This could be a misconception of mine but I always thought swimmers should be ravenous after swim practice. My son (13) swims for 2-2.5 hours and does not want to eat dinner after practice. He eats about 30 minutes before he leaves for practice but it's not a huge meal. Most days he skips dinner and goes to sleep without eating anything. I am concerned because 1. shouldn't he re-fuel his body after practice? and 2. not sure he is getting enough nutrition to sustain the level of effort that is needed. At the same time I want to trust his body to let him know when and how much he needs to eat. When I ask him he will say he is not hungry. Any advice?
