you need to be really careful about being under the limit on protein in particular, you want to build muscle not burn it up and for that you need protein!

try cycling or swimming - neither is as damaging to the body as running, cycling is in my opinion the way to go esp if it means that you can ditch the car for a couple of journeys a day - of course as it is more efficient than running you have to put in a lot of effort to burn the same calories per hour.
