you need a lifestyle change. eat lots of fruit,vegetables, and lean protein. STAY AWAY FROM JUNK FOOD. try to be more active by walking, running,biking, or swimming. you should also drink at least 8 cups of water a day.
My wife and I have been using a system that a friend of mine turned me onto, bought it online and it was really cheap compared to a lot of the stuff on the market, you can find it here http://tinyurl.com/4a2h8jFollowing this program is working great for both of us. I have lost about 10 pounds in the last month and my wife is around 7. We had tried tons of programs and nothing worked but my friend swore by this and he told me he lost a total of 40 pounds and reached his target weight and feels great. My wife and I are well on our way and I am hoping to lose another 10 by August so I m not fat at my high school reunion...lol Hope this helps a little.
