Reduce fatty foods from your diet significantly. In some cases there are no "non fat" options for the food you really like. Eat less of these or if you are seriously overweight, eliminate them from your diet completely for a while. If your original diet includes significant amount of fatty or greasy food, substitute them from the other food groups.
Kiss your love partner passionately more often (more than 10 times a day). Kissing is a surprisingly effective way to burn calories. Physical activity between partners is also a great way to burn calories. According to several studies, kissing for more than 10 minutes a day can trim up eight pounds off your body per year.
