I dunno, my weight loss, which I've been maintaining well, was pretty hunger-free. Veggies and fruit are great snacks for making you feel full yet not upping the calories too bad. Also, drinking lots of water seemed to help. I always woke up hungry (which I think is good), but I wasn't very often hungry during the day.
I do agree that while you can do lots of low intensity base-mile type cycling, you have to be careful about trying to train seriously and cut back on calories at the same time. it's sort of a one or the other kind of situation.
But yes, no reason to pay anyone for something you can do on your own with will power and the help of some free calorie tracking programs.
