Exercise is a supplement to weight loss - it will not cause you to lose weight without changing your diet. There are only three real rules for dieting:
1. Eat less junk (you know what it is).
2. Eat more of the right stuff (you also know what that is).
3. Eat smaller portions.
Then, add 4-5 hours of biking each week and the weight will fall off, guaranteed.

That's it. No books, no plans, no diets, no cost.

You don't lose weight with exercise alone because exercise makes you hungry. I ate a 1200 calorie lunch today, but I rode 50 miles and burned probably 2200 calories. Also, it's not true that the only consideration is calories in vs. calories out. Two hundred calories from an apple is different than 200 calories from a donut.
