One, cut out the junk food and the fast food. I've known people who lost like 20 pounds just from doing that alone. Also, not drinking so much beer or sodas has done the same thing. If it seems hard then buy some fruit or other replacement snacks and find a hobby to take your mind off wanting to eat (I understand a lot of people who overeat do so because they're bored).
Also, be warned that I've read that dieting can cause the body to regulate its metabolism so that it burns food much more slowly (as the body thinks food is scarce and must make it last longer) which results in making it harder to lose weight (and easier to gain it). That is, cutting out the junk and fast food probably should be replaced by eating something like grapes or raisins so that the body doesn't react to the fear of starvation.
You can burn calories by "running in place" while watching movies. But if you weigh a lot this puts a lot of pressure on your legs and can cause some discomfort until you get used to it (in I'd guess a few days).
Much better, IMO, is to join a fitness center...but GO. I've noticed that many new members show up after the holidays but only show up for a month or so before never showing up again. Don't do that. This is something that takes time, and what's much better is that you can actually get high from it if you do it long enough, and that also helps flush toxins from your body so that you're less depressed as well as more healthy in general. Much more importantly, you can become addicted to the high of it so after awhile you look forward to going rather than having to force yourself to.
Many fitness centers (even some YMCAs) have TVs you can watch while exercising, and many also find it helpful to take headphones to listen to. Some also do some light reading but I've personally found it too jarring to read most of the time. The best, IMO, is having someone to talk to while you both exercise.
While there I strongly recommend the sauna, if they have one. Try starting for about 10 minutes and then take a brief cold shower and doing it again. It can be quite the shock and very jarring but I (along with others) have found this incredibly blissful as well. You'll sweat a lot of water weight out that way, too. You can also use aromatherapy by squirting scented water onto the burner (though I personally avoid this, at least unless I can get permission, if others are also using it). But when starting out you should not stay in for more than 10 minutes at a time (unless the temp is low). As you get used to it then you can stay in even longer and it just gets even better.
It might also help if you have a friend who is also looking to lose weight (or is already a fitness freak) so that you have encouragement until you no longer need encouragement (and can help each other pass the time while exercising by talking as you use side by side stair masters, treadmills, etc). Do remember that losing weight and getting a better body takes time, so don't plan for actual, stable results for several weeks at least.
Anyway, good luck.
