No, seriously, if you weren't hungry after that there would be something wrong with you. Go eat! You need it. I need to eat a lot after weightlifting too, for the rest of the week. Everyone does after exertion, its normal. I think you will do yourself harm if you don't have you fill in these circumstances.
