I wanted to post again that you really should focus on body fat and not the scale. There's plenty of people in the C&A forum here that advocate what I consider starvation diets (1500 cal/day with 17 miles of riding, Sinister1???), and that's a fast way to lose weight AND a great recipe for muscle loss, poor nutrition, and altering your metabolism.
If you think of it as "dieting" you are almost 100% guaranteed to gain it all back when you revert to your old eating habits. A starvation diet will only exacerbate this. It takes years to gain the weight, and it will take awhile to lose it.
