I have had great success using both LA Weight Loss and Weight Watchers. That was some of the best money that I ever spent. Accountability and journaling are what make all the difference for me. You might surprise yourself about how much a nibble here and there add up calorie wise. Also, I have had difficulty losing weight when I don't eat enough food. Journaling keeps me right smack dab where I need to be.

I generally follow a 1200-1400 calorie diet using The Calorie King book (that is now that I don't go to either Weight Watchers or LA Weight Loss) and on days that I ride hard I add calories according to how many I have burned using this calculator:

Both LA Weight Loss and Weight Watchers are pretty much low carb diets.

I lose weight faster when I am not exercising/training. I know the reason is that when I train hard I tend to be more tired and therefore don't want to mess with journaling and I also have less determination to leave the snacks alone.

Hope that helps.
