My advice is: don't hammer it too hard everyday... Ride at a lower intensity. Follow a well balanced diet with plenty of protein. The more you weigh and the more physically active you are the more protein you will require for recovery...I think one of the reasons why I've been able to commute and ride daily and still keep up with my physical labour job and strength workouts is because majority of my rides are done at a low-medium intensity. Sure I could hammer hard if I wanted to but I know it would only lead to a burn out and compromise my recovery.
