Yesterday my kid's grandma fed him dinner and, as she always does, she stuffed him full (was rice, meat, noodles, soup). Then right after that I took him to play pickup soccer for about 1.5hrs. To my surprise he was very energetic and assertive in his playing. Have you experienced this with your kid? I had always tried to have him not eat much right before a game, maybe eat something light about an hour before. But now I'm rethinking it. Also, maybe for kids it's different than for adults. Maybe for kids their metabolism is so optimal that the food they eat gets turned into energy quickly and the cells burn that fuel with high efficiency? Also, maybe it depends on the kind of food? Have you noticed anything in particular with regards to timing of eating?
