A few folks have asked what kind of pedometer I have - the folks at the show gave me an Omron brand. My husband got one (an even newer, fancier version!) on Amazon for $30 (I think). It's really nice because it has a memory feature so when I'm reporting my steps to Dr. Roizen and have missed a day, I can easily look back and see how many steps I had.
The other thing I use a lot is an application on my iPhone called Loseit.com. I have always thought that keeping a food log would be incredibly burdensome. Once I've gotten going with this one, it's super easy to use and keep up with. Especially when you generally eat the same things over and over again - it has a nice feature where you can call up a previous meal and just copy it to another day. All on-line food journals have some shortcomings in terms of not having all the foods that you might eat, but this is pretty good. It also has an export report option which is great for sending summaries to Dr. R.! (Oh, and it's free!) And when you put something in on the phone it automatically updates it on the computer, and you can track progress over time.
