Hi Jennifer,
It sounds like you're really on the right track!!
How long did it take you to put on those 15lbs of lard? Don't expect them to go away in a "poof" when you worked so hard putting them on (and yes...I worked hard to put mine on too).
Fitday is a good idea, sometimes there are hidden carbs.
The "bars"...I've got a question on them. Look at the "nutrition label" not the "net carbs" and post what you see in the carbohydrate section. I'm curious because a lot of those bars with low "net carbs" contain tons of sugar alcohol that stall many people (including me).
One other thing...are you exercising?
For me it works like this: Your body uses up carbs 1st because they're easiest to process, then fat, then muscle.
If you exercise, you get through the carbs quickly and since your body needs energy, it has no place to go but to the fat.
If you want to see a profound difference, just look at the before, in progess, and "success" photos of a lot of the people here.

The link is to one persons journal who has made an amazing change. You'll see the fat really does drop off.
GL low carbing...stick with it...it WILL happen if you're true to it.
