If Dave comes on whatever he says may trump this but if you feel good endurance wise, strengthwise etc and you think you could perform with that then I would go ahead and add in more carbs in a controlled way also. Protein is not steroids
. But it could be that just adding back in the carbs, if you do it carefully, will get your muscles holding more gycogen and thus more water (in the muscles not "bloating") and so get your weight back up pretty quickly. Obviously you don't want to put on fat so you'll have to put the carbs in the right place. Do you not do any weight work?
