We are trapped into being overweight by our technologically advanced society, to be fair about it. But we can never use that excuse to stay unfit, for the price is an early grave.

The prescription for being overweight is to exercise long and hard (after getting your body in shape to handle it). This is what stimulates the metabolism to continue to burn extra calories for hours afterwards. Twice a day, in the morning and at night, continues this effect. Alternating heavy days with lighter days allows your muscles to recover and avoid overtraining. Once you overtrain, it may take weeks to fully recover. Don't be in a hurry: it took years to put the weight on, didn't it? Listen, don't waste time with expensive gimmicks, diets or pills! Exercise, it's free! And once you reach your target, you'll find it's easier to maintain that weight than it was to lose it, as long as you keep exercising regularly.

That's why, for me, commuting by bike/walking is perfect. Twice a day, I ride or walk. When I get home, I already have done my workout. And I don't feel guilty eating a lots of nutritious food, because I know my body needs to eat to stay strong.

Another tip for losing weight is to eat more "low density" foods, like vegetables. They fill you up without the extra calories.
