as everyone has said...yes it is possible.
is it going to be fun? HELL NO. it really will test the strength of your patience, it will drive you mad and toy with your anger emotions.
i lost 20lbs in about 3 months....an additional 5lbs a month later. took a lot of dedication. eating correctly, working out.
drink lots of water. eat a few times a day (small portions)....this will jump start your metabolism. be weary of your caloric intake. avoid alcohol!
load up your phone with lots of tv shows and movies for your cardio workouts...you're going to be spending lots of time on those machines.
