Lower the temperature of your room and your body will have to burn more calories to compensate. It's not really going to make a significant change to your weight though (and obviously don't be dumb and take this to an extreme and freeze yourself). Increase your base metabolic rate (i.e. calories your body burns at rest) and you'll lose more weight without doing anything. Weight lifting is the most bang for buck way to significantly improve your metabolic rate without also eating back all the calories in the process (a problem with long aerobic exercise). Look into a simple bodyweight exercise routine like DDP yoga and just start doing a little bit every day--even as little as 10 mins or so a day/an hour a week will bring significant benefits over a few months.
