Eat less, move more
It's the only thing that works. Repeat until desired effect is achieved.

It's not just filling your face with generic BooBooBurgers that does it. If you take in 50 calories a day more than you need, (i.e. a single digestive biscuit), then over time you will gain weight. Over a year, assuming a 1500 calorie-per-day diet, that equates to an extra 12 days worth of calories. Fat and sugar are all too easy to get and very hard to avoid in the current western diet.
