Lower the thermostat overnight. There was a small study recently that suggested sleeping cooler had metabolic gains. It doesn't have to be frigid, just cooler.
Beyond that, keeping your body fueled properly helps a great deal.
You might also want to look into diversifying your exercise plan - just walking may not be enough for the results you're seeking.
