workout, then eat a small meal of 300 – 400 calories. No time for a meal? Then have a small snack (e.g. bananas, yogurt or porridge) or a smoothie 30 – 60 minutes beforehand.
