> Sometimes after a really hard boxing practice I can be so hungry that I physically can't eat any more food, but I'm still hungry.

For me it is the complete opposite - I can't eat or even think of food for a while, and am definitely not hungry or have any appetite -- and the harder the practice is, the longer it takes appetite to recover. (My practice of choice is thai boxing, btw...)

This is usually an hour after practice. Takes a while to get home, take a shower, prepare the food etc.
